Site occupation constraints in mean-field approaches of quantum spin systems at finite temperature
Raoul Dillenschneider, Jean Richert
We study the effect of site occupation on the description of quantum spin systems at finite temperature and mean-field level. We impose each lattice site to be occupied by a single…
A Renormalisation Approach to Effective Interactions in Hilbert Space
J. Richert
The low-lying bound states of a microscopic quantum many-body system of particles and the related physical observables can be worked out in a truncated --particle Hilbert sp…
Modelling static impurities
Sebastiao Correia, Janos Polonyi, Jean Richert
A simple model is presented for the calculation of the quenched average over impurities which are rendered static by setting their mass equal to infinity. The path integral formali…
An effective theory for conductance by symmetry breaking
Sebastiao Correia, Janos Polonyi, Jean Richert
An effective theory is suggested for the particle-anti particle and the particle-particle modes of strongly disordered electron systems. The effective theory is studied in the fram…
Decay of hot, rotating, compound nuclei
K. Pomorski, K. Dietrich, W. Przystupa +2
The fusion process and the competition between fission and n, p and alpha-particle emission is studied. The calculations are performed for nuclei at excitation energies from 80 MeV…
