Bias and Correlations in Quasiperiodicity: Impact on Localization in an Extended Aubry-André Model
Adithya J D, Ranjan Modak, Shaon Sahoo
Unlike in Anderson localization - where any amount of uncorrelated disorder localizes all eigenstates in one dimension - a one-dimensional system with quasiperiodic potential suppo…
Entangling Power Dynamics: Ergodicity and Mixing
Rahul V, Ranjan Modak, Shaon Sahoo +1
We study quantum dynamics through the lens of entanglement generation and characterize the underlying unitary evolution by the distinct signatures it imprints on the time-dependent…
Anderson localization via Peierls phase modulation
Arpita Goswami, Pallabi Chatterjee, Ranjan Modak +1
We investigate a two leg ladder system subjected to an external magnetic field. In the absence of a magnetic field, the system is described by a clean tight binding model, with no…
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…
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…
Phase transitions in -state clock model
Arpita Goswami, Ravi Kumar, Monikana Gope +1
The state clock model, sometimes called the discrete model, is known to show a second-order (symmetry breaking) phase transition in two-dimension (2D) for (…
