An exact local mapping from clock-spins to fermions
Simone Traverso, Christoph Fleckenstein, Maura Sassetti +1
Clock-spin models are attracting great interest, due to both their rich phase diagram and their connection to parafermions. In this context, we derive an exact local mapping from c…
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…
Non-Hermitian topology in monitored quantum circuits
Christoph Fleckenstein, Alberto Zorzato, Daniel Varjas +3
We demonstrate that genuinely non-Hermitian topological phases and corresponding topological phase transitions can be naturally realized in monitored quantum circuits, exemplified…
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…
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…
