Quantum Noise and Self-Sustained Radiation of -Symmetric Systems

H Schomerus - Physical review letters, 2010 - APS
The observation that PT-symmetric Hamiltonians can have real-valued energy levels even if
they are non-Hermitian has triggered intense activities, with experiments, in particular …

Systematic approach to statistics of conductance and shot-noise in chaotic cavities

Sinc-based method for an efficient solution in the direct space of quantum wave equations with periodic boundary conditions

P Marconcini, D Logoteta, M Macucci - Journal of Applied Physics, 2013 - pubs.aip.org
The solution of differential problems, and in particular of quantum wave equations, can in
general be performed both in the direct and in the reciprocal space. However, to achieve the …

Enhanced wave transmission in random media with mirror symmetry
