Gaussian resolutions for equilibrium density matrices
P. Frantsuzov, A. Neumaier, V. A. Mandelshtam
A Gaussian resolution method for the computation of equilibrium density matrices rho(T) for a general multidimensional quantum problem is presented. The variational principle appli…

Explicit effective Hamiltonians for general linear quantum-optical networks
U. Leonhardt, A. Neumaier
Linear optical networks are devices that turn classical incident modes by a linear transformation into outgoing ones. In general, the quantum version of such transformations may mi…

Ensembles and experiments in classical and quantum physics
Arnold Neumaier
A philosophically consistent axiomatic approach to classical and quantum mechanics is given. The approach realizes a strong formal implementation of Bohr's correspondence principle…
