Local measures of dynamical quantum phase transitions
Jad C. Halimeh, Daniele Trapin, Maarten Van Damme +1
In recent years, dynamical quantum phase transitions (DQPTs) have emerged as a useful theoretical concept to characterize nonequilibrium states of quantum matter. DQPTs are marked…
Discrete truncated Wigner approach to dynamical phase transitions in Ising models after a quantum quench
Reyhaneh Khasseh, Angelo Russomanno, Markus Schmitt +2
By means of the discrete truncated Wigner approximation we study dynamical phase transitions arising in the steady state of transverse-field Ising models after a quantum quench. St…
Geometrical quench and dynamical quantum phase transition in the lattice
Balázs Gulácsi, Markus Heyl, Balázs Dóra
We investigate quantum quenches and the Loschmidt echo in the two dimensional, three band model, a close descendant of the dice lattice. By adding a chemical potential to t…
Homogeneous Floquet time crystal protected by gauge invariance
Angelo Russomanno, Simone Notarnicola, Federica Maria Surace +3
We show that homogeneous lattice gauge theories can realize nonequilibrium quantum phases with long-range spatiotemporal order protected by gauge invariance instead of disorder. We…
Dynamical quantum phase transitions in collapse and revival oscillations of a quenched superfluid
Mateusz Lacki, Markus Heyl
In this work we revisit collapse and revival oscillations in superfluids suddenly quenched by strong local interactions for the case of a one-dimensional Bose-Hubbard model. As the…
Measuring the single-particle density matrix for fermions and hard-core bosons in an optical lattice
Luis A. Peña Ardila, Markus Heyl, André Eckardt
Ultracold atoms in optical lattices provide clean, tunable, and well-isolated realizations of paradigmatic quantum lattice models. With the recent advent of quantum-gas microscopes…
Dynamical Topological Quantum Phase Transitions for Mixed States
M. Heyl, J. C. Budich
We introduce and study dynamical probes of band structure topology in the post-quench time-evolution from mixed initial states of quantum many-body systems. Our construction genera…
Dynamical Quantum Phase Transitions in Spin Chains with Long-Range Interactions: Merging different concepts of non-equilibrium criticality
Bojan Zunkovic, Markus Heyl, Michael Knap +1
We theoretically study the dynamics of a transverse-field Ising chain with power-law decaying interactions characterized by an exponent , which can be experimentally realized in…
Observation of a dynamical topological phase transition
Nick Fläschner, Dominik Vogel, Matthias Tarnowski +7
Phase transitions are a fundamental concept in science describing diverse phenomena ranging from, e.g., the freezing of water to Bose-Einstein condensation. While the concept is we…
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…
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…
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…
