Fluctuation-stable generalized entropy probes of spectral heterogeneity
Arpita Goswami
Generalized entropy measures are widely used to characterize localization and multifractality, and the regime \(q>1\) is often empirically found to exhibit improved numerical stabi…
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…
Information Theoretic Signatures of Localization and Mobility Edges in Quasiperiodic Systems
Arpita Goswami
We investigate localization transitions and mobility edge phenomena in one-dimensional quasiperiodic lattice models using an information theoretic framework based on the Tsallis en…
Nonextensive Thermodynamics of the Morse Oscillator: Signature and Solid State Application
Arpita Goswami
In this work, we present a detailed thermodynamic analysis of a bound quantum system: the Morse oscillator within the framework of Tsallis nonextensive statistics. Using the proper…
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…
Exact mobility edges in a slowly varying quasiperiodic ladder model
Arpita Goswami
We propose a minimal two-leg ladder model in which the mobility edge (ME) arises solely due to bond modulation, introduced through a slowly varying quasiperiodic modulation in the…
