Damping and Pseudo-fermions [PDF]
Fabio BagarelloAfter a short abstract introduction on the time evolution driven by non self-adjoint hamiltonians, we show how the recently introduced concept of {\em pseudo-fermion} can be used in the description of damping in finite dimensional quantum systems, and we compare the results deduced adopting the Schr\"odinger and the Heisenberg representations.View original: http://arxiv.org/abs/1212.3663
