Random matrix approach in search for weak signals immersed in background noise
Random matrix weak signals immerse background noise

Abstract: We present new, original and alternative method for searching signals coded in noisy data. The method is based on the properties of random matrix eigenvalue spectra. First, we describe gener...
A general and solvable random matrix model for spin decoherence
general and solvable random matrix model spin decoherence
2010/10/21
We propose and solve a simple but very general quantum model of an SU(2)spin interacting with a large external system with N states. The coupling is described by a random hamiltonian in a new general ...
