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…

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…

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…
