Quantum many-body Jarzynski equality and dissipative noise on a digital quantum computer
Dominik Hahn, Maxime Dupont, Markus Schmitt +2
The quantum Jarzynski equality and the Crooks relation are fundamental laws connecting equilibrium processes with nonequilibrium fluctuations. They are promising tools to benchmark…
Semiclassical echo dynamics in the Sachdev-Ye-Kitaev model
Markus Schmitt, Dries Sels, Stefan Kehrein +1
The existence of a quantum butterfly effect in the form of exponential sensitivity to small perturbations has been under debate for a long time. Lately, this question gained increa…
Irreversible dynamics in quantum many-body systems
Markus Schmitt, Stefan Kehrein
Irreversibility, despite being a necessary condition for thermalization, still lacks a sound understanding in the context of isolated quantum many-body systems. In this work we app…
Effective time reversal and echo dynamics in the transverse field Ising model
Markus Schmitt, Stefan Kehrein
The question of thermalisation in closed quantum many-body systems has received a lot of attention in the past few years. An intimately related question is whether a closed quantum…
Dynamical Quantum Phase Transitions in the Kitaev Honeycomb Model
Markus Schmitt, Stefan Kehrein
The notion of a dynamical quantum phase transition (DQPT) was recently introduced in [Heyl et al., Phys. Rev. Lett. 110, 135704 (2013)] as the non-analytic behavior of the Loschmid…
