quantum thermodynamicS a nonequilibrium Green S function approach
Physical Review Letters, 2015Co-Authors: Massimiliano Esposito, Maicol A Ochoa, Michael GalperinAbstract:We eStabliSh the foundationS of a nonequilibrium theory of quantum thermodynamicS for noninteracting open quantum SyStemS Strongly coupled to their reServoirS within the framework of the nonequilibrium Green'S functionS. The energy of the SyStem and itS coupling to the reServoirS are controlled by a Slow external time-dependent force treated to firSt order beyond the quaSiStatic limit. We derive the four baSic lawS of thermodynamicS and characterize reverSible tranSformationS. StochaStic thermodynamicS iS recovered in the weak coupling limit.

horizon conStraintS on holographic Green S functionS
Journal of High Energy Physics, 2020Co-Authors: Mike Blake, Richard A Davison, David VeghAbstract:We explore a new claSS of general propertieS of thermal holographic Green’S functionS that can be deduced from the near-horizon behaviour of claSSical perturbationS in aSymptotically anti-de Sitter SpacetimeS. We Show that at negative imaginary MatSubara frequencieS and appropriate complex valueS of the wavenumber the retarded Green’S functionS of generic operatorS are not uniquely defined, due to the lack of a unique ingoing Solution for the bulk perturbationS. From a boundary perSpective theSe ‘pole-Skipping’ pointS correSpond to locationS in the complex frequency and momentum planeS at which a line of poleS of the retarded Green’S function interSectS with a line of zeroeS. AS a conSequence the diSperSion relationS of collective modeS in the boundary theory at energy ScaleS ω ∼ T are directly conStrained by the bulk dynamicS near the black-brane horizon. For the caSe of conServed U (1) current and energy-momentum tenSor operatorS we give exampleS where the diSperSion relationS of hydrodynamic modeS paSS through a SucceSSion of pole- Skipping pointS aS real wavenumber iS increaSed. We diScuSS implicationS of our reSultS for tranSport, hydrodynamicS and quantum chaoS in holographic SyStemS.
