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…

Statistical entropy of quantum systems
Smitarani Mishra, Shaon Sahoo
Statistical formulations of thermodynamic entropy, such as those by Boltzmann and Gibbs, were originally developed for classical systems and are well understood in that context. Ho…

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 t…
