Decay of a thermofielddouble state in chaotic quantum systems.
(EDP Sciences, 201809)Scrambling in interacting quantum systems out of equilibrium is particularly effective in the chaotic regime. Under time evolution, initially localized information is said to be scrambled as it spreads throughout the entire ... 
The dependence of Rabbi David Kimhi (Radak) on Rashi in his quotation of midrashic traditions.
(University of Pennsylvania Press, 200304)This article demonstrates that the 13thcentury exegete Rabbi David Kimhi (Radak) relied on Rashi as a source for midrashic traditions, in addition to his known use of Rashi as a resource for exegetical interpretations. ... 
Dynamical signatures of quantum chaos and relaxation timescales in a spinboson system.
(Philip Allan Publishers Limited, 20190510)Quantum systems whose classical counterparts are chaotic typically have highly correlated eigenvalues and level statistics that coincide with those from ensembles of full random matrices. A dynamical manifestation of these ... 
Dynamics at the manybody localization transition.
(American Physical Society, 201507)The isolated onedimensional Heisenberg model with static random magnetic fields has become paradigmatic for the analysis of manybody localization. Here, we study the dynamics of this system initially prepared in a ... 
The early Bronze Age fortifications at Tell EsSafi/Gath, Israel.
(Routledge: Taylor & Francis Group, 2016)Tell esSafi/Gath is a multiperiod site located on the border between the Judean foothills (Shephelah) and the southern coastal plain in central Israel, which has been subject to survey and excavations over the last two ... 
Entanglement in quantum computers described by the XXZ model with defects.
(American Physical Society, 200306)We investigate on how to generate maximally entangled states in systems characterized by the Hamiltonian of the XXZ model with defects. Some proposed quantum computers are described by such a model. Defects embedded in ... 
Entropy of Isolated Quantum Systems after a Quench.
(American Physical Society, 20110718)A diagonal entropy, which depends only on the diagonal elements of the system’s density matrix in the energy representation, has been recently introduced as the proper definition of thermodynamic entropy in outofequilibrium ... 
Excitedstate quantum phase transitions studied from a nonHermitian perspective.
(American Physical Society, 20170124)A main distinguishing feature of nonHermitian quantum mechanics is the presence of exceptional points (EPs). They correspond to the coalescence of two energy levels and their respective eigenvectors. Here, we use the ... 
Exponentially fast dynamics in the Fock space of chaotic man ybody systems.
(arXiv.org, 20180222)We demonstrate analytically and numerically that in isolated quantum systems of many interacting particles, the number of states participating in the evolution after a quench increases exponentially in time, provided the ... 
From few to manybody quantum systems.
(IOP Publishing, 20180903)How many particles are necessary to make a quantum system manybody? To answer this question, we take as reference for the manybody limit a quantum system at halffilling and compare its properties with those of a system ... 
Generic dynamical features of quenched interacting quantum systems: Survival probability, density imbalance, and outoftimeordered correlator.
(American Physical Society, 20180223)We study numerically and analytically the quench dynamics of isolated manybody quantum systems. Using full random matrices from the Gaussian orthogonal ensemble, we obtain analytical expressions for the evolution of the ... 
Level Repulsion and Dynamics in the Finite OneDimensional Anderson Model.
(Philip Allan Publishers Limited, 20190912)This work shows that dynamical features typical of full random matrices can be observed also in the simple finite onedimensional (1D) noninteracting Anderson model with nearest neighbor couplings. In the thermodynamic ... 
Localization and the effects of symmetries in the thermalization properties of onedimensional quantum systems.
(American Physical Society, 2010)We study how the proximity to an integrable point or to localization as one approaches the atomic limit, as well as the mixing of symmetries in the chaotic domain, may affect the onset of thermalization in finite onedimensional ... 
A note on rabbinic titles and the communities that create them.
(The Michael Scharf Publication Trust of Yeshiva University Press ; Maggid Books, 2018) 
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 powerlaw memory (integral Volterra equations of the second kind) to GrünvaldLetnikov 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 powerlaw 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 onedimensional 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 onedimensional gapless bosonic and fermionic systems across the transition from integrability to quantum chaos. ... 
Positive quantum Lyapunov exponents in classically regular systems.
(arXiv.org, 20190909)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 outoftime order correlators (OTOCs) with ... 
Preschoolers use social allegiances to predict behavior.
(Taylor & Francis (Routledge), 2014) 
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. ...
