    Complexity of Jackiw-Teitelboim gravity 
    Brown, Adam R.; Gharibyan, Hrant; Lin, Henry W.; Susskind, Leonard; Thorlacius, Larus; Zhao, Ying (American Physical Society (APS), 2019-02-25)
    The Jackiw-Teitelboim (JT) model arises from the dimensional reduction of charged black holes. Motivated by the holographic complexity conjecture, we calculate the late-time rate of change of action of a Wheeler-DeWitt patch in the JT theory. ...

    Falling toward charged black holes 
    Brown, Adam R.; Gharibyan, Hrant; Streicher, Alexandre; Susskind, Leonard; Thorlacius, Larus; Zhao, Ying (American Physical Society (APS), 2018-12-28)
    The growth of the “size” of operators is an important diagnostic of quantum chaos. Susskind conjectured that the holographic dual of the size is proportional to the average radial component of the momentum of the particle created by the operator. Thus ...

    Generalized global symmetries in states with dynamical defects: The case of the transverse sound in field theory and holography 
    Grozdanov, Sašo; Poovuttikul, Napat (American Physical Society (APS), 2018-05-11)
    In this work, we show how states with conserved numbers of dynamical defects (strings, domain walls, etc.) can be understood as possessing generalized global symmetries even when the microscopic origins of these symmetries are unknown. Using this ...

    Holography and hydrodynamics with weakly broken symmetries 
    Grozdanov, Sašo; Lucas, Andrew; Poovuttikul, Napat (American Physical Society (APS), 2019-04-15)
    Hydrodynamics is a theory of long-range excitations controlled by equations of motion that encode the conservation of a set of currents (energy, momentum, charge, etc.) associated with explicitly realized global symmetries. If a system possesses ...

    Observational constraints on secret neutrino interactions from big bang nucleosynthesis 
    Huang, Guo-yuan; Ohlsson, Tommy; Zhou, Shun (American Physical Society (APS), 2018-04-05)
    We investigate possible interactions between neutrinos and massive scalar bosons via g ϕ ¯ ν ν ϕ (or massive vector bosons via g V ¯ ν γ μ ν V μ ) and explore the allowed parameter space of the coupling constant g ϕ (or g V ) ...
