Author(s): Francesco Coghi, Amarjit Budhiraja, and Juan P. GarrahanWe address the general problem of formulating the dynamical large deviations of non-Markovian systems in a closed form. Specifically, we consider a broad class of “self-interacting” jump processes whose dynamics depends on the past through a functional of a state-dependent empirical observable. Expl…[Phys. Rev.

Author(s): Raphael Holzinger, Nico S. Bassler, Julian Lyne, Susanne F. Yelin, and Claudiu GenesWe solve Dicke superradiance with two or more competing collective decay channels of tunable rates using a symbolic quantum-trajectory construction. The method yields closed time-domain populations and observables as finite combinations of exponential terms for arbitrary numbers of emitters and arbi…[Phys. Rev. […]

Author(s): Siddhartha Sarkar, Yitong Zhang, and Kai SunThe excitation spectrum of fractional Chern insulators is identical to their fractional quantum Hall counterparts except for an enhancement factor, making it possible to predict their excitation spectrum from the Landau-level problem.[Phys.

Author(s): Spenser Talkington, Benjamin Kass, and Martin ClaassenThe ultrastrong coupling regime of cavity photons and quantum materials has emerged as a pathway to modify materials properties. However, definitive signatures of ultrastrong coupling remain elusive. Focusing on the quantum photon statistics of light transmitted through a cavity-embedded superconduc…[Phys. Rev. Lett. 137, 196902] Published Fri Nov 06, […]

Author(s): Ewan McCulloch, Romain Vasseur, and Sarang GopalakrishnanIn charge neutral fluids, such as the Dirac fluid in graphene at the Dirac point, charge transport remains diffusive despite the presence of ballistically propagating sound waves: sound waves “hydrodynamically decouple” from the slower charge fluctuations. For quasi-one-dimensional charge neutral fl…[Phys. Rev. Lett. 137, 196304] Published Fri Nov […]
