Quantum and classical lyapunov exponents in atomfield interaction systems
(American Physical Society, 20190115)The exponential growth of the outoftimeordered correlator (OTOC) has been proposed as a quantum signature of classical chaos. The growth rate is expected to coincide with the classical Lyapunov exponent. This quantumclassical ... 
Quantum and Classical Lyapunov Exponents in AtomField Interaction Systems.
(arXiv.org, 20180726)The exponential growth of the outoftimeordered correlator (OTOC) has been proposed as a quantum sig nature of classical chaos. The growth rate is expected to coincide with the classical Lyapunov exponent. ... 
Quantum chaos and thermalization in gapped systems.
(American Physical Society, 201007)We investigate the onset of thermalization and quantum chaos in finite onedimensional gapped systems of hardcore bosons. Integrability in these systems is broken by nextnearestneighbor repulsive interactions, which ... 
Quantum Chaos and Thermalization in Isolated Systems of Interacting Particles.
(American Physical Society, 2016)This review is devoted to the problem of thermalization in a small isolated conglomerate of interacting constituents. A variety of physically important systems of intensive current interest belong to this category: complex ... 
Quantum vs classical dynamics in a spinboson system: manifestations of spectral correlations and scarring.
(IOP Publishing ; Deutsche Physikalische Gesellschaft, 20200430)We compare the entire classical and quantum evolutions of the Dicke model in its regular and chaotic domains. This is a paradigmatic interacting spinboson model of great experimental interest. By studying the classical ... 
Realistic ManyBody Quantum Systems vs. Full Random Matrices: Static and Dynamical Properties.
(MDPI, 2016)We study the static and dynamical properties of isolated manybody quantum systems and compare them with the results for full random matrices. In doing so, we link concepts from quantum information theory with those from ... 
The relationship between the Jewish people and Yerushalayim: A historical account of the first 400 years.
(Yeshiva University. Th, 2013) 
Relaxation, chaos, and thermalization in a threemode model of a Bose–Einstein condensate.
(IOP Publishing, 20181127)We study the complex quantum dynamics of a system of many interacting atoms in an elongated an harmonic trap. The system is initially in a Bose–Einstein condensed state, well described by Thomas–Fermi profile in the ... 
Religious persecution, civil war, and bureaucratic mischief: A Chanukah story fo the ages.
(Yeshiva University, 2015)The vagaries of the Jewish experience are all manifest in the story of Chanukah. Some, such as religious persecution and factional tensions, are so familiar that we are almost inured to them. Others may make us pause as ... 
Selfaveraging behavior at the metalinsulator transition of manybody quantum systems out of equilibrium .
(201910)An observable of a disordered system is selfaveraging when its properties do not depend on the specific realization considered. Lack of selfaveraging, on the other hand, implies that sample to sample fluctuations persist ... 
Selfaveraging in manybody quantum systems out of equilibrium.
(arXiv.org, 20190627)Despite its importance to experiments, numerical simulations, and the development of theoretical models, selfaveraging in manybody quantum systems out of equilibrium remains underinvestigated. Usually, in the chaotic ... 
Selfaveraging in manybody quantum systems out of equilibrium: Approach to the localized phase.
(American Physical Society, 20200923)The selfaveraging behavior of interacting manybody quantum systems has been mostly studied at equilibrium. The present paper addresses what happens out of equilibrium, as the increase of the strength of onsite disorder ... 
Selfaveraging in manybody quantum systems out of equilibrium: Chaotic systems.
(American Physical Society, 20200526)Despite its importance to experiments, numerical simulations, and the development of theoretical models,selfaveraging in manybody quantum systems out of equilibrium remains under investigated. Usually, in the chaotic ... 
Selfaveraging in manybody quantum systems out of equilibrium: Time dependence of distributions.
(American Chemical Society, 20200528)In a disordered system, a quantity is selfaveraging when the ratio between its variance over disorder realizations and the square of its mean decreases as the system size increases. Here, we consider a chaotic disordered ... 
Sensitivity of quantum information to environment perturbations measured with a nonlocal outoftimeorder correlation function.
(American Physical Society, 20200224)In a quantum system coupled with a nonMarkovian environment, quantum information may flow out of or into the system. Measuring quantum information flow and its sensitivity to perturbations is important for a better ... 
Sensitivity of quantum information to environment perturbations measured with the outoftimeorder correlation function.
(arXiv.org, 20180813)Measures to quantify the flow of quantum information and its sensitivity to environment perturbations are needed to better understand the evolution of open quantum systems and to distinguish nonMarkovian from Markovian ... 
Signatures of chaos and thermalization in the dynamics of manybody quantum systems.
(arXiv.org, 20180417)We extend the results of two of our papers [Phys. Rev. A 94, 041603R (2016) and Phys. Rev. B 97, 060303R (2018)] that touch upon the intimately connected topics of quantum chaos and thermalization. In the first, we argued ... 
Signatures of chaos and thermalization in the dynamics of manybody quantum systems.
(Springer Berlin Heidelberg, 201903)We extend the results of two of our papers [Phys. Rev. A 94, 041603R (2016) and Phys. Rev. B 97, 060303R (2018)] that touch upon the intimately connected topics of quantum chaos and thermalization. In the first, we argued ... 
Social categories as markers of intrinsic interpersonal obligations.
(SAGE Publications, 201306)Social categorization is an earlydeveloping feature of human social cognition, yet the role that social categories play in how children understand and predict human behavior has been unclear. These studies test whether ... 
Speck of chaos.
(American Physical Society, 2020)It has been shown that, despite being local, a perturbation applied to a single site of the onedimensional XXZ model is enough to bring this interacting integrable spin1/2 system to the chaotic regime. Here, we show ...
