Parametric Number Covariance in Quantum Chaotic Spectra
Vinayak, Sandeep Kumar, Akhilesh Pandey
We study spectral parametric correlations in quantum chaotic systems and introduce the number covariance as a measure of such correlations. We derive analytic results for the class…

Subsystem dynamics under random Hamiltonian evolution
Vinayak, Marko Znidaric
We study time evolution of a subsystem's density matrix under unitary evolution, generated by a sufficiently complex, say quantum chaotic, Hamiltonian, modeled by a random matrix.…
