Year: 2017

description: This study empirically examines the effect bank regulation on performance of private commercial banksin Ethiopia and interprets the result by relating with the regulations. The studyused balanced panel model in examining the regression model and collect data from sevenprivate commercial bankscovering the period of eleven (11)consecutive years, 2005- 2015. To this end, the study employed a quantitativeresearch approach by documentary analysis based on their audited financial statement. The study used one dependent variable return on asset (ROA), five independentvariables that are equity investment, legal reserve requirement, capital requirement, Capital adequacy and bank size.The regression result showedthat capital requirement and bank size had a positive and significant effect on profitability of private commercial banks. Capital adequacy and reserve requirement had negative and significant effect on profitability. Equity investment had negative but insignificant effect on performance of private commercial banks in Ethiopia. The research provides evidence of majorityvariables used to measurebank regulationhas an effect on profitability of Ethiopian private commercial banks. Hence, the study recommendsthat Ethiopian private commercial banks should give due attentionon bank regulationto enhance their profitability significantly.

description: The Strangeness ${\cal S}=-2$ J-PARC E07 emulsion experiment published recently two new $Ξ^-$--$^{14}$N capture events, IRRAWADDY and IBUKI, identified by observing weak-decay sequences of pairs of single-$Λ$ hypernuclei and interpreted as $Ξ^{-}_{1s}$ and $Ξ^{-}_{1p}$ nuclear bound states, respectively, with binding energies $B_{Ξ^-}^{1s}$=6.27$\pm$0.27 MeV and $B_{Ξ^-}^{1p}$=1.27$\pm$0.21 MeV. $Ξ^-$ capture events in emulsion play a major role in determining the $Ξ$-nuclear and the $ΛΛ$ potential strengths. Here we question the assignment of a $Ξ^{-}_{1s}$ nuclear bound state to IRRAWADDY and offer an alternative assignment as a near-threshold $Ξ^0_{1p}$--$^{14}$C nuclear bound state, slightly admixed with a $Ξ^{-}_{1p}$--$^{14}$N nuclear bound state component corresponding to IBUKI. We also question using IBUKI's $B_{Ξ^-}^{1p}$ value as is to determine the $Ξ$-nuclear potential depth. Altogether, $Ξ^-$ capture events in $^{12}$C and $^{16}$O should prove less ambiguous than in $^{14}$N.

description: The Gemini Planet Imager (GPI) has been designed for the direct detection and characterization of exoplanets and circumstellar disks. GPI is equipped with a dual channel polarimetry mode designed to take advantage of the inherently polarized light scattered off circumstellar material to further suppress the residual seeing halo left uncorrected by the adaptive optics. We explore how recent advances in data reduction techniques reduce systematics and improve the achievable contrast in polarimetry mode. In particular, we consider different flux extraction techniques when constructing datacubes from raw data, division by a polarized flat-field and a method for subtracting instrumental polarization. Using observations of unpolarized standard stars we find that GPI's instrumental polarization is consistent with being wavelength independent within our errors. In addition, we provide polarimetry contrast curves that demonstrate typical performance throughout the GPIES campaign.

Determinants of Capital Structure Decisions of the Construction Companies in Addis Ababa, Ethiopia
Creators: name: Belay, Netsanet
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: The company's capital structure is influenced by a number of factors, and several studies have been conducted to examine the factors that can affect the capital structure of companies in various countries. However, no such study has been conducted in Ethiopia, where majority of construction companies have no clear financing pattern. Thus, the factors affecting their capital structure are not clear and therefore, this study was conducted in order to fill this existing knowledge gap. In examining the determinants of capital structure of those construction companies, quantitative research approach is used. A panel data collected from 11 randomly selected construction companies, covering the period from 2006 to 2010 was used. The findings from the panel random effect estimation appear to support the pecking order theory of capital structure. Specifically, the result reveals that the variables including growth opportunity, tangibility, and non-debt tax shield positively affect the variations on the capital structure of construction companies. Profitability of the companies, size, earning volatility, liquidity and age, on the other hand, inversely affect their capital structure. Furthermore, among the whole independent variables, which are tested in this study, growth opportunity, tangibility of assets, liquidity and age of the company's are found as significant variables that explains the variations of the capital structure of construction companies.

description: We substantiate a covariant proposal for the holographic reflected entropy in $CFT$s dual to non-static $AdS$ geometries from the bulk extremal entanglement wedge cross section in the literature with explicit computations in the $AdS_3/CFT_2$ scenario. In this context we obtain the reflected entropy for zero and finite temperature time dependent bipartite mixed states in $CFT_{1+1}$s with a conserved charge dual to bulk rotating extremal and non-extremal BTZ black holes through a replica technique. Our results match exactly with the corresponding extremal entanglement wedge cross section for these bulk geometries in the literature. This constitutes a significant consistency check for the proposal and its possible extension to the corresponding higher dimensional $AdS/CFT$ scenario.

Dynamics of a single-atom electron pump

description: Single-electron pumps based on isolated impurity atoms have recently been experimentally demonstrated. In these devices the Coulomb potential of an atom creates a localised electron state with a large charging energy and considerable orbital level spacings, enabling robust charge capturing processes. In these single-atom pumps, the confinement potential is hardly affected by the periodic driving of the system. This is in contrast to the often used gate-defined quantum dot pumps, for which a strongly time-dependent potential leads to significantly different charge pumping processes. Here we describe the behaviour and the performance of an atomic, single parameter, electron pump. This is done by considering the loading, isolating and unloading of one electron at the time, on a phosphorous atom embedded in a silicon double gate transistor. The most important feature of the atom pump is its very isolated ground state, which can be populated through the fast loading of much higher lying excited states and a subsequent fast relaxation proces. This leads to a substantial increase in pumping accuracy, and is opposed to the adverse role of excited states as observed for quantum dot pumps due to non-adiabatic excitations. The pumping performances are investigated as a function of dopant position, revealing a pumping behaviour robust against the expected variability in atomic position.

description: There has been a recent upsurge of interest in the quantum properties of magnons for quantum information processing. An important issue is to examine the stability of quantum states of magnons against various relaxation and dephasing channels. Since the interaction of magnons in magnetic systems may fall in the ultra-strong and even deep-strong coupling regimes, the relaxation process of magnon states is quite different from the more common quantum optical systems. Here we study the relaxation and dephasing of magnons based on the Lindblad formalism and derive a generalized master equation that describes the quantum dynamics of magnons. Employing this master equation, we identify two distinct dissipation channels for squeezed magnons, i.e., the local dissipation and collective dissipation, which play a role for both ferromagnets and antiferromagnets. The local dissipation is caused by the independent exchange of angular momentum between the magnonic system and the environment, while the collective dissipation is dressed by the parametric interactions of magnons and it enhances the quantumness and thermal stability of squeezed magnons. Further, we show how this formalism can be applied to study the pure dephasing of magnons caused by four-magnon scattering and magnon-phonon interactions. Our results provide the theoretical tools to study the decoherence of magnons within a full quantum-mechanical framework and further benefit the use of quantum states of magnons for information processing.

Assessment of Perceptions of Shareholders Towards the Benefits of Investing in Shares: the Case of Awash International Bank S.C.
Creators: name: Birhanu, Kibru
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2009

description: The main focus of this paper is assessing the perception of shareholders towards the benefits of investing in shares. A questionnaire was answered by 86 respondents in Awash International Bank S.C. The sample of this study is relatively heterogeneous, which allows the researcher to have an overview of the perceptions and behavioral tendencies of a variety of shareholder groups in setting objectives, risk-taking, and in understanding the benefits of investing in shares. The majority of shareholders have long-term objectives and in general high risk taking tendencies were observed. In risk- taking, there is a significant difference between gender and among age categories. The findings suggest that the shareholders have inadequate knowledge of the benefits to be realized in relation to investing in shares. The problem spreads across a broad spectrum of shareholders of various categories, both genders, and different academic disciplines. Consistent with previous studies, the results have shown that female shareholders are less knowledgeable about the benefits than male shareholders; non-business majors are less knowledgeable than business majors, and institutional shareholders have better understanding than either individual or joint shareholders. The differences between these groups are statistically significant. The secondary data analysis also supports the hypotheses constructed. On the other hand, the corporate governance practices of the bank in protecting the rights of shareholders are collectively encouraging. Generally, the findings suggest that low awareness levels of the benefits of investing in shares exist among shareholders and the issue needs to be addressed

description: Developing successful scaffolds requires clinicians to adopt a multidisciplinary approach in order to understand and stimulate the natural bone regeneration process. A variety of natural and synthetic biomaterials, including naturally extracted, chemically functionalised collagen and synthetic Poly(epsilon-caprolactone) (PCL), can be manufactured into fibres, enabling the formation of nonwoven scaffolds. Many different nonwoven architectures and structural features can then be introduced, depending on the manufacturing parameters. This chapter introduces methods for producing scaffolds with appropriate pore sizes by means of electrospinning, and it outlines the opportunities that exist for other nonwoven manufacturing technologies in the development of biomimetic products.

description: Dynamic symbolic execution (DSE) is an effective method for automated program testing and bug detection. It is increasing the code coverage by the complex branches exploration during hybrid fuzzing. DSE tools invert the branches along some execution path and help fuzzer examine previously unavailable program parts. DSE often faces over- and underconstraint problems. The first one leads to significant analysis complication while the second one causes inaccurate symbolic execution. We propose strong optimistic solving method that eliminates irrelevant path predicate constraints for target branch inversion. We eliminate such symbolic constraints that the target branch is not control dependent on. Moreover, we separately handle symbolic branches that have nested control transfer instructions that pass control beyond the parent branch scope, e.g. return, goto, break, etc. We implement the proposed method in our dynamic symbolic execution tool Sydr. We evaluate the strong optimistic strategy, the optimistic strategy that contains only the last constraint negation, and their combination. The results show that the strategies combination helps increase either the code coverage or the average number of correctly inverted branches per one minute. It is optimal to apply both strategies together in contrast with other configurations.

description: In this work, we address the problem of channel estimation and precoding / combining for the so-called hybrid millimeter wave (mmWave) MIMO architecture. Our proposed channel estimation scheme exploits channel reciprocity in TDD MIMO systems, by using echoing, thereby allowing us to implement Krylov subspace methods in a fully distributed way. The latter results in estimating the right (resp. left) singular subspace of the channel at the transmitter (resp. receiver). Moreover, we also tackle the problem of subspace decomposition whereby the estimated right (resp. left) singular subspaces are approximated by a cascade of analog and digital precoder (resp. combiner), using an iterative method. Finally we compare our scheme with an equivalent fully digital case and conclude that a relatively similar performance can be achieved, however, with a drastically reduced number of RF chains - 4 ~ 8 times less (i.e., massive savings in cost and power consumption).

description: BACKGROUND: Random-effects meta-analysis within a hierarchical normal modeling framework is commonly implemented in a wide range of evidence synthesis applications. More general problems may even be tackled when considering meta-regression approaches that in addition allow for the inclusion of study-level covariables. METHODS: We describe the Bayesian meta-regression implementation provided in the bayesmeta R package including the choice of priors, and we illustrate its practical use. RESULTS: A wide range of example applications are given, such as binary and continuous covariables, subgroup analysis, indirect comparisons, and model selection. Example R code is provided. CONCLUSIONS: The bayesmeta package provides a flexible implementation. Due to the avoidance of MCMC methods, computations are fast and reproducible, facilitating quick sensitivity checks or large-scale simulation studies.

Possibility of Syndicate Lending in Ethiopia Banking Industry. (Case of selected eight banks).
Creators: name: Mekonnen, Tekalign
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: There is a considerable expansion of the volume of syndicated loans in emerging markets in the recent years. While until recently large majority of loan transactions in Ethiopia historically have been bilateral transactions that are provided by single banks. This thesis empirically investigates factors that influence the possibility of syndicate lending in Ethiopia banking industry using the financial information of 8 banks for the period of 2005-2010. The study investigate significant role of loan characteristics and of lending limit, liquidity, capital adequacy and concentration on the possibility of syndicate lending on Ethiopia banking industry. The result of the study indicates that lending limit and liquidity positively influences the possibility of syndicate lending in Ethiopia banking industry while capital adequacy and concentration negatively influences. This shows Banks does not join loan syndications when their capital levels are sufficient enough to support the extra risk taken. The results of the study also support the efforts of authorities to increase banking competition and efficiency, and to implement binding banking regulation on capital requirement to promote the possibility of syndicated loan

description: The spectral and localization properties of heterogeneous random graphs are determined by the resolvent distributional equations, which have so far resisted an analytic treatment. We solve analytically the resolvent equations of random graphs with an arbitrary degree distribution in the high-connectivity limit, from which we perform a thorough analysis of the impact of degree fluctuations on the spectral density, the inverse participation ratio, and the distribution of the local density of states. We show that all eigenvectors are extended and that the spectral density exhibits a logarithmic or a power-law divergence when the variance of the degree distribution is large enough. We elucidate this singular behaviour by showing that the distribution of the local density of states at the center of the spectrum displays a power-law tail determined by the variance of the degree distribution. In the regime of weak degree fluctuations the spectral density has a finite support, which promotes the stability of large complex systems on random graphs.

Planet detection down to a few $λ$/D: an RSDI/TLOCI approach to PSF subtraction
Creators: name: Gerard, Benjamin L.

Publisher: name: arXiv
Year: 2016
Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)
subject: FOS: Physical sciences

description: Most current high contrast imaging point spread function (PSF) subtraction algorithms use some form of a least-squares noise minimization to find exoplanets that are, before post-processing, often hidden below the instrumental speckle noise. In the current standard PSF subtraction algorithms, a set of reference images is derived from the target image sequence to subtract each target image, using Angular and/or Simultaneous Spectral Differential Imaging (ADI, SSDI, respectively). However, to avoid excessive exoplanet self-subtraction, ADI and SSDI (in the absence of a strong spectral feature) severely limit the available number of reference images at small separations. This limits the performance of the least-squares algorithm, resulting in lower sensitivity to exoplanets at small angular separations. Possible solutions are to use additional reference images by acquiring longer sequences, use SSDI if the exoplanet is expected to show strong spectral features, or use images acquired on other targets. The latter option, known as Reference Star Differential Imaging (RSDI), which relies on the use of reference images that are highly correlated to the target image, has been ineffective in previous ground-based high contrast imaging surveys. We present the results of work to optimize PSF subtraction with the GPIES reference library using a least-squares algorithm designed to minimize speckle noise and maximize planet throughput, thus maximizing the planet signal to noise ratio (SNR). Using December 2014 51 Eri GPI data in the inner 100 mas to 300 mas annulus, we find no apparent improvement in SNR when using RSDI and/or our optimization scheme. This result, while still being investigated, seems to show that current algorithms on ADI+SSDI data sets are optimized, and that limited gains can be achieved by using a PSF archive.

description: A system can be driven between metastable configurations by a time-dependent driving protocol, which uses external control parameters to change the potential energy of the system. Here we investigate the correspondence between driving protocols that are designed to minimize work and the spontaneous transition paths of the system in the absence of driving. We study the spin-inversion reaction in a 2D Ising model, quantifying the timing of each spin flip and heat flow to the system during both a minimum-work protocol and a spontaneous transition. The general order of spin flips during the transition mechanism is preserved between the processes, despite the coarseness of control parameters that are unable to reproduce more detailed features of the spontaneous mechanism. Additionally, external control parameters provide energy to each system component to compensate changes in internal energy, showing how control parameters are tuned during a minimum-work protocol to counteract underlying energetic features. This study supports a correspondence between minimum-work protocols and spontaneous transition mechanisms.

Year: 2016

description: This thesis aims to examine the Roles of E-banking on Financial Performance of Commercial Banks in Ethiopia. A successful bank in presenting good services to clients and gaining profit is the one using new banking tools. The study has examined the roles of e-banking on return on assets as one of the most fundamental indexes of profitability. The study used secondary data employed purposive sampling technique to select ten banks for the study commercial banks operating in Ethiopia covering the periods from 2013 to 2015. In light of prior literature, key explanatory variables were identified to disclose their relationship and influence on financial performance of commercial banks. These independent and other control variables are value or price of transaction of ATM, value or price of transaction of POS, debit card, number of automated teller machine terminals, number of point of sale terminal and market share of banks. Result using random effect panel least square regression with the aid of E-view 8 application exhibited that numbers of ATM terminals, number of POS terminals and bank market share have positive and significant role on financial performance of commercial banks measured by return on asset. The study shows that increased number of ATM, POS and market share had a positive role on the financial performance of commercial banks with many banking institutions indicating that increased market share allowed a company to achieve greater scale in its operations which generally improved its profitability. Therefore, this study recommends for enhancing return on asset commercial banks should exert more on awareness creation about e-banking service and timely support for users will cause an increase in e-banking practice in Ethiopia.

description: The relationships between quantum entangled states and braid matrices have been well studied in recent years. However, most of the results are based on qubits. In this paper, We investigate the applications of 2-qutrit entanglement in the braiding associated with $\mathbb{Z}_3$ parafermion. The 2-qutrit entangled state $|Ψ(θ)\rangle$, generated by acting the localized unitary solution $\breve{R}(θ)$ of YBE on 2-qutrit natural basis, achieves its maximal $\ell_1$-norm and maximal von Neumann entropy simultaneously at $θ=π/3$. Meanwhile, at $θ=π/3$, the solutions of YBE reduces braid matrices, which implies the role of $\ell_1$-norm and entropy plays in determining real physical quantities. On the other hand, we give a new realization of 4-anyon topological basis by qutrit entangled states, then the $9\times9$ localized braid representation in 4-qutrit tensor product space $(\mathbb{C}^3)^{\otimes 4}$ are reduced to Jones representation of braiding in the 4-anyon topological basis. Hence, we conclude that the entangled states are powerful tools in analysing the characteristics of braiding and $\breve{R}$-matrix.

description: Being able to abstract relations of similarity is considered one of the hallmarks of human cognition. While previous research has shown that other animals (e.g. primates) can attend to relational similarity, they struggle to focus on object similarity. This is in contrast with humans. And it is precisely the ability to attend to objects that it is argued to make relational reasoning uniquely human. What about invertebrates? Despite earlier studies indicating that bees are capable of learning abstract relationships (e.g. ‘same’ and ‘different’), no research has investigated whether bees can spontaneously attend to relational similarity and whether they can do so when relational matches compete with object matches. To test this, a spatial matching task (with and without competing object matches) previously used with children and great apes was adapted for use with wild-caught bumblebees. When objects matches were not present, bumblebees spontaneously used relational similarity. Importantly, when competing object matches were present, bumblebees still focused on relations over objects. These findings indicate that the absence of object bias is also present in invertebrates and suggest that the relational gap between humans and other animals is due to their preference for relations over objects.

description: We present improvements to the wavelength calibration for the lenslet-based Integral Field Spectrograph (IFS), that serves as the science instrument for the Gemini Planet Imager (GPI). The GPI IFS features a 2.7" $\times$ 2.7" field of view and a 190 $\times$ 190 lenslet array (14.1 mas/lenslet) with spectral resolving power ranging from R $\sim$ 35 to 78. A unique wavelength solution is determined for each lenslet characterized by a two-dimensional position, an n-dimensional polynomial describing the spectral dispersion, and the rotation of the spectrum with respect to the detector axis. We investigate the non-linearity of the spectral dispersion across all Y, J, H, and K bands through both on-sky arc lamp images and simulated IFS images using a model of the optical path. Additionally, the 10-hole non-redundant masking mode on GPI provides an alternative measure of wavelength dispersion within a datacube by cross-correlating reference PSFs with science images. This approach can be used to confirm deviations from linear dispersion in the reduced datacubes. We find that the inclusion of a quadratic term provides a factor of 10 improvement in wavelength solution accuracy over the linear solution and is necessary to achieve uncertainties of a few hundredths of a pixel in J band to a few thousands of a pixel in the K bands. This corresponds to a wavelength uncertainty of $\sim$0.2 nm across all filters.

description: Professional ethics and independence of an auditor has been considered as one of the main elements for the auditing environment and auditing professional bodies like the International Federation of Accountants (IFAC,),. The main objective of this study is to examine the current status of private audit firms' professional ethics and independence and its overall impact on the quality of audit service provided to the public on 20 private audit firms selected based on stratified random sampling technique. The study used descriptive statistics to analyze the collected primary and secondary data using SPSS. The results of the research result indicate that most of the private audit firms do not comply with professional ethics and lack independence from their client. This non-compliance came from self-interest, self-review and familiarity threats which results from lower audit fee, poor client assessment before accepting new engagements, having family, financial and personal relationship with their clients. Moreover inactive and dormant contribution of the regulatory and professional association respectively also are other factors that contribute for unethical practice, lack of independence and lower audit quality provided by private audit firm. The study recommend private audit firms should provide their professional services to the public in compliance with the rules and regulations stated by the regulatory bodies, Accounting and Auditing Board of Ethiopia should prepare a well-organized code of professional conduct and ethics that strictly applied by all private audit, regulatory and professional bodies should set strong audit quality control, high standard audit practices and enforce all audit and other constructive recommendation stated under researcher paper
Displacement: Neoliberal Land Warfare and Points of Intervention
Creators: name: Dobrowski, Jordan
Publisher: name: Unknown
Year: 2018

description: This paper draws upon existing literature to describe the dynamics of displacing peoples from their land and the intergenerational, sociological effects that follow. It presents cases from two regions of the world–the United States and India—where rural and tribal occupants have come into conflict within federal regimes in what many scholars are calling “land wars.” Both countries share a history of British colonial heritage which has provided a legal framework for land reallocation for national gain, and similarly both have since been heavily influenced by neoliberal economic values. The two examples serve to complement one another as tools for learning what interventions are possible for settling long-standing land disputes.
Ideología(s) lingüística(s): el caso del voseo

description: El voseo es un rasgo lingüístico, actualmente exclusivo de Hispanoamérica, que ha estado sujeto a lo largo del tiempo a diferentes valoraciones. A través de un estudio que combina criterios cuantitativos y cualitativos, el artículo toma en consideración las ideologías lingüísticas subyacentes a los comentarios relativos al uso del voseo en la red social Twitter, llevando a cabo una clasificación de los aspectos que entran en juego a la hora de valorar el fenómeno y las correspondientes connotaciones ideológicas: el papel de las autoridades lingüísticas, la relación entre voseo e identidad, los usos estigmatizados del voseo y la analogía entre el voseo y el lenguaje inclusivo.

description: Reversible Data Hiding in Encrypted Domain (RDHED) is an innovative method that can keep cover information secret and allows the data hider to insert additional information into it. This article presents a novel data hiding technique in an encrypted text called Reversible Data Hiding in Encrypted Text (RDHET). Initially, the original text is converted into their ASCII values. After that, the Paillier cryptosystem is adopted to encrypt all ASCII values of the original text and send it to the data hider for further processing. At the data hiding phase, the secret data are embedded into homomorphically encrypted text using a technique that does not lose any information, i.e., the homomorphic properties of the Paillier cryptosystem. Finally, the embedded secret data and the original text are recovered at the receiving end without any loss. Experimental results show that the proposed scheme is vital in the context of encrypted text processing at cloud-based services. Moreover, the scheme works well, especially for the embedding phase, text recovery, and performance on different security key sizes.

description: Muon tomography (MT), based on atmospheric cosmic rays, is a promising technique suitable for nondestructive imaging of the internal structures of mountains. This method uses the measured flux distribution after attenuation, combined with the known muon angular and energy distributions and a 3D satellite map, to perform tomographic imaging of the density distribution inside a probed volume. A muon tomography station (MTS) requires direction-sensitive detectors with a high resolution for optimal tracking of incident cosmic-ray muons. The spherical liquid scintillator detector is one of the best candidates for this application due to its uniform detection efficiency for the whole $4π$ solid angle and its excellent ability to distinguish muon signals from the radioactive background via the difference in the energy deposit. This type of detector, with a 1.3~m diameter, was used in the Jinping Neutrino Experiment~(JNE). Its angular resolution is 4.9~degrees. Following the application of imaging for structures of Jinping Mountain with JNE published results based on the detector, we apply it to geological prospecting. For mountains below 1~km in height and 2.8~${\rm g}/{\rm cm}^3$ in the reference rock, we demonstrate that this kind of detector can image internal regions with densities of $\leq$ 2.1~${\rm g}/{\rm cm}^3$ or $\geq$ 3.5~${\rm g}/{\rm cm}^3$ and hundreds of meters in size.

description: We propose an entropic measure of non-classical correlations in general mixed states of fermion systems, based on the loss of information due to the unread measurement of the occupancy of single particle states of a given basis. When minimized over all possible single particle bases, the measure reduces to an entanglement entropy for pure states and vanishes only for states which are diagonal in a Slater determinant basis. The approach is also suitable for states having definite number parity yet not necessarily a fixed particle number, in which case the minimization can be extended to all bases related through a Bogoliubov transformation if quasiparticle mode measurements are also considered. General stationary conditions for determining the optimizing basis are derived. For a mixture of a general pure state with the maximally mixed state, a general analytic evaluation of the present measure and optimizing basis is provided, which shows that non-entangled mixed states may nonetheless exhibit a non-zero information loss.

description: We investigate the adiabatic evolution of thermal state in non-reciprocal many-body systems coupled to their environment and subject to periodic drivings. In such systems we show that besides the dynamical phase a geometrical phase can exist and it drives the relaxation dynamic of the system. On the contrary to the dynamical phase which always pushes the system toward its equilibrium state we show that the geometric phase can speed up or reduce the speed of relaxation process. These results could have applications in the field of thermal management of complex systems.
