Enhancement in Breaking of Time-reversal Invariance in the Quantum Kicked Rotor
Ramgopal Agrawal, Akhilesh Pandey, Sanjay Puri
We study the breaking of time-reversal invariance (TRI) by the application of a magnetic field in the quantum kicked rotor (QKR), using Izrailev's finite-dimensional model. There i…
Quantum Chaotic Systems and Random Matrix Theory
Akhilesh Pandey, Avanish Kumar, Sanjay Puri
This article is an introductory review of random matrix theory (RMT) and its applications, with special focus on quantum chaos. Random matrices were first used by Wigner to underst…
Finite-Range Coulomb Gas Models II: Applications to Quantum Kicked Rotors and Banded Random Matrices
Avanish Kumar, Akhilesh Pandey, Sanjay Puri
In paper I of this two-stage exposition, we introduced finite-range Coulomb gas (FRCG) models, and developed an integral-equation framework for their study. We obtained exact analy…
Finite-Range Coulomb Gas Models I: Some Analytical Results
Akhilesh Pandey, Avanish Kumar, Sanjay Puri
Dyson has shown an equivalence between infinite-range Coulomb gas models and classical random matrix ensembles for the study of eigenvalue statistics. In this paper, we introduce f…
Universality classes of quantum chaotic dissipative systems
Ambuja Bhushan Jaiswal, Ravi Prakash, Akhilesh Pandey
We study the ensemble of complex symmetric matrices. The ensemble is useful in the study of effect of dissipation on systems with time reversal invariance. We consider the nearest…
Finite-Range Coulomb Gas Models of Banded Random Matrices and Quantum Kicked Rotors
Akhilesh Pandey, Avanish Kumar, Sanjay Puri
Dyson demonstrated an equivalence between infinite-range Coulomb gas models and classical random matrix ensembles for study of eigenvalue statistics. We introduce finite-range Coul…
