Dissipative Stabilization of Floquet-Engineered Many-Body Order
Shreyas Raman, Robin Schäfer, Alicia J. Kollar +1
Floquet driving underlies Hamiltonian and gate engineering, and produces dynamical orders with no equilibrium counterpart. These phenomena are, however, transient in well-isolated…
Realization of a Quantum Topological Photon Pump
Qianao Yue, Bernardo Barrera, Martin Ritter +4
Topological pumps transfer charge or energy at quantized rates determined solely by band topology, independent of the details of the control fields. Photon pumps operating on this…
Probing Hilbert space fragmentation using controlled dephasing
Dominik Vuina, Robin Schäfer, David M. Long +1
Dynamical constraints in many-body quantum systems can lead to Hilbert space fragmentation, wherein the system's evolution is restricted to small subspaces of Hilbert space called…
Predicting Dynamics from Flows of the Eigenstate Thermalization Hypothesis
Dominik Hahn, David M. Long, Marin Bukov +1
Analytical treatments of far-from-equilibrium quantum dynamics are few, even in well-thermalizing systems. The celebrated eigenstate thermalization hypothesis (ETH) provides a post…
The Moving Born-Oppenheimer Approximation
Bernardo Barrera, Daniel P. Arovas, Anushya Chandran +1
We develop a mixed quantum-classical framework, dubbed the Moving Born-Oppenheimer Approximation (MBOA), to describe the dynamics of slow degrees of freedom (DOFs) coupled to fast…
A strong-driving toolkit for topological Floquet energy pumps with superconducting circuits
Martin Ritter, David M. Long, Qianao Yue +3
Topological Floquet energy pumps -- which use periodic driving to create a topologically protected quantized energy current -- have been proposed and studied theoretically, but hav…
