    • Calculation of transition state energies in the hcn–hnc isomerization with an algebraic model. 

      Khalouf-Rivera, Jamil; Carvajal, Miguel; Pérez-Bernal, Francisco; Santos, Lea F. (American Chemical Society, 2019-10-09)
      Recent works have shown that the spectroscopic access to highly excited states provides enough information to characterize transition states in isomerization reactions. Here, we show that information about the transition ...
    • Caputo standard α-family of maps: Fractional difference vs. fractional 

      Edelman, Mark (Chaos: An Interdisciplinary Journal of Nonlinear Science, 2014-06)
      In this paper, the author compares behaviors of systems which can be described by fractional differential and fractional difference equations using the fractional and fractional difference Caputo standard α-Families of ...
    • Celebrating Pesach in the Land of the Pharaohs.

      Chalik, Lisa; Rivera, Cyrielle; Rhodes, Marjorie (American Psychological Association, 2014-10)
      Integrating generic information about categories with knowledge of specific individuals is a critical component of successful inductive inferences. The present study tested whether children’s approach to this task ...
    • The cognitive processes underlying moral judgment across development. 

      Chalik, Lisa; Rhodes, Marjorie; Van Bavel, Jay J. (Cognitive Science Society (CSS), 2018)
      Some moral philosophers have suggested that a basic prohibition against intentional harm ought to be at the core of moral belief systems across human societies. Yet, experimental work suggests ...

      Mondaini, Rubem; Krishnanand, Mallayya; Santos, Lea F.; Rigol, Marcos (American Physical Society, 2018-07-17)
    • The communication of naïve theories of the social world in parent–child conversation. 

      Chalik, Lisa; Rhodes, Marjorie (Taylor & Francis, 2015-07-13)
      Three studies examined the communication of naïve theories of social groups in conversations between parents and their 4-year-old children (N=48). Parent-child dyads read and discussed a storybook in which they either ...
    • Decay of a thermofield-double state in chaotic quantum systems. 

      del Campo, A.; Molina-Vilaplana, J.; Santos, Lea F.; Sonner, J. (EDP Sciences, 2018-09)
      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 ...
    • Dynamical Detection of Level Repulsion in the One-Particle Aubry-André Model. 

      Torres-Herrera, E. Jonathan; Santos, Lea F. (MDPI : Multidisciplinary Digital Publishing Institute, 2020-01-20)
      Abstract: The analysis of level statistics provides a primary method to detect signatures of chaos in the quantum domain. However, for experiments with ion traps and cold atoms, the energy levels are not as easily ...
    • Dynamical signatures of quantum chaos and relaxation time scales in a spin-boson system. 

      Santos, Lea F.; Bastarrachea-Magnani, M. A.; Lerma-Hernández, S.; Torres-Herrera, E.J.; Hirsch, J.G.; Villaseñor, D. (American Physical Society, 2019-07-31)
      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 ...

      Lerma-Hernández, S.; Villaseñor, D.; Bastarrachea-Magnani, M. A.; Torres-Herrera, E.J.; Santos, Lea F.; Hirsch, J.G. (Philip Allan Publishers Limited, 2019-05-10)
      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 many-body localization transition. 

      Torres-Herrera, E.J.; Santos, Lea F. (American Physical Society, 2015-07)
      The isolated one-dimensional Heisenberg model with static random magnetic fields has become paradigmatic for the analysis of many-body localization. Here, we study the dynamics of this system initially prepared in a ...
    • The early Bronze Age fortifications at Tell Es-Safi/Gath, Israel. 

      Katz, Jill; Shai, Itzhaq; Chadwick, Jeffrey R.; Welch, Eric; Greenfield, Haskey J.; Maeir, Aren M. (Routledge: Taylor & Francis Group, 2016)
      Tell es-Safi/Gath is a multi-period 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. 

      Santos, Lea F. (American Physical Society, 2003-06)
      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 ...

      Santos, Lea F.; Rigol, Marcos; Polkovnikov, Anatoli (American Physical Society, 2011-07-18)
      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 out-of-equilibrium ...
    • Excited-state quantum phase transitions studied from a non-Hermitian perspective. 

      Sindelka, Milan; Santos, Lea F.; Moiseyev, Nimrod (American Physical Society, 2017-01-24)
      A main distinguishing feature of non-Hermitian 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 ...
