Floquet-engineered quantum state manipulation in a noisy qubit
Eric Boyers, Mohit Pandey, David K. Campbell +3
Adiabatic evolution is a common strategy for manipulating quantum states and has been employed in diverse fields such as quantum simulation, computation and annealing. However, adi…
Thermal radiation and dissipative phase transition in a BEC with local loss
Dries Sels, Eugene Demler
We study the dynamics of an atomic BEC subject to local dissipation in the form of atom losses. We show there is a critical loss rate at which the system undergoes a continuous dis…
Cluster Truncated Wigner Approximation in Strongly Interacting Systems
Jonathan Wurtz, Anatoli Polkovnikov, Dries Sels
We present a general method by which linear quantum Hamiltonian dynamics with exponentially many degrees of freedom is replaced by approximate classical nonlinear dynamics with the…
Geometric Speed Limit of Accessible Many-Body State Preparation
Marin Bukov, Dries Sels, Anatoli Polkovnikov
We analyze state preparation within a restricted space of local control parameters between adiabatically connected states of control Hamiltonians. We formulate a conjecture that th…
Glassy Phase of Optimal Quantum Control
Alexandre G. R. Day, Marin Bukov, Phillip Weinberg +2
We study the problem of preparing a quantum many-body system from an initial to a target state by optimizing the fidelity over the family of bang-bang protocols. We present compell…
Semiclassical echo dynamics in the Sachdev-Ye-Kitaev model
Markus Schmitt, Dries Sels, Stefan Kehrein +1
The existence of a quantum butterfly effect in the form of exponential sensitivity to small perturbations has been under debate for a long time. Lately, this question gained increa…
