Homogenization of a nonlinear monotone problem in a locally periodic domain via unfolding method
S. Aiyappan, G. Cardone, C. Perugia +1
In this paper, the asymptotic behavior of the solutions of a monotone problem posed in a locally periodic oscillating domain is studied. Nonlinear monotone boundary conditions are…
Monotonicity Principle in Tomography of Nonlinear Conducting Materials
Antonio Corbo Esposito, Luisa Faella, Gianpaolo Piscitelli +2
We treat an inverse electrical conductivity problem which deals with the reconstruction of nonlinear electrical conductivity starting from boundary measurements in steady currents…
Out-of-time-order correlators in bipartite nonintegrable systems
Ravi Prakash, Arul Lakshminarayan
Out-of-time-order correlators (OTOC) being explored as a measure of quantum chaos, is studied here in a coupled bipartite system. Each of the subsystems can be chaotic or regular a…
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…
Scrambling in strongly chaotic weakly coupled bipartite systems: Universality beyond the Ehrenfest time-scale
Ravi Prakash, Arul Lakshminarayan
Out-of-time-order correlators (OTOC), vigorously being explored as a measure of quantum chaos and information scrambling, is studied here in the natural and simplest multi-particle…
Saturation of number variance in embedded random matrix ensembles
Ravi Prakash, Akhilesh Pandey
We study fluctuation properties of embedded random matrix ensembles of non-interacting particles. For ensemble of two non-interacting particle systems, we find that unlike the spec…
Universal spectral correlations in ensembles of random normal matrices
Ravi Prakash, Akhilesh Pandey
We consider non-gaussian ensembles of random normal matrices with the constraint that the ensembles are invariant under unitary transformations. We show that the level density of e…
