On stability of fixed points and chaos in fractional systems.
(Chaos, 2018)In this paper, we propose a method to calculate asymptotically period two sinks and define the range of stability of fixed points for a variety of discrete fractional systems of the order 0<α<2 . The method is tested on ... -
On the fractional Eulerian numbers and equivalence of maps with long term power-law memory (integral Volterra equations of the second kind) to Grünvald-Letnikov fractional difference (differential) equations
(Chaos: An Interdisciplinary Journal of Nonlinear Science, 2015)In this paper, we consider a simple general form of a deterministic system with power-law memory whose state can be described by one variable and evolution by a generating function. A new value of the system's variable is ... -
Onset of quantum chaos in one-dimensional bosonic and fermionic systems and its relation to thermalization.
(American Physical Society, 2010)By means of full exact diagonalization, we study level statistics and the structure of the eigenvectors of one-dimensional gapless bosonic and fermionic systems across the transition from integrability to quantum chaos. ... -
Plagues 4 to 6: Wild animals, pestilence, and boils
(Stern College for Women, Yeshiva University, 2011)The Ibn Ezra (Shemos 9:1) noted that the plagues of blood and frogs were mediated through the medium of water, of lice and wild animals through the medium of soil, and of pestilence and boils through the medium of the ... -
Plagues 7 to 10
(Stern College for Women, Torah Activities Council (TAC), Yeshiva University, 2012)Hail, Lightning, and Thunder: The 7th Plague “HaShem said to Moshe, Stretch out your hand toward the sky and there will be hail throughout all Egypt. It will fall on man and animal and on all outdoor plants all over ... -
Positive quantum Lyapunov exponents in classically regular systems.
(arXiv.org, 2019-09-09)Quantum chaos refers to signatures of classical chaos found in the quantum domain. Recently, it has become common to equate the exponential behavior of the quantum evolution of out-of-time order correlators (OTOCs) with ... -
Positive quantum Lyapunov exponents in experimental systems with a regular classical limit.
(American Physical Society, 2020-01-22)Quantum chaos refers to signatures of classical chaos found in the quantum domain. Recently, it has become common to equate the exponential behavior of out-of-time order correlators (OTOCs) with quantum chaos. The ... -
Preschoolers use social allegiances to predict behavior.

Probing the edge between integrability and quantum chaos in interacting few-atom systems.
(arXiv preprint, 2021-04-27)Interacting quantum systems in the chaotic domain are at the core of various ongoing studies of many-body physics, ranging from the scrambling of quantum information to the onset of thermalization. We propose a minimum ... -
Quantum and classical lyapunov exponents in atom-field interaction systems
(American Physical Society, 2019-01-15)The exponential growth of the out-of-time-ordered 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 quantum-classical ... -
Quantum and Classical Lyapunov Exponents in Atom-Field Interaction Systems.
(arXiv.org, 2018-07-26)The exponential growth of the out-of-time-ordered 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, 2010-07)We investigate the onset of thermalization and quantum chaos in finite one-dimensional gapped systems of hard-core bosons. Integrability in these systems is broken by next-nearest-neighbor 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 spin-boson system: manifestations of spectral correlations and scarring.
(IOP Publishing ; Deutsche Physikalische Gesellschaft, 2020-04-30)We compare the entire classical and quantum evolutions of the Dicke model in its regular and chaotic domains. This is a paradigmatic interacting spin-boson model of great experimental interest. By studying the classical ... -
Quantum-classical correspondence of a system of interacting bosons in a triple-well potential.
(2021-05-21)We study the quantum-classical correspondence of an experimentally accessible system of interacting bosons in a tilted triple-well potential. With the semiclassical analysis, we get a better understanding of the different ... -
The quick drive to pseudo-equilibrium.
(Nature Physics, 2021-01-04)- A clever application of nuclear magnetic resonance techniques offers a glimpse at a quantum system driven at high frequency, resulting in Floquet prethermalization — a quasi-steady state that persists for a very long time. -
Realistic Many-Body Quantum Systems vs. Full Random Matrices: Static and Dynamical Properties.
(MDPI, 2016)We study the static and dynamical properties of isolated many-body 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.

Relaxation, chaos, and thermalization in a three-mode model of a Bose–Einstein condensate.
(IOP Publishing, 2018-11-27)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 ...
