  • Dark matter searches at the LHC 

    Butler, John Mark (Sissa Medialab, 2018-07-31)
  • Geodesic paths for quantum many-body systems 

    Tomka, Michael; Souza, Tiago; Rosenberg, Steven; Polkovnikov, Anatoli (American Physical Society, 2016-06-19)
    We propose a method to obtain optimal protocols for adiabatic ground-state preparation near the adiabatic limit, extending earlier ideas from [D. A. Sivak and G. E. Crooks, Phys. Rev. Lett. 108, 190602 (2012)] to quantum ...
  • Natural stabilization of the Higgs boson’s mass and alignment 

    Lane, Kenneth; Shepherd, William
    Current data from the LHC indicate that the 125 GeV Higgs boson, H , is either the single Higgs of the Standard Model or, to a good approximation, an "aligned Higgs." We propose that H is the pseudo-Goldstone dilaton of ...
  • Magnetic field tuning of charge and spin order in the cuprate superconductors 

    Polkovnikov, Anatoli; Sachdev, S.; Vojta, M.; Demler, E. (WORLD SCIENTIFIC PUBL CO PTE LTD, 2002-08-30)
    Recent neutron scattering, nuclear magnetic resonance, and scanning tunneling microscopy experiments have yielded valuable new information on the interplay between charge and spin density wave order and superconductivity ...
  • Decay of superfluid currents in a moving system of strongly interacting bosons 

    Polkovnikov, Anatoli; Altman, E.; Demler, E.; Halperin, B.; Lukin, M. D. (AMER PHYSICAL SOC, 2005-06-01)
    We analyze the stability and decay of supercurrents of strongly interacting bosons on optical lattices. At the mean-field level, the system undergoes an irreversible dynamic phase transition, whereby the current decays ...
  • Nonequilibrium Gross-Pitaevskii dynamics of boson lattice models 

    Polkovnikov, Anatoli; Sachdev, Subir; Girvin, S. M. (AMERICAN PHYSICAL SOC, 2002-11-01)
    Motivated by recent experiments on trapped ultracold bosonic atoms in an optical lattice potential, we consider the nonequilibrium dynamic properties of such bosonic systems for a number of experimentally relevant situations. ...
  • Geometric speed limit of accessible many-body state preparation 

    Bukov, Marin; Sels, Dries; Polkovnikov, Anatoli (AMER PHYSICAL SOC, 2019-02-20)
    We analyze state preparation within a restricted space of local control parameters between adiabatically connected states of control Hamiltonians. We formulate a conjecture that the time integral of energy fluctuations ...
  • Dynamic trapping near a quantum critical point 

    Kolodrubetz, Michael; Katz, Emanuel; Polkovnikov, Anatoli (AMER PHYSICAL SOC, 2015-02-26)
    The study of dynamics in closed quantum systems has been revitalized by the emergence of experimental systems that are well-isolated from their environment. In this paper, we consider the closed-system dynamics of an ...
  • Cluster truncated Wigner approximation in strongly interacting systems 

    Wurtz, Jonathan; Polkovnikov, Anatoli; Sels, Dries (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2018-08-01)
    We present a general method by which linear quantum Hamiltonian dynamics with exponentially many degrees of freedom is replaced by approximate classical nonlinear dynamics with the number of degrees of freedom (phase space ...
  • Dynamical stability of a many-body Kapitza pendulum 

    Citro, Roberta; Dalla Torre, Emanuele G.; D'Alessio, Luca; Polkovnikov, Anatoli; Babadi, Mehrtash; Oka, Takashi; Demler, Eugene (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2015-09-01)
    We consider a many-body generalization of the Kapitza pendulum: the periodically-driven sine–Gordon model. We show that this interacting system is dynamically stable to periodic drives with finite frequency and amplitude. ...
