Macroeconomic Stability Implications of GTP-II: Evidence from Macro -Econometic Model for Ethiopian Economy
Creators: name: Bizualem, Anteneh
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2016

description: This study tries to use a macro econometric model for policy analysis purpose of the Second Growth and Transformation Plan. First the macro-econometric model is developed for Ethiopian economy based on aggregate supply and aggregate demand framework. The model is composed of total 65 equations, out of which 12 equations are estimated equations and the rest are either identity or bridging equations. After the model is developed, how it performs with historical data is checked by performing dynamic simulations for the sample period 2000-2014 and it has performed well in tracing historical values. After the model performs well with historical data it is used to simulate for the two scenarios of the Second Growth and Transformation Plan: the increase in the government investment by 10 percent and an external shock which is an increase in import price by 10 percent. When the government investment increases by 10 percent, it has an increasing impact on the output of the economy. On the other hand, it creates an inflationary pressure. This shows that it may have a macroeconomic instability problem. When the import price increases by 10 percent, it has a negative impact on the output of the economy and also leads to an inflationary pressure. But the inflationary pressure that comes from the increase in the public investment is higher and leads to more macroeconomic instability problem. To avoid or minimize the instability problems that arise from these policy shocks the government should be cautious and take preventive actions accordingly. In general, the Second Growth and Transformation Plan has to be undertaken in a matter of which its effect on the economy's stability is minimal and the government should follow different measures to avoid the worst scenario
The Role of International Remittance on Economic Growth in Ethiopia: An Autoregressive Distributed Lag Approach
Creators: name: Tilahun, Mikias
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Having the general objective of investigating the role of international remittance on economic growth in Ethiopia, this study have used an auto regressive distributed lag (ARDL) model or Bound Testing approach to cointegration. The data used is from World Bank Development Indicators which spans from 1981 to 2012. The outcome of the study revealed that, the long run growth impact of international remittance during the study period is positive and significant. However, the short run effect is found to be negative and statistically significant, showing the consumption smoothing role of remittance income in the short run. Apart from this, other growth determinant factors, such as human capital, labor force and gross fixed capital formation are found to significantly and positively affecting growth in Ethiopia. Moreover, the Granger Causality test has confirmed that there is a unidirectional causality which runs from remittance to output. The most important policy implication that comes out of this study is that the government as well as other concerned stakeholders should work on easing the remittance sending process and cost, so as to better extract the economic benefit of international remittance.

The Impact of Relationship Marketing on Customer Loyalty in Banking Industry, The Case of Bank of Abyssinia
Creators: name: Bekele, Shifera
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: The survival of any organization depends on its customers. Customers are the source of profits to be earned by a profit making organization. Due to the more and more fierce competition in toads business, many companies are required to build long-term profitable relationship with customers and to achieve customer loyalty. Therefore, relationship marketing has become more and more important since last decade of 20th century, especially in service industry. There are many different relationship marketing dimensions implemented for retaining customers��. Therefore, this study is aimed to explore the impact of relationship marketing dimensions (trust, commitment, conflict handling, and empathy) on customer loyalty, by focusing on the Bank of Abyssinia. A theoretical framework was used as a guideline to test the relationships between relationship marketing dimensions and customer loyalty. A quantitative method which is cross-sectional study with deductive approach is chosen in this research. In order to collect primary data, a self-completed questionnaire is designed and was randomly given to the customers of the Bank of Abyssinia. In addition to questionnaire, semistructured interview questions are prepared to get information from the organization which is analysed qualitatively. The SPSS version 16.00 for windows is used to process the primary data which is collected through questionnaire. The findings show that relationship marketing dimensions have impact on customer loyalty. All the independent variables are positively and directly related to customer loyalty particularly in Bank of Abyssinia and in general in banking industry. The relationship between relationship marketing and customer loyalty is significant. Therefore, banks should make the whole system on work with customers, not in opposite of customers. And also they are expected to invest more on attracting new customers and retaining the existed ones with regard to relationship marketing to increase customer loyalty. Key words: Relationship Marketing, Trust, Commitment, Conflict Handling, Empathy, and Customer Loyalty.
Determinants of Ethiopian export on five selected commodities: a time series analysis
Creators: name: Zelealem, Melese
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2019

description: The study investigates the export performance of the five selected commodities of Ethiopia namely: coffee, oil seeds, chat, meat and meat products and fruits and vegetables and their determinants during the period 2003/2004 - 2017/18 using a secondary data extracted from National Bank of Ethiopia (NBE), Ethiopian Revenues and Customs Authority (ERCA) and Central Statistics Agency (CSA). To analyze the relationship between the export commodities and their determinants, gross domestic products (GDP), real effective exchange rate (REER) and trade openness (TOP) were used, an Autoregressive Distributive Lag (ARDL) model have been used. The model helps to investigate the long run and short run relationship between selected commodities and their determinants. The result from econometric analysis revealed that the GDP is the only variable significantly and positively affects the export of the selected commodities. While TOP positively and significantly affects the export of coffee and chat, REER significantly affects the export of fruit and vegetables however, negatively. Since all the export commodities were positively impacted by GDP, increasing quality and quantity of the product of the commodities would bring a vital outcome for increasing the performance of the export of the commodities, which can be regarded as the key finding for the research.

description: Calculation of statistical properties of nuclei in a finite-temperature mean-field theory requires projection onto good particle number, since the theory is formulated in the grand canonical ensemble. This projection is usually carried out in a saddle-point approximation. Here we derive formulas for an exact particle-number projection of the finite-temperature mean-field solution. We consider both deformed nuclei, in which the pairing condensate is weak and the Hartree-Fock (HF) approximation is the appropriate mean-field theory, and nuclei with strong pairing condensates, in which the appropriate theory is the Hartree-Fock-Bogoliubov (HFB) approximation, a method that explicitly violates particle-number conservation. For the HFB approximation, we present a general projection formula for a condensate that is time-reversal invariant and a simpler formula for the Bardeen-Cooper-Schrieffer (BCS) limit, which is realized in nuclei with spherical condensates. We apply the method to three heavy nuclei: a typical deformed nucleus $^{162}$Dy, a typical spherical nucleus $^{148}$Sm, and a transitional nucleus $^{150}$Sm in which the pairing condensate is deformed. We compare the results of this projection with results from the saddle-point approximation and exact shell model Monte Carlo calculations. We find that the approximate canonical HF entropy in the particle-number projection decreases monotonically to zero in the limit when the temperature goes to zero. However, in a nucleus with a strong pairing condensate, the approximate canonical HFB entropy in the particle-number projection decreases monotonically to a negative value, reflecting the violation of particle-number conservation. Computationally, the exact particle-number projection is more efficient than calculating the derivatives required in the saddle-point approximation.

An Analysis Of The Macroeconomic Determinants Of Private Investment In Sierra Leone
Creators: name: Jalloh, Mohamed
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2002

description: This paper endeavors to identify the Macroeconomic determinants of private investment in Sierra Leone using time series data spanning from 1966 to 1998. From a simple trend analysis, it was observed that private investment (as a ratio of GDP) rose steadily from about 6.5% in 1966 to around 8.5% in 1978. After 1978, it fluctuated drastically reaching a minimum of around 3.8% in 1980 and subsequently shooting up to around 11.5% in 1981. Thereafter, private investment (as a ratio of GDP) decline continuously reaching a minimum of around 3.0% in 1998. Several reasons ranging from external shocks, inappropriate fiscal and monetary management, and the ten years of hostilities among others, were responsible for this. The methodology employed in carrying out the analysis of the study specified a version of the flexible accelerator model of investment for Sierra Leone following the works of Solimano (1990), Chhibber and Shafic (1990), Blejer and Khan (1984), Chhibber and Van Wijnbergen (1988), Musalem (1988), and Scmidt-Hebel and Muller (1991). A dummy variable taking the value of one from 1991 to1998 and zero otherwise, was used to take account of the war in Sierra Leone and enters the regression. This is followed by estimation techniques on the basis of Co-integration analysis using both the Johansen's (1988) procedure and the ECM approach. On the basis of the Johansen's procedure, a single cointegrating vector was identified. Both the long-run and a dynamic private investment models were subsequently estimated. From the estimates of the long-run model, the results indicated that while real GDP and public sector investment positively affect private investment, interest rate, real exchange rate and inflation negatively affect private investment. On the basis of the Short-run estimates, while public sector investment, real GDP and the interest rate have positive effect on private investment, inflation and the real exchange rate negative effects on private investment. Though not significant, the war dummy show a negative sign indicating the adverse effect of the war on private investment in Sierra Leone.

A strong dependence of the refraction angle and the optical beam spread on the exciton radiative lifetime is revealed. We demonstrate the strong negative refraction of light and the control of the group velocity of light by an external bias through its effect upon the exciton radiative properties.

description: The level of random motions in the intracluster gas lying between 20 and 60 kpc radius in the core of the Perseus cluster has been measured by the Hitomi Soft X-ray Spectrometer at 164 +/- 10 km/s. The maximum energy density in turbulent motions on that scale is therefore low. If dissipated as heat the turbulent energy will be radiated away in less than 80 Myr and cannot spread across the core. A higher velocity is needed to prevent a cooling collapse. Gravity waves are shown to travel too slowly in a radial direction. Here we investigate propagation of energy by sound waves. The energy travels at about 1000 km/s and can cross the core in a cooling time. We show that the displacement velocity amplitude of the gas required to carry the power is consistent with the Hitomi result and that the inferred density and temperature variations are consistent with Chandra observations.

description: The aim of this study is to determine the level of satisfaction of foreign customers on the service quality provided by five star hotels (Sheraton Addis, Hilton, and Intercontinental Hotels) in Ethiopia. Quantitative research method with descriptive method of analysis is employed to undertake the study. Demanded data was collected from foreign customers of the five star Ethiopian hotels which are selected randomly in their staying. Data quality and reliability of the study has been estimated and analyzed using both descriptive and inferences statistics via SPSS. Service quality model was used with its five dimensions of service quality tangibility, reliability, responsiveness, assurance, and empathy to estimate the level of foreign customers' expectation and perception of the hotels services. Questionnaires are designed in based on Likert scale developed from previous research models. The main findings are that of foreign customers are not satisfied by the services of the hotels, more over all services quality dimensions created a gap in their expectation and perception of guests. Hoteliers should understand the guests' expectations and standardize relevant services, periodically evaluate service quality and they should not exaggerated advertisements to increase the foreign customers' expectations

description: The isotropic majority-vote (MV) model which, apart from the one-dimensional case, is thought to be non-equilibrium and violating the detailed balance condition. We show that this is not true, when the model is defined on a complete graph. In the stationary regime, the MV model on a fully connected graph fulfills the detailed balance. We derive the exact expression for the probability distribution of finding the system in a given spin configuration. We show that it only depends on the absolute value of magnetization. Our theoretical predictions are validated by numerical simulations.

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2015

description: The study focused on the impact of corporate governance on Microfinance Institutions financial Performance in Ethiopia over a period of seven years from 2007/08-2013/14. The study was necessitated by the lack of documented literature on the impact of corporate governance on the financial performance of Microfinance institutions in Ethiopia. The main objective of the study was to investigate the impact of corporate governance on Ethiopian Microfinance institutions sustainability. The relevant literature was reviewed for the purposes of this study. Explanatory research design was used in trying to establish the causal effect relationship between corporate governance variable (which were; board size, board gender composition, board competency, board experience in the finance sector, meeting frequency of , size of audit committee, CEO duality, and CEO gender) and the control variable (size of MFI) was added. The financial performance measure was Return on Asset. 10 MFIs was selected as a sample from 35 licensed MFI from NBE. Primary data was captured using structured questionnaires completed by the CEOs as they were in a better position to comment on corporate governance affairs. Secondary data was collected from the NBE. The study utilized panel data analysis methodology in drawing conclusions about the study. It was foundthat the average board size was 6 members, the average board member who had college degree or higher was 7 member, average female director was 1, average annual meeting was 7 and average size of audit committee was 1 with 20 % of the institutions having the CEO double up as the board, 20% of the institutions surveyed had a female CEO. Empirical findings confirmed that board size, board competency, board experience in the financial sector and meeting frequency of board has a significant impact on the financial performance of Microfinance Institutions. However, size of audit committee has a significant negative relationship with the financial performance of Microfinance Institutions. Board gender composition, CEO duality and CEO gender does not have significant impact on the financial performance of Microfinance Institutions. Key terms:-Corporate governance, Financial Performance, ROA, MFIs, Ethiopia.

We discuss the feasibility of detecting this structure in J/psi photoproduction in the CLAS12 experiment at JLab. We present a first estimate of the upper limit for the branching ratio of the P_c(4450) to J/psi p. Our estimates, which take into account the experimental resolution effects, predict that it will be possible to observe a sizable cross section close to the J/psi production threshold and shed light on the P_c(4450) resonance in the future photoproduction measurements.

description: Cuprate materials, like those hosting high temperature superconductivity, represent a famous class of materials where the correlations between the strongly entangled charges and spins produce complex phase diagrams. Several years ago the Zhang-Rice singlet was proposed as a natural quasiparticle in hole-doped cuprates. The occurance and binding energy of this quasiparticle, consisting of a pair of bound holes with antiparallel spins on the same CuO$_4$ plaquette, depends on the local electronic interactions, which are fundamental quantities for understanding the physics of the cuprates. Here, we employ state-of-the-art Resonant Inelastic X-ray Scattering (RIXS) to probe the correlated physics of the CuO$_4$ plaquettes in the quasi-one dimensional chain cuprate Li$_2$CuO$_2$. By tuning the incoming photon energy to the O $K$-edge, we populate bound states related to the Zhang-Rice quasiparticles in the RIXS process. Both intra- and interchain Zhang-Rice singlets are observed and their occurrence is shown to depend on the nearest-neighbor spin-spin correlations, which are readily probed in this experiment. We also extract the binding energy of the Zhang-Rice singlet and identify the Zhang-Rice triplet excitation in the RIXS spectra.

Tests for Traditional Structure-Conduct-Performance Paradigm and the Efficient Market Hypothesis in the Ethiopian Banking Sector
Creators: name: Getahun, Eshetu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2006

description: This paper attempts to distinguish between the market structure paradigm and the efficiency paradigm using concentration indices and market share into the empirical analysis. Using panel data for the period 2000-2009 pertaining to eight private commercial banks, we find insignificant positive relationship between concentration and profitability. The result also does not suggest relationship between efficiency and profitability. Hence, the paper lends no credence to the impact of imperfections of market conditions as a result of concentration and market share. Moreover, evidence to argue for a more interventionist competition policy in the banking sector is less likely. Key words: Structure; profitability; efficiency; banks; concentration; panel econometrics.

description: In this paper, we study a physical system that is composed of massive charged scalar field linearly coupled to a charged rotating Kerr-Newman black hole. Given the parameters of black hole and a specific set of "quantum" numbers, the parameter space of the scalar field, which is a plane spanned by its mass and charge, is divided into five partitions by three simple constraint lines and the existence line of scalar clouds. The physical properties of the system in these partitions are presented. It is found that superradiant instability may be possibly caused only in two of the partitions. In particular, it is shown that both the mass and charge of the scalar clouds are bounded in a limited region. Our results may be used to rapidly judge the possible occurrence of superradiant instability and the existence of scalar clouds around a given black hole.

Determinants of Competition in the Commercial Banks of Ethiopia: An Empirical Evidence
Creators: name: Serawitu, Sarah
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: The development of a financial sector can very well be improved by enhancing the level of competition which can be achieved by improving the determinant factors. It is pertinent, therefore, to measure the level of competition and determine what factor affect the magnitude of the competition in the financial sector. This study provides an empirical evidence on the commercial banks of Ethiopia over the budget years, from 2000-2015. It measures the level of competition among the commercial banks of Ethiopia by taking a sample of the seven private commercial banks, i.e. Awash International Bank, Bank of Abyssinia, Dashen Bank, United Bank, Wegagen Bank and Nib International Bank, and Commercial bank of Ethiopia by using the Panzar-Rosse approach. I further tries to gauge what variable determine the level of competition in the commercial banks by using the contestability of market, financial liberation and economic factors. The results of the research show that the commercial banks of Ethiopia are in monopolistic competition which is a midway between perfect competition and monopoly; the market is in a long run equilibrium. The determinants of competition are found to have a joint statistically significant effect on the level of competition. The study suggest enhancing better access to financial services with in the country and also decrement of NBE's regulatory power. Key words; commercial bank competition, determinants

description: We extend previous results on healthy derivative self-interactions for a Proca field to the case of a set of massive vector fields. We obtain non-gauge invariant derivative self-interactions for the vector fields that maintain the appropriate number of propagating degrees of freedom. In view of the potential cosmological applications, we restrict to interactions with an internal rotational symmetry. We provide a systematical construction order by order in derivatives of the fields and making use of the antisymmetric Levi-Civita tensor. We then compare with the one single vector field case and show that the interactions can be broadly divided into two groups, namely the ones obtained from a direct extension of the generalized Proca terms and genuine multi-Proca interactions with no correspondence in the single Proca case. We also discuss the curved spacetime version of the interactions to include the necessary non-minimal couplings to gravity. Finally, we explore the cosmological applications and show that there are three different vector fields configurations giving rise to isotropic solutions. Two of them have already been considered in the literature and the third one, representing a combination of the first two, is new and offers unexplored cosmological scenarios.

description: In order to interpret recent experimental studies of the dependence of conductance of ds-DNA as the DNA is pulled from the 3'end1-3'end2 ends, which find a sharp conductance jump for a very short (4.5 %) stretching length, we carried out multiscale modeling, to predict the conductance of dsDNA as it is mechanically stretched to promote various structural polymorphisms. We calculate the current along the stretched DNA using a combination of molecular dynamics simulations, non-equilibrium pulling simulations, quantum mechanics calculations, and kinetic Monte Carlo simulations. For 5'end1-5'end2 attachments we find an abrupt jump in the current within a very short stretching length (6 $ Å$ or 17 %) leading to a melted DNA state. In contrast, for 3'end1-3'end2 pulling it takes almost 32$ Å$ (84 %) of stretching to cause a similar jump in the current. Thus, we demonstrate that charge transport in DNA can occur over stretching lengths of several nanometers. We find that this unexpected behaviour in the B to S conformational DNA transition arises from highly inclined base pair geometries that result from this pulling protocol. We find that the dramatically different conductance behaviors for two different pulling protocols arise from the nature of how hydrogen bonds of DNA base pairs break.

description: The growth and survival of any business organization depend on its customers. Customers are source of profit as well as the building block of maintaining market share of the company. The dominating feature of fierce competition in today's business and globalization required any companies to build long term relationship marketing with customers and to scale up customer loyalty. Therefore, currently relationship marketing has become vital instrument of business and existences. Dimensions of relationship marketing including customer services are the vital pivot point for attracting and retaining customers'. Therefore, this study is aimed to explore the role of relationship marketing in enhancing customer services and maintaining company's sustainable growth in the case of kk private ltd. Com. A theoretical framework was used as a guideline to show the interdependency of level of customer loyalty ladder, customer services and sustainable growth . Based on qualitative and quantitative method, descriptive research approach has been selected and carried out. Primary data was collected from internal sources by using semistructured interview and pre- designed research questionnaire which have given to all whole seller of the company. Secondary data was collected from the company sales report, marketing research report, and strategic plan documents. The population study are all whole seller who made a business with a company considered as sample size, there number is 60, of which 52 of them has responded to the questionaraire. Relationship marketing ladder of customer of Seth Godin with some modification is the pivot point of research analyses. A descriptive statistics accompanied with tables and percentages were in used to analyze the data. The finding of the study identified the current level customers' loyalty ladder and the customer service valued most by customers and additional service they will want to see in future. Similarly, the current relationships between customer and organization are assessed and its impact on sustainable growth of the KK private Ltd Com. is also indicated. Hence, the KK private Ltd Com has to work closely with current customer without any services discrimination and attract the new ones. Continuously improve the quality of customer service based on the research and try to establish a solid ground for long term customer relationships. Key words: Relationship Marketing, level of Customer Loyalty ladder and customer services.

description: The production of poultry, eggs and their processed products is growing rapidly worldwide. Poultry products are in great demand; however, they are a source of a number of risks: physical, chemical, as well as microbiological. Ensuring food safety is currently the main aspect for the global food industry, including for the production of poultry products. The article discusses the safety and quality of poultry products produced in subsidiary farms of correctional facilities of the penal system. Attention is drawn to the risks and threats of sanitary and epidemiological well-being that arise in connection with the intensification of the impact of negative environmental factors. In the subsidiary farms of correctional facilities, the cage-type bird keeping system and the frequency of feeding are regulated depending on the age of the bird. The results of the analysis have shown that poultry and chicken eggs comply with established sanitary standards. Thus, the average heavy metal content in poultry meat was: Hg - 0.0061 mg kg-1 , Cd - 0.0233 mg kg-1, As - 0.0501 mg kg-1, Pb - 0.1765 mg kg-1; in the egg: Hg - 0.0072 mg kg-1 , Cd - 0.0198 mg kg-1, As - 0.0485 mg kg-1, Pb - 0.1812 mg kg-1. Antibiotics, radionuclides and dioxins were not found in poultry meat. The pesticide content in poultry meat was below the permissible level: by 2.2 times of DTM and its metabolites, and hexachlorocyclohexane (a, b, g - isomers) - by 5 times. Coliforms, Staphylococcus aureus, Proteus, as well as pathogenic salmonella, listeria were not found in poultry meat and eggs. NMAFAnM in meat amounted to 0.5×104 , in the egg - 1×103 CFU g-1 incl. In general, poultry products produced in correctional facilities are of high enough quality and can be used to prepare various dishes not only for adults but also for baby food. These estimates allow us to conclude about a fairly high level of quality and safety of this product.

description: Communication activities aim to raise awareness about the general issues which our project is dealing with. These activities should have a broad range of audience, and start as soon as the project is defined. Dissemination activities are meant to spread the results of the project, they are closely linked to them, and must only interest the groups dealing with the same concerns. Hence, and in order to lead a successful dissemination campaign, we must identify this groups of interest or stakeholders, and tailor our message. This deliverable presents our previous work of stakeholders’ identification, as the data we have gathered during the first months of the project. We assume that it must be conceived as a basis, and be enriched all along the project’s life.

description: The morphology of young Pulsar Wind Nebulae (PWN) is largely determined by the properties of the wind injected by the pulsar. We have used a recent parametrization of the wind obtained from Force Free Electrodynamics simulations of pulsar magnetospheres to simulate nebulae for different sets of pulsar parameters. We performed axisymmetric Relativistic Magnetohydrodynamics simulations to test the morphology dependence of the nebula on the obliquity of the pulsar and on the magnetization of the pulsar wind. We compare these simulations to the morphology of the Vela and Crab PWN. We find that the morphology of Vela can be reproduced qualitatively if the pulsar obliquity angle is alpha ~45deg and the magnetization of the wind is high (sigma_0 ~ 3.0). A morphology similar to the one of the Crab Nebula is only obtained for low magnetization simulations with alpha >~ 45deg. Interestingly, we find that Kelvin-Helmholtz instabilities produce small scale turbulences downstream of the reverse shock of the pulsar wind.

description: We use the Balmer decrements of the broad-line regions (BLRs) and narrow-line regions (NLRs) of active galactic nuclei (AGNs) as reddening indicators to investigate the location of the dust for four samples of AGNs with reliable estimates of the NLR contribution to the Balmer lines. Intercomparison of the NLR and BLR Balmer decrements indicates that the reddening of the NLR sets a lower limit to the reddening of the BLR. Almost no objects have high NLR reddening but low BLR reddening. The reddening of the BLR is often substantially greater than the reddening of the NLR. The BLR reddening is correlated with the equivalent widths of [O III] lines and the intensity of the [O III] lines relative to broad Hβ. We find these relationships to be consistent with the predictions of a simple model where the additional dust reddening the BLR is interior to the NLR. We thus conclude that the dust causing the additional reddening of the accretion disc and BLR is mostly located at a smaller radius than the NLR.

Controlling the s-wave scattering length with non-resonant light: Predictions of an asymptotic model

description: A pair of atoms interacts with non-resonant light via its anisotropic polarizability. This effect can be used to tune the scattering properties of the atoms. Although the light-atom interaction varies with interatomic separation as $1/R^{3}$, the effective s-wave potential decreases more rapidly, as $1/R^{4}$ such that the field-dressed scattering length can be determined without any formal difficulty. The scattering dynamics are essentially governed by the long-range part of the interatomic interaction and can thus be accurately described by an asymptotic model [Crubellier et al., New J. Phys. 17, 045020 (2015)]. Here we use the asymptotic model to determine the field-dressed scattering length from the s-wave radial component of a particular threshold wave function. Applying our theory to the scattering of two strontium isotopes, we calculate the variation of the scattering length with the intensity of the non-resonant light. Moreover, we predict the intensities at which the scattering length becomes infinite for any pair of atoms.

description: Using time- and angle-resolved photoemission spectroscopy with selective near- and mid-infrared photon excitations, we investigate the femtosecond dynamics of the charge density wave (CDW) phase in 1$T$-TiSe$_2$, as well as the dynamics of CDW fluctuations at 240 K. In the CDW phase, we observe the coherent oscillation of the CDW amplitude mode. At 240 K, we single out an ultrafast component in the recovery of the CDW correlations, which we explain as the manifestation of electron-hole correlations. Our momentum-resolved study of femtosecond electron dynamics supports a mechanism for the CDW phase resulting from the cooperation between the interband Coulomb interaction, the mechanism of excitonic insulator phase formation, and electron-phonon coupling.
