Efficient implementation of the Wang-Landau algorithm for systems with length-scalable potential energy functions
Santosh Kumar, Girish Kumar, Rohit S. Chandramouli +1
We consider a class of systems where identical particles with positions and momenta are enclosed in a box of size , and e…
Distributions of Off-Diagonal Scattering Matrix Elements: Exact Results
André Nock, Santosh Kumar, Hans-Jürgen Sommers +1
Scattering is a ubiquitous phenomenon which is observed in a variety of physical systems which span a wide range of length scales. The scattering matrix is the key quantity which p…
Distribution of Scattering Matrix Elements in Quantum Chaotic Scattering
Santosh Kumar, André Nock, Hans-Jürgen Sommers +5
Scattering is an important phenomenon which is observed in systems ranging from the micro- to macroscale. In the context of nuclear reaction theory the Heidelberg approach was prop…
Random matrix ensembles: Wang-Landau algorithm for spectral densities
Santosh Kumar
We propose a method based on the Wang-Landau algorithm to numerically generate the spectral densities of random matrix ensembles. The method employs Dyson's log-gas formalism for r…
Entanglement in random pure states: Spectral density and average von Neumann entropy
Santosh Kumar, Akhilesh Pandey
Quantum entanglement plays a crucial role in quantum information, quantum teleportation and quantum computation. The information about the entanglement content between subsystems o…
Jacobi Crossover Ensembles of Random Matrices and Statistics of Transmission Eigenvalues
Santosh Kumar, Akhilesh Pandey
We study the transition in conductance properties of chaotic mesoscopic cavities as time-reversal symmetry is broken. We consider the Brownian motion model for transmission eigenva…
