Subjects: CHIM/07 Fondamenti chimici delle tecnologie

description: Regenerative medicine and tissue engineering attempt to repair or improve the biological functions of tissues that have been damaged or have ceased to perform their role through three main components: a biocompatible scaffold, cellular component and bioactive molecules. Nanotechnology provide a toolbox of innovative scaffold fabrication procedures in regenerative medicine. In fact, nanotechnology, using manufacturing techniques such as conventional and unconventional lithography, allows fabricating supports with different geometries and sizes as well as displaying physical chemical properties tunable over different length scales. Soft lithography techniques allow to functionalize the support by specific molecules that promote adhesion and control the growth of cells. Understanding cell response to scaffold, and viceversa, is a key issue; here we show our investigation of the essential features required for improving the cell-surface interaction over different scale lengths. 
The main goal of this thesis has been to devise a nanotechnology-based strategy for the fabrication of scaffolds for tissue regeneration. We made four types of scaffolds, which are able to accurately control cell adhesion and proliferation. For each scaffold, we chose properly designed materials, fabrication and characterization techniques.
title: Application of Multivariate Analysis in Predicting Water Yields in Utah
Creators: name: Wang, Leei-Luoh
Publisher: name: Utah State University
Year: 1967

description: The basic hydrologic data required to determine the water yield are usually unavailable for small basins and streams while increasing emphasis is being placed on their development. Therefore, some methods and techniques for estimating the amount of water available for development of these small units is needed .
The purpose of this study is to use the concepts and techniques of statistical analysis to develop equations which are useful in estimating the water yield of watersheds for which no stream flow records are available . The approach is an extension of earlier studies at Utah State University (1, lQ) in which physiographic and topographic parameters were related to mean annual runoff of Utah watersheds. Previous studies used multiple regression techniques primarily . The work reported herein utilizes the same data as in the earlier work but analysis is based on the multivariate technique of principal component analysis. Results and evaluations derived from the principal component analysis are compared with those obtained from multiple regression analysis.

description: It has been interesting to note the development of the instrumental program in Utah in the past twenty-five years. Instrumentalists are in demand for a great number of organizations which perform in various capacities from the sports spectaculars to symphonic band and orchestras. Furthermore, the personnel of these groups are usually trained as soloists.
Much of this improvement has been due to the efforts of dedicated musicians, teachers who are affiliated with institutions of higher learning. They have marshalled the resources of the colleges and universities to upgrade the level of music education. They have trained people to train others in the schools and communities of this state.
Leaders in the past effort to upgrade skill with instrumental music have contended that an instrumental music educator should become more proficient on his major instrument and should learn, or at least try, to perform on other instruments which are used in his group. He will be a more effective teacher if he can demonstrate mastery of the problems involved.
His major professor invited the author of this study to accept the theory of multiple instrument mastery, to prepare and present an instrumental recital, and to submit a written report in lieu of a thesis study.
With rather dubious eagerness, the author accepted the challenge (assignment) and projected a program of working toward a recital. In addition to planning the solo performance, which included the selection of music, selecting a date that allowed -ample time in which to prepare, and reserving the hall where it would be performed, there was the problem of making sure that all the equipment was in the best mechanical condition.
Following is a report of the problems and experiences in achieving the directive and an appraisal of the project.
Quantum homotopy perturbation method for nonlinear dissipative ordinary differential equations

description: While quantum computing provides an exponential advantage in solving linear differential equations, there are relatively few quantum algorithms for solving nonlinear differential equations. In our work, based on the homotopy perturbation method, we propose a quantum algorithm for solving $n$-dimensional nonlinear dissipative ordinary differential equations (ODEs). Our algorithm first converts the original nonlinear ODEs into the other nonlinear ODEs which can be embedded into finite-dimensional linear ODEs. Then we solve the embedded linear ODEs with quantum linear ODEs algorithm and obtain a state $ε$-close to the normalized exact solution of the original nonlinear ODEs with success probability $Ω(1)$. The complexity of our algorithm is $O(gηT{\rm poly}(\log(nT/ε)))$, where $η$, $g$ measure the decay of the solution. Our algorithm provides exponential improvement over the best classical algorithms or previous quantum algorithms in $n$ or $ε$.

description: It is traditional in a master's recital for violin to include representative works from the Baroque, Classical, Romantic and/or Modern periods. Further, it is customary that the Baroque selection be one of the unaccompanied Bach sonatas or partitas . The program selected in this graduate recital conforms to these standards and to the recommendations of my violin professor, Mr . Richard G. Strawn.
To understand these customs that have developed for violin master'• recitals, it is important to consider the violin literature to see how the forms have varied in the different historical periods. Each new form has brought new technical and musical difficulties to be mastered.

description: Relativistic jets from AGN have a wide range of impacts on galaxy groups and clusters and are key for understanding their formation and physical properties. However, this non-gravitational process is not well understood. Galaxy groups with shallow gravitational potentials are ideal laboratories to study and constrain the AGN feedback model. We studied hot gas in ~66,000 SDSS LRG halos with an average halo mass of 3 x 10^13 Msun using the Planck tSZ map. We have detected their average tSZ radial profile at ~17 sigma and compared it with the cosmo-OWLS cosmological hydrodynamical simulations with different AGN feedback models. The best agreement has been obtained for the AGN 8.0 model in the simulations. We have also compared our measured tSZ profile with the prediction from the universal pressure profile assuming the self-similar relation and found them consistent if the model accounts for the clustering of neighboring haloes via a two-halo term.

description: When a core-collapse supernova explodes in a binary star system, the ejecta might encounter an overdense shell, where the stellar winds of the two stars previously collided. In this work, we investigate effects of such interactions on supernova light curves on time-scales from the early flash ionization signatures to approximately one year after the explosion. We construct a model of the colliding-wind shell in an orbiting binary star system and we provide an analytical expression for the shell thickness and density, which we calibrate with three-dimensional adaptive mesh refinement hydrodynamical simulations probing different ratios of wind momenta and different regimes of radiative cooling efficiency. We model the angle-dependent interaction of supernova ejecta with the circumstellar medium and estimate the shock radiative efficiency with a realistic cooling function. We find that the radiated shock power exceeds typical Type IIP supernova luminosity only for double red supergiant binaries with mass ratios $q \gtrsim 0.9$, wind mass-loss rates $\dot{M} \gtrsim 10^{-4} M_\odot\,\text{yr}^{-1}$, and separations between about 50 and 1500 AU. The required $\dot{M}$ increases for binaries with smaller $q$ or primaries with faster wind. We estimate that $\ll 1\%$ of all collapsing massive stars satisfy the conditions on binary mass ratio and separation. Recombination luminosities due to colliding wind shells are at most a factor of 10 higher than for an otherwise unperturbed constant-velocity wind, but higher densities associated with wind acceleration close to the star provide much stronger signal.

Configuration entropy and confinement-deconfinement transition in higher-dimensional hard wall model

description: We consider a higher-dimensional hard wall model with an infrared (IR) cut-off in asymptotically AdS space and investigate its thermodynamics via the holographic renormalization method. We find a relation between the confinement temperature and the IR cut-off for any dimension. It is also shown that the entropy of $p$-branes with the number of coincident branes (the number of the gauge group) $N$ jumps from leading order in $\cal O$($N^0$) at the confining low temperature phase to $\cal O$($N^{\frac{p+1}{2}}$) at the deconfining high temperature phase like $D3$-branes ($p=3$) case. On the other hand, we calculate the configuration entropy (CE) of various magnitudes of an inverse temperature at an given IR cut-off scale. It is shown that as the inverse temperature grows up, the CE above the critical temperature decreases and AdS black hole (BH) is stable while it below the critical temperature is constant and thermal AdS (ThAdS) is stable. In particular, we also find that the CE below the critical temperature becomes constant and its magnitude increases as a dimension of AdS space increases.

Revisiting quark-hadron duality for heavy meson non-leptonic decays in two-dimensional QCD

description: We study lifetimes of heavy mesons in the 't Hooft model, a large-$N_c$ theory of strong interaction in two-dimensional spacetime. Since this model is solvable, one can evaluate the total decay widths through hadronic amplitudes that are determined unambiguously within the formalism. We investigate quark-hadron duality by numerically comparing the exclusive result and one from the heavy quark expansion, with the contribution of Pauli interference being consistently incorporated. Within certain numerical accuracy, we find that the maximal difference between inclusive and exclusive rates for $τ[D^+_s]/τ[D^0]$ $(τ[B^+]/τ[B^0])$ is as large as the current experimental (theoretical) error in four-dimensions, except for $τ[D^+]/τ[D^0]$, where an excellent agreement between the rates is seen.

description: In this paper, we investigate thermodynamics and phase transitions of a 4-dimensional rotating Kaluza-Klein black hole solution in the presence of Maxwell electrodynamics. Calculating the conserved and thermodynamical quantities shows that the first law of thermodynamics is satisfied. To find the stable black hole' s criteria, we check the stability in the canonical ensemble by analyzing the behavior of the heat capacity. We also consider a massive scalar perturbation minimally coupled to the background geometry of the 4-dimensional static Kaluza-Klein black hole and investigate the quasinormal modes by employing the WKB approximation. The anomalous decay rate of the quasinormal modes spectrum is investigated by using the sixth-order WKB formula and quasi-resonance modes of the black hole are studied with averaging of Pade approximations as well.

Subprocesses $ρ(770,1450)\to K\bar{K}$ for the three-body hadronic $D$ meson decays

description: We construct the theoretical framework for quasi-two-body $D$ meson decays with the help of pion and kaon electromagnetic form factors, and with which we study the contributions of the subprocesses $ρ(770,1450)\to K\bar{K}$ for the three-body $D$ decays within the flavour $SU(3)$ symmetry. Because of the limitations imposed by phase space and strong coupling, the contributions for kaon pair from the virtual bound state $ρ(770)$ are channel-dependent and generally small for the concerned three-body $D$ decays. But some quasi-two-body processes could still be observed in the Dalitz plot analyses for related decays, such as $D^0 \to K^-ρ(770)^+ \to K^- K^+K_S^0$ and $D^+ \to K_S^0ρ(770)^+ \to K_S^0 K^+K_S^0$, they are predicted to have the branching fractions $\mathcal{B}=(0.82\pm0.04)\times 10^{-4}$ and $\mathcal{B}=0.47^{+0.05}_{-0.03}\times 10^{-4}$, which are $(1.86\pm0.16)\%$ and $(1.84^{+0.21}_{-0.16})\%$, respectively, of the total branching fractions for the corresponding three-body $D$ decays. We find in this work that the normal subprocesses like $ρ(1450)^+\to π^+π^0$ or $ρ(1450)^+\to K^+\bar{K}^0$, which are bound by the masses of decaying initial states, will provide virtual contributions in some special decays.

For particular values of parameters, they can be presented in closed-form. In most reported cases, these new integral functions are expressed as generalized hypergeometric functions but also in terms of elementary and special functions. The behavior of some of the new integral functions is presented in graphical form. By using the MATHEMATICA program to obtain infinite sums that define the Mittag-Leffler, Whittaker, and Wright functions and also their corresponding integral functions, these functions and many new Laplace transforms of them are also reported in the Appendices for integral and fractional values of parameters.

description: Sensing and communication circuits and systems are crucial components in various electronic devices and technologies. These systems are designed to acquire information from the surrounding environment through sensors, process that information, and facilitate communication between different devices or systems. It plays a vital role in modern electronic devices, enabling them to collect, process, and exchange information to perform various functions in applications such as IoB (Internet of Body), healthcare, hardware security, industrial automation, and more.This work focuses on innovations in sensing and communication circuits spanning two independent application areas – human body communication and hardware emanations security.First, an ultra-low power ECG monitoring system is implemented to perpetually power itself using Thermoelectric Generator (TEG) to harvest body energy while securely transmitting sensed data through on-body communication, achieving closed-loop operation without external charging or batteries. Custom circuits allow demonstrated feasibility of self-sustaining wearables leveraging Human Body Communication’s advantages.Second, investigations reveal vulnerabilities introduced when repairing broken cables, with unintended monopole antennas boosting electromagnetic emissions containing signal correlations. Experiments characterize long-range detection regimes post-repair across USB keyboard cables. Further circuit and structural innovations provide localized shielding at repair points as a potential mitigation. Advancements offer contributions in understanding hardware emission security risks to inform protection strategies.The two separate research work demonstrate specialized circuits advancing the state-of-the-art in sensing and communication for wearable body-based systems and hardware security through greater awareness of vulnerabilities from unintended emissions.

Bottling the Champagne: Dynamics and Radiation Trapping of Wind-Driven Bubbles around Massive Stars

Year: 2021
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: In this paper we make predictions for the behaviour of wind bubbles around young massive stars using analytic theory. We do this in order to determine why there is a discrepancy between theoretical models that predict that winds should play a secondary role to photoionisation in the dynamics of HII regions, and observations of young HII regions that seem to suggest a driving role for winds. In particular, regions such as M42 in Orion have neutral hydrogen shells, suggesting that the ionising radiation is trapped closer to the star. We first derive formulae for wind bubble evolution in non-uniform density fields, focusing on singular isothermal sphere density fields with a power law index of -2. We find that a classical "Weaver"-like expansion velocity becomes constant in such a density distribution. We then calculate the structure of the photoionised shell around such wind bubbles, and determine at what point the mass in the shell cannot absorb all of the ionising photons emitted by the star, causing an "overflow" of ionising radiation. We also estimate perturbations from cooling, gravity, magnetic fields and instabilities, all of which we argue are secondary effects for the conditions studied here. Our wind-driven model provides a consistent explanation for the behaviour of M42 to within the errors given by observational studies. We find that in relatively denser molecular cloud environments \around single young stellar sources, champagne flows are unlikely until the wind shell breaks up due to turbulence or clumping in the cloud.

We give the results for the most complicated box diagram both for gluon bilocal operators with arbitrary indices, and for combinations of indices corresponding to three matrix elements that are most convenient to extract the twist-2 invariant amplitude. We also present detailed results for the gluon-quark transition diagram. The additional results for the box diagram and the gluon-quark contribution may be used for extractions of the gluon PDF from different matrix elements, with a possible cross-check of the results obtained in this way.

The rise and fall of the United Housing Foundation : a case study of a cooperative housing resource group
Creators: name: Cull, Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: The United Housing Foundation (UHF) was founded in 1972 to provide organizational, administrative, and technical advice to housing cooperatives in British Columbia. The purpose of the Foundation was to promote the success of housing cooperatives through the centralization of the substantial knowledge and skills hitherto scattered throughout many small groups in the cooperative sector. Within three and one-half years UHF grew from a grassroots organization under the auspices of the credit union movement to a government funded bureaucracy capable of producing over 1000 cooperative units annually. UHF's apparent success was marred by a bitter conflict be-UHF and its client cooperatives who charged the organization with elitism, insensitivity, and failure to represent cooperatives and by a provincial review of the Foundation and subsequent withholding of funds. These events led to the final collapse of UHF in February 1976. This thesis investigates the role of UHF and concludes that it was a divisive force in the cooperative movement in this province. It was discovered that the local cooperative movement was severely damaged by UHF's frustration of individual cooperatives' needs, provincial interference in UHF policy, and UHF's less-than-professional technical services. The problems of UHF were found to pertain to a large extent to difficulties inherent in the dual nature of cooperative housing — both economic enterprise and . social movement — and the distinct lack of Cooperation among cooperatives. The main recommendations are for self-financing and, therefore, resource groups representative of the cooperatives served, and for the establishment of several types of resource groups to meet the various needs of different housing cooperatives, a recognition that the field is too diverse to be contained within one group. i

Application of Abel-Plana formula for collapse and revival of Rabi oscillations in Jaynes-Cummings model
Creators: name: Azuma, Hiroo
Publisher: name: arXiv
Year: 2009
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In this paper, we give an analytical treatment to study the behavior of the collapse and the revival of the Rabi oscillations in the Jaynes-Cummings model (JCM). The JCM is an exactly soluble quantum mechanical model, which describes the interaction between a two-level atom and a single cavity mode of the electromagnetic field. If we prepare the atom in the ground state and the cavity mode in a coherent state initially, the JCM causes the collapse and the revival of the Rabi oscillations many times in a complicated pattern in its time-evolution. In this phenomenon, the atomic population inversion is described with an intractable infinite series. (When the electromagnetic field is resonant with the atom, the $n$th term of this infinite series is given by a trigonometric function for $\sqrt{n}t$, where $t$ is a variable of the time.) According to Klimov and Chumakov's method, using the Abel-Plana formula, we rewrite this infinite series as a sum of two integrals. We examine the physical meanings of these two integrals and find that the first one represents the initial collapse (the semi-classical limit) and the second one represents the revival (the quantum correction) in the JCM. Furthermore, we evaluate the first and second-order perturbations for the time-evolution of the JCM with an initial thermal coherent state for the cavity mode at low temperature, and write down their correction terms as sums of integrals by making use of the Abel-Plana formula.

description: We measure the clustering of dark matter halos in a large set of collisionless cosmological simulations of the flat LCDM cosmology. Halos are identified using the spherical overdensity algorithm, which finds the mass around isolated peaks in the density field such that the mean density is Delta times the background. We calibrate fitting functions for the large scale bias that are adaptable to any value of Delta we examine. We find a ~6% scatter about our best fit bias relation. Our fitting functions couple to the halo mass functions of Tinker et. al. (2008) such that bias of all dark matter is normalized to unity. We demonstrate that the bias of massive, rare halos is higher than that predicted in the modified ellipsoidal collapse model of Sheth, Mo, & Tormen (2001), and approaches the predictions of the spherical collapse model for the rarest halos. Halo bias results based on friends-of-friends halos identified with linking length 0.2 are systematically lower than for halos with the canonical Delta=200 overdensity by ~10%. In contrast to our previous results on the mass function, we find that the universal bias function evolves very weakly with redshift, if at all. We use our numerical results, both for the mass function and the bias relation, to test the peak-background split model for halo bias. We find that the peak-background split achieves a reasonable agreement with the numerical results, but ~20% residuals remain, both at high and low masses.

description: We employ the Delphi semi-analytical model to study the impact of black hole growth on high-redshift galaxies, both in terms of the observed UV luminosity and of the star formation rate. To do this, firstly, we assess the contribution of AGN to the total galaxy UV luminosity as a function of stellar mass and redshift. We find that for $M_{UV} < -24$ mag and $z \approx 5 - 6$ the galaxies for which the black hole UV luminosity outshines the stellar UV emission become the majority, and we estimate their duty cycle. Secondly, we study the evolution of the AGN and stellar luminosity functions (LFs), finding that it is driven both by changes in their characteristic luminosities (i.e. evolution of the intrinsic brightness of galaxies) and in their normalizations (i.e. evolution of the number densities of galaxies), depending on the luminosity range considered. Finally, we follow the mass assembly history for three different halo mass bins, finding that the magnitude of AGN-driven outflows depends on the host halo mass. We show that AGN feedback is most effective when the energy emitted by the accreting black hole is approximately $1\%$ of the halo binding energy, and that this condition is met in galaxies in halos with $M_h \sim 10^{11.75} M_\odot$ at $z=4$. In such cases, AGN feedback can drive outflows that are up to 100 times more energetic than SN-driven outflows, and the star formation rate is a factor of three lower than for galaxies of the same mass without black hole activity.

description: We consider the asymmetric branes model of modified gravity, which can produce late time acceleration of the universe and compare the cosmology of this model to the standard $Λ$CDM model and to the DGP braneworld model. We show how the asymmetric cosmology at relevant physical scales can be regarded as a one-parameter extension of the DGP model, and investigate the effect of this additional parameter on the expansion history of the universe.

description: The structure of the electrical double layer (EDL) formed near graphene in aqueous environments strongly impacts its performance for a plethora of applications, including capacitive deionization. In particular, adsorption and organization of multivalent counterions near the graphene interface can promote nonclassical behaviors of EDL including overcharging followed by co-ion adsorption. In this paper, we characterize the EDL formed near an electrified graphene interface in dilute aqueous $YCl_3$ solution using in situ high resolution x-ray reflectivity (also known as crystal truncation rod (CTR)) and resonant anomalous x-ray reflectivity (RAXR). These interfacial-specific techniques reveal the electron density profiles with molecular-scale resolution. We find that yttrium ions ($Y^{3+}$) readily adsorb to the negatively charged graphene surface to form an extended ion profile. This ion distribution resembles a classical diffuse layer but with a significantly high ion coverage, i.e., 1 $Y^{3+}$ per 11.4 $\pm$ 1.6 A$^2$, compared to the value calculated from the capacitance measured by cyclic voltammetry (1 $Y^{3+}$ per ~240 A$^2$). Such overcharging can be explained by co-adsorption of chloride that effectively screens the excess positive charge. The adsorbed $Y^{3+}$ profile also shows a molecular-scale gap ($\geq$5 A) from the top graphene surfaces, which is attributed to the presence of intervening water molecules between the adsorbents and adsorbates as well as the lack of inner-sphere surface complexation on chemically inert graphene. We also demonstrate controlled adsorption by varying the applied potential and reveal consistent $Y^{3+}$ ion position with respect to the surface and increasing cation coverage with decreasing applied potential.
Control of Spin Blockade by AC Magnetic Fields in Triple Quantum Dots

description: We analyze coherent spin phenomena in triple quantum dots in triangular configuration under crossed DC and AC magnetic fields. In particular, we discuss the interplay between Aharonov-Bohm current oscillations, coherent electron trapping and spin blockade under electron spin resonance conditions. We demonstrate that, for certain field frequencies, AC magnetic fields induce an antiresonant behavior in the current, allowing for both removal and restoration of entangled spin blockaded states by tuning the AC field frequency. Our theoretical predictions indicate how to manipulate spin qubits in a triangular quantum dot array.

description: For over 100 years, scientists have investigated the properties of the proton, which is one of the most abundant components of visible matter in the universe. Nevertheless, researchers do not fully understand many details about its internal structure and dynamics. Time-like electromagnetic form factors are one of the observable quantities that can help us achieve a deeper understanding. In this review article, we present an overview of the current experimental status in this field, consisting of measurements of the time-like reactions $e^{+}e^{-}\to p\bar{p}$, $p\bar{p}\to e^{+}e^{-}$, and future measurements of $p\bar{p}\to μ^{+}μ^{-}$. A focus is put on recent high precision results of the reaction $e^{+}e^{-}\to p\bar{p}$ that have been obtained after analyzing 688.5~pb$^{-1}$ of data taken at the BESIII experiment. They are compared and put into perspective to results from previous measurements in this channel. We discuss the channels $p\bar{p}\to e^{+}e^{-}$ and $p\bar{p}\toμ^{+}μ^{-}$ in terms of the few existing as well as future measurements, which the PANDA experiment will perform. Finally, we review several new theoretical models and phenomenological approaches inspired by the BESIII high precision results and then discuss their implications for a deeper understanding of the proton's structure and inner dynamics.

description: The first results from observations of the high mass X-ray binary LS 5039 using the Fermi Gamma-ray Space Telescope data between 2008 August and 2009 June are presented. Our results indicate variability that is consistent with the binary period, with the emission being modulated with a period of 3.903 +/- 0.005 days; the first detection of this modulation at GeV energies. The light curve is characterized by a broad peak around superior conjunction in agreement with inverse Compton scattering models. The spectrum is represented by a power law with an exponential cutoff, yielding an overall flux (100 MeV - 300 GeV) of 4.9 +/- 0.5(stat) +/- 1.8(syst) x 10^-7 photon cm^-2 s^-1, with a cutoff at 2.1 +/- 0.3(stat) +/- 1.1(syst) GeV and photon index Gamma = 1.9 +/- 0.1(stat) +/- 0.3(syst). The spectrum is observed to vary with orbital phase, specifically between inferior and superior conjunction. We suggest that the presence of a cutoff in the spectrum may be indicative of magnetospheric emission similar to the emission seen in many pulsars by Fermi.

The autonomy of modern sport: dangerous and endangered

description: From the point of view of sociological theories of societal differentiation, modern sport is one of about a dozen differentiated sub-systems of modern society. This analytical perspective raises the question of the systemic autonomy of modern sport. This question shall be dealt with by distinguishing further the two differentiated second-order sub-systems of sport: top athletics and leisure sport. Whereas for top athletics a dangerous autonomy – in the final end, dangerous to itself - can be diagnosed, leisure sport is characterized by an endangered autonomy. Interestingly, coping with these two very different problems of sub-systemic autonomy relies on a mutually legitimating double interchange among top athletics and popular sports. Thus, both sub-systems of modern sport cannot exist without and separated from each other.
Implementation of a single femtosecond optical frequency comb for rovibrational cooling

description: We show that a single femtosecond optical frequency comb may be used to induce two-photon transitions between molecular vibrational levels to form ultracold molecules, e.g., KRb. The phase across an individual pulse in the pulse train is sinusoidally modulated with a carefully chosen modulation amplitude and frequency. Piecewise adiabatic population transfer is fulfilled to the final state by each pulse in the applied pulse train providing a controlled population accumulation in the final state. Detuning the pulse train carrier and modulation frequency from one-photon resonances changes the time scale of molecular dynamics but leads to the same complete population transfer to the ultracold state. A standard optical frequency comb with no modulation is shown to induce similar dynamics leading to rovibrational cooling.
