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…
Continuous-Time Random Walk Description of Anomalous Spin Transport in Dilute Dipolar Networks
Cooper M. Selco, Christian Bengs, Ashok Ajoy
Nuclear spin diffusion is often summarized by a single diffusion coefficient, but this coarse-grained description can fail in dilute solids where positional disorder and long-range…
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…
Emergent Decoherence Dynamics in Doubly Disordered Spin Networks
Cooper M. Selco, Christian Bengs, Chaitali Shah +2
Elucidating the emergence of irreversible macroscopic laws from reversible quantum many-body dynamics is a question of broad importance across all quantum science. Many-body decohe…
Cryogenic field-cycling instrument for optical NMR hyperpolarization studies
Noella D'Souza, Kieren A. Harkins, Cooper Selco +10
Optical dynamic nuclear polarization (DNP) offers an attractive approach to enhancing the sensitivity of nuclear magnetic resonance (NMR) spectroscopy. Efficient, optically-generat…
