Heating and many-body resonances in a periodically driven two-band system
Marin Bukov, Markus Heyl, David A. Huse +1
We study the dynamics and stability in a strongly interacting resonantly driven two-band model. Using exact numerical simulations, we find a stable regime at large driving frequenc…
Robustness of many-body localization in the presence of dissipation
Emanuele Levi, Markus Heyl, Igor Lesanovsky +1
Many-body localization (MBL) has emerged as a novel paradigm for robust ergodicity breaking in closed quantum many-body systems. However, it is not yet clear to which extent MBL su…
Prethermalization and Thermalization of a Quenched Interacting Luttinger Liquid
Michael Buchhold, Markus Heyl, Sebastian Diehl
We study the relaxation dynamics of interacting, one-dimensional fermions with band curvature after a weak quench in the interaction parameter. After the quench, the system is desc…
Measuring multipartite entanglement via dynamic susceptibilities
Philipp Hauke, Markus Heyl, Luca Tagliacozzo +1
Entanglement plays a central role in our understanding of quantum many body physics, and is fundamental in characterising quantum phases and quantum phase transitions. Developing p…
Many-body localization in a quantum simulator with programmable random disorder
Jacob Smith, Aaron Lee, Philip Richerme +6
When a system thermalizes it loses all local memory of its initial conditions. This is a general feature of open systems and is well described by equilibrium statistical mechanics.…
Stretched exponential decay of Majorana edge modes in many-body localized Kitaev chains under dissipation
Alexander Carmele, Markus Heyl, Christina Kraus +1
We investigate the resilience of symmetry-protected topological edge states at the boundaries of Kitaev chains in the presence of a bath which explicitly introduces symmetry-breaki…
Dynamical quantum phase transitions: scaling and universality
Markus Heyl
Dynamical quantum phase transitions (DQPTs) at critical times appear as non-analyticities during nonequilibrium quantum real-time evolution. Although there is evidence for a close…
Dynamical Topological Order Parameters far from Equilibrium
Jan Carl Budich, Markus Heyl
We introduce a topological quantum number -- coined dynamical topological order parameter (DTOP) -- that is dynamically defined in the real-time evolution of a quantum many-body sy…
