Anomalous suppression of quantum chaos between two integrable limits
Roopayan Ghosh, Henry Davenport, Frank Schindler
Level statistics in non-integrable quantum many-body systems with time reversal symmetry are expected to follow the Gaussian Orthogonal Ensemble (GOE), a hallmark of quantum chaos.…
Boundary Chaos: Exact Entanglement Dynamics
Felix Fritzsch, Roopayan Ghosh, Tomaž Prosen
We compute the dynamics of entanglement in the minimal setup producing ergodic and mixing quantum many-body dynamics, which we previously dubbed {\em boundary chaos}. This consists…
Mobility edge and multifractality in a periodically driven Aubry-André model
Madhumita Sarkar, Roopayan Ghosh, Arnab Sen +1
We study the localization-delocalization transition of Floquet eigenstates in a driven fermionic chain with an incommensurate Aubry-André potential and a hopping amplitude which is…
