Noncollinear twisted RKKY interaction on the optically driven SnTe(001) surface
Mohsen Yarmohammadi, Marin Bukov, Michael H. Kolodrubetz
The nontrivial spin texture on the (001) surface of topological crystalline insulator SnTe hosts exotic scientific importance and spintronic applications. Here, we study the effect…
Engineering and probing non-Abelian chiral spin liquids using periodically driven ultracold atoms
Bo-Ye Sun, Nathan Goldman, Monika Aidelsburger +1
We propose a scheme to implement Kitaev's honeycomb model with cold atoms, based on a periodic (Floquet) drive, in view of realizing and probing non-Abelian chiral spin liquids usi…
Making Trotterization adaptive and energy-self-correcting for NISQ devices and beyond
Hongzheng Zhao, Marin Bukov, Markus Heyl +1
Simulation of continuous time evolution requires time discretization on both classical and quantum computers. A finer time step improves simulation precision, but it inevitably lea…
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…
Continuously tracked, stable, large excursion trajectories of dipolar coupled nuclear spins
Ozgur Sahin, Hawraa Al Asadi, Paul Schindler +9
We report an experimental approach to excite, stabilize, and continuously track Bloch sphere orbits of dipolar-coupled nuclear spins in a solid. We demonstrate these results on a m…
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…
Self-Correcting Quantum Many-Body Control using Reinforcement Learning with Tensor Networks
Friederike Metz, Marin Bukov
Quantum many-body control is a central milestone en route to harnessing quantum technologies. However, the exponential growth of the Hilbert space dimension with the number of qubi…
Observation of a critical prethermal discrete time crystal created by two-frequency driving
William Beatrez, Christoph Fleckenstein, Arjun Pillai +8
We report the observation of long-lived Floquet prethermal discrete time crystalline (PDTC) order in a three-dimensional position-disordered lattice of interacting dipolar-coupled…
