Unified Light-Matter Floquet Theory and its Application to Quantum Communication
Georg Engelhardt, Sayan Choudhury, W. Vincent Liu
Periodically-driven quantum systems can exhibit a plethora of intriguing non-equilibrium phenomena that can be analyzed using Floquet theory. Naturally, Floquet theory is employed…
Quasi-Discrete Time Crystals in the quasiperiodically driven Lipkin-Meshkov-Glick model
Sk Anisur, W. Vincent Liu, Sayan Choudhury
A discrete time crystal (DTC) is a remarkable non-equilibrium phase of matter characterized by the persistent sub-harmonic oscillations of physical observables in periodically driv…
Route to Extend the Lifetime of a Discrete Time Crystal in a Finite Spin Chain Without Disorder
Sayan Choudhury
Periodically driven (Floquet) systems are described by time dependent Hamiltonians that possess discrete time translation symmetry. The spontaneous breaking of this symmetry leads…
Long-range-ordered phase in a quantum Heisenberg chain with interactions beyond nearest neighbors
Zehan Li, Sayan Choudhury, W. Vincent Liu
Spin ensembles coupled to optical cavities provide a powerful platform for engineering synthetic quantum matter. Recently, we demonstrated that cavity mediated infinite range inter…
Localized dynamics following a quantum quench in a non-integrable system: An example on the sawtooth ladder
Rishabh Khare, Sayan Choudhury
Motivated by the recent discovery of ergodicity breaking in geometrically frustrated systems, we study the quench dynamics of interacting hardcore bosons on a sawtooth ladder. We i…
Fast scrambling without appealing to holographic duality
Zehan Li, Sayan Choudhury, W. Vincent Liu
Motivated by the question of whether all fast scramblers are holographically dual to quantum gravity, we study the dynamics of a non-integrable spin chain model composed of two ing…
