Probing Entanglement in Adiabatic Quantum Optimization with Trapped Ions
Philipp Hauke, Lars Bonnes, Markus Heyl +1
Adiabatic quantum optimization has been proposed as a route to solve NP-complete problems, with a possible quantum speedup compared to classical algorithms. However, the precise ro…
Many-body localization and quantum ergodicity in disordered long-range Ising models
Philipp Hauke, Markus Heyl
Ergodicity in quantum many-body systems is - despite its fundamental importance - still an open problem. Many-body localization provides a general framework for quantum ergodicity,…
Dynamical quantum phase transitions in systems with broken-symmetry phases
Markus Heyl
In this work it is shown that dynamical quantum phase transitions in Loschmidt echos control the nonequilibrium dynamics of the order parameter after particular quantum quenches in…
Dynamics of symmetry breaking during quantum real-time evolution in a minimal model system
Markus Heyl, Matthias Vojta
One necessary criterion for the thermalization of a nonequilibrium quantum many-particle system is ergodicity. It is, however, not sufficient in case where the asymptotic long-time…
