On pseudo-stochastic matrices and pseudo-positive maps
D. Chruściński, V. I. Man'ko, G. Marmo +1
Stochastic matrices and positive maps in matrix algebras proved to be very important tools for analysing classical and quantum systems. In particular they represent a natural set o…
Two--mode optical tomograms: a possible experimental check of the Robertson uncertainty relations
V. I. Man'ko, G. Marmo, A. Simoni +1
The experimental check of two--mode Robertson uncertainty relations and inequalities for highest quadrature moments is suggested by using homodyne photon detection. The relation be…
On the effects of the magnetic field and the isotopic substitution upon the infrared absorption of manganites
C. A. Perroni, V. Cataudella, G. De Filippis +3
Employing a variational approach that takes into account electron-phonon and magnetic interactions in perovskites with , the effects of the magnetic fie…
Polaron and bipolaron formation in the Hubbard-Holstein model: role of next-nearest neighbor electron hopping
G. De Filippis, V. Cataudella, G. Iadonisi +3
The influence of next-nearest neighbor electron hopping, , on the polaron and bipolaron formation in a square Hubbard-Holstein model is investigated within a variationa…
