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…
Anomalously extended Floquet prethermal lifetimes and applications to long-time quantum sensing
Kieren A. Harkins, Cooper Selco, Christian Bengs +8
Floquet prethermalization is observed in periodically driven quantum many-body systems where the system avoids heating and maintains a stable, non-equilibrium state, for extended p…
