Quantum thermalization in a dimerized J1-J2 model
Smitarani Mishra, Shaon Sahoo
We revisit the J1-J2 frustrated Heisenberg spin-1/2 chain with dimerization (δ) or modulation in the nearest-neighbor couplings to investigate its thermalization behavior. While th…

Quantum thermalization and average entropy of a subsystem
Smitarani Mishra, Shaon Sahoo
Page's seminal result on the average von Neumann (VN) entropy does not immediately apply to realistic many-body systems which are restricted to physically relevant smaller subspace…

Subsystem localization in a two-leg ladder system
Arpita Goswami, Pallabi Chatterjee, Ranjan Modak +1
We consider a ladder system where one leg, referred to as the ``bath", is governed by an Aubry-André (AA) type Hamiltonian, while the other leg, termed the ``subsystem", follows a…
