Dynamical semigroups in the Birkhoff polytope of order 3 as a tool for analysis of quantum channels
Mateusz Snamina, Emil J. Zak
In the present paper we show a link between bistochastic quantum channels and classical maps. The primary goal of this work is to analyse the multiplicative structure of the Birkho…
Magnon dressing by orbital excitations in ferromagnetic planes of KCuF and LaMnO
Mateusz Snamina, Andrzej M. Oleś
We show that even when spins and orbitals disentangle in the ground state, spin excitations are renormalized by the local tuning of orbitals in ferromagnetic planes of KC…
Spin-orbital model of stoichiometric LaMnO with tetragonal distortions
Mateusz Snamina, Andrzej M. Oleś
The model developed for LaMnO addresses the spin-orbital order by superexchange and Jahn-Teller orbital interactions in the cubic (perovskite) symmetry up to now whereas real c…
Spin-orbital order in undoped manganite LaMnO3 at finite temperature
Mateusz Snamina, Andrzej M. Oleś
We investigate the evolution of spin and orbital order in undoped LaMnO under increasing temperature with a model including both superexchange and Jahn-Teller interactions. We…
