Hamiltonian description of nonreciprocal interactions
Yu-Bo Shi, Roderich Moessner, Ricard Alert +1
In a vast class of systems, which includes members as diverse as sedimenting particles and bird flocks, interactions do not stem from a potential, and are in general nonreciprocal.…
Prethermalization in periodically-driven nonreciprocal many-body spin systems
Adam J. McRoberts, Hongzheng Zhao, Roderich Moessner +1
We analyze a new class of time-periodic nonreciprocal dynamics in interacting chaotic classical spin systems, whose equations of motion are conservative (phase-space-volume-preserv…
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…
Thermalization and Prethermalization in Periodically Kicked Quantum Spin Chains
Christoph Fleckenstein, Marin Bukov
We study the dynamics of periodically-kicked many-body systems away from the high-frequency regime, and discuss a family of Floquet systems where the notion of prethermalization ca…
Prethermalization and Thermalization in Periodically-Driven Many-Body Systems away from the High-Frequency Limit
Christoph Fleckenstein, Marin Bukov
We investigate a class of periodically driven many-body systems that allows us to extend the phenomenon of prethermalization to the vicinity of isolated intermediate-to-low drive f…
Asymptotic Prethermalization in Periodically Driven Classical Spin Chains
Owen Howell, Phillip Weinberg, Dries Sels +2
We reveal a continuous dynamical heating transition between a prethermal and an infinite-temperature stage in a clean, chaotic periodically driven classical spin chain. The transit…
Broken symmetry in a two-qubit quantum control landscape
Marin Bukov, Alexandre G. R. Day, Phillip Weinberg +3
We analyze the physics of optimal protocols to prepare a target state with high fidelity in a symmetrically coupled two-qubit system. By varying the protocol duration, we find a di…
