Fixed Points, Floquet Entanglement Asymmetry, and Quantum Mpemba Effects
Jayashish Das, Filiberto Ares, Arnab Kundu
We investigate the dynamics of entanglement asymmetry in periodically driven two-dimensional conformal field theories with a global U symmetry, using a dynamical-system descri…
Quantum chaos and late-time equipartition of symmetry-resolved Krylov complexity
Jayashish Das, Suman Das, Juan F. Pedraza +1
We study symmetry-resolved Krylov complexity in finite-dimensional chaotic quantum many-body systems. When both the Hamiltonian and the initial operator commute with a conserved ch…
Floquet mobility edges and transport in a periodically driven generalized Aubry-André model
Jayashis Das, Vatsana Tiwari, Manish Kumar +1
We investigate the effect of a periodic electric field drive on the generalized Aubry-André model, also known as the Ganeshan-Pixley-Das Sarma (GPD) model, which is well known as a…
Symmetry Resolved Entanglement Entropy: Equipartition under Driven and Non-unitary Evolution in a Compact Boson CFT
Filiberto Ares, Jayashish Das, Arnab Kundu
We study the evolution of symmetry-resolved entanglement entropy in bulk-driven Floquet conformal field theories (CFTs). Focusing on the two-dimensional free compact boson CFT, we…
Flowery Horizons & Bulk Observers: Drive in Holographic CFT
Jayashish Das, Arnab Kundu
We explore and analyze bulk geometric aspects corresponding to a driven two-dimensional holographic CFT, where the drive Hamiltonian is constructed from the $sl^{(q)}(2,\mathbb{R})…
