The corresponding Lindblad equation has a time-periodic Liouvillian. The dynamics of …

Quantum chaos in a Bose-Hubbard dimer with modulated tunneling

RA Kidd, MK Olsen, JF Corney - Physical Review A, 2019 - APS
In the large-N, classical limit, the Bose-Hubbard dimer undergoes a transition to chaos when
its tunneling rate is modulated in time. We use exact and approximate numerical simulations …

Tuning quantum measurements to control chaos

JK Eastman, JJ Hope, ARR Carvalho - Scientific reports, 2017 - nature.com
Environment-induced decoherence has long been recognised as being of crucial
importance in the study of chaos in quantum systems. In particular, the exact form and …

Multiparameter estimation along quantum trajectories with sequential Monte Carlo methods

JF Ralph, S Maskell, K Jacobs - Physical Review A, 2017 - APS

Spatiotemporal spread of perturbations in a driven dissipative Duffing chain: An out-of-time-ordered correlator approach

AK Chatterjee, A Kundu, M Kulkarni - Physical Review E, 2020 - APS
Out-of-time-ordered correlators (OTOCs) have been extensively used as a major tool for
exploring quantum chaos, and recently there has been a classical analog. Studies have …

Chaos in continuously monitored quantum systems: An optimal-path approach

P Lewalle, J Steinmetz, AN Jordan - Physical Review A, 2018 - APS
We predict that continuously monitored quantum dynamics can be chaotic. The optimal
paths between past and future boundary conditions can diverge exponentially in time when …

Quantum Lyapunov exponents beyond continuous measurements
