Optimal performance in a chaotic Floquet quantum battery
Lakshmija N K, Uma Divakaran
We study a quantum battery consisting of qubits interacting uniformly with each other. Starting from its ground state, the battery is charged by introducing periodic kicks in t…
Symmetry structure dependent diagnostic of the Quantum Mpemba Effect
Tamizhselvan S, Manju C, Bijay Kumar Agarwalla +1
Understanding symmetry restoration in isolated quantum many-body systems is an important problem in nonequilibrium many-body quantum physics. Recent studies have shown that the qua…
Floquet thermalization by power-law induced permutation symmetry breaking
Manju C, Uma Divakaran
Permutation symmetry plays a central role in the understanding of collective quantum dynamics. By introducing power law couplings that algebraically decay with the distance between…
Disordering a permutation symmetric system: revivals, thermalization and chaos
Manju C, Uma Divakaran, Arul Lakshminarayan
This study explores the effects of introducing a symmetry breaking disorder on the dynamics of a system invariant under particle permutation. The disorder forces quantum states, co…
Chaos controlled and disorder driven phase transitions induced by breaking permutation symmetry
Manju C, Arul Lakshminarayan, Uma Divakaran
The effects of disorder and chaos on quantum many-body systems can be superficially similar, yet their interplay has not been sufficiently explored. This work finds a continuous ph…
The promises and challenges of many-body quantum technologies: a focus on quantum engines
Victor Mukherjee, Uma Divakaran
Can many-body systems be beneficial to designing quantum technologies? We address this question by examining quantum engines, where recent studies indicate potential benefits throu…
