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…
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…
Collective modes of ultracold fermionic alkaline-earth gases with SU(N) symmetry
Sayan Choudhury, Kazi R. Islam, Yanhua Hou +3
We calculate the collective modes of ultracold trapped alkaline-earth fermionic atoms, which possess an SU() symmetry of the nuclear spin degree of freedom, and a controllable $…
Dynamics of Bose-Einstein Recondensation in Higher Bands
Vaibhav Sharma, Sayan Choudhury, Erich J. Mueller
Motivated by recent experiments, we explore the kinetics of Bose-Einstein condensation in the upper band of a double well optical lattice. These experiments engineer a non-equilibr…
Emergent periodic and quasiperiodic lattices on surfaces of synthetic Hall tori and synthetic Hall cylinders
Yangqian Yan, Shao-Liang Zhang, Sayan Choudhury +1
Synthetic spaces allow physicists to bypass constraints imposed by certain physical laws in experiments. Here, we show that a synthetic torus, which consists of a ring trap in the…
Bose-Einstein Condensate on a Synthetic Topological Hall Cylinder
Chuan-Hsun Li, Yangqian Yan, Shih-Wen Feng +4
The interplay between matter particles and gauge fields in physical spaces with nontrivial geometries can lead to novel topological quantum matter. However, detailed microscopic me…
