Absence of disordered Thouless pumps at finite frequency
Dominik Vuina, David M. Long, Philip J. D. Crowley +1
A Thouless pump is a slowly driven one-dimensional band insulator which pumps charge at a quantised rate. Previous work showed that pumping persists in weakly disordered chains, an…
Prethermal stability of eigenstates under high frequency Floquet driving
Nicholas O'Dea, Fiona Burnell, Anushya Chandran +1
Systems subject to high-frequency driving exhibit Floquet prethermalization, that is, they heat exponentially slowly on a time scale that is large in the drive frequency, $τ_{\rm h…
Beyond Fermi's golden rule with the statistical Jacobi approximation
David M. Long, Dominik Hahn, Marin Bukov +1
Many problems in quantum dynamics can be cast as the decay of a single quantum state into a continuum. The time-dependent overlap with the initial state, called the fidelity, chara…
Unitary k-designs from random number-conserving quantum circuits
Sumner N. Hearth, Michael O. Flynn, Anushya Chandran +1
Local random circuits scramble efficiently and accordingly have a range of applications in quantum information and quantum dynamics. With a global charge however, the scramb…
Giant energy oscillations mediated by a quasiperiodically driven qubit
Dominik Vuina, David M. Long, Phillip J. D. Crowley +1
A qubit driven by two incommensurate frequencies can mediate a quantised average energy current in the adiabatic limit. We show that non-adiabatic processes result in reversals of…
Integrability and quench dynamics in the spin-1 central spin XX model
Long-Hin Tang, David M. Long, Anatoli Polkovnikov +2
Central spin models provide an idealized description of interactions between a central degree of freedom and a mesoscopic environment of surrounding spins. We show that the family…
