Tunable Mpemba Effect in a Prethermal Many-Body Spin Network
Chaitali Shah, Cooper M. Selco, Leo Joon Il Moon +1
Relaxation in an interacting system is determined not only by its initial distance from equilibrium, but also by the relaxation modes populated by the initial state. Here we experi…
A geometric framework for spin relaxation
Sophia N. Fricke, Kieren A. Harkins, Ashok Ajoy +1
Spin relaxation is conventionally described by two independent phenomenological rates - longitudinal () and transverse () - whose separation obscures a deeper structural…
Breakdown of Disorder-Suppressed Floquet Heating under Two-Frequency Driving
Cooper M. Selco, Christian Bengs, Chaitali Shah +1
Periodic (Floquet) driving enables Hamiltonian engineering and nonequilibrium phases, but interacting systems eventually heat by absorbing energy from the drive. Disorder can great…
Robust Quantum Sensing via Prethermal Spin Orbits
Enrico Daniel Richter, Ryan J. Smith, Brayden Glockzin +3
Practical performance of quantum sensors is often curtailed by uncontrolled environmental drift (bias-field instability, temperature fluctuations, mechanical vibration), background…
