Van Hove singularities in the paramagnetic phase of the Hubbard model: a DMFT study
Rok Zitko, Janez Bonca, Thomas Pruschke
Using the dynamical mean-field theory (DMFT) we study the paramagnetic phase of the Hubbard model with the density of states (DOS) corresponding to the three-dimensional cubic latt…
A new collective phenomenon arising from spin anisotropic perturbations to a Heisenberg square lattice manifested in paramagnetic resonance experiments
S. Cox, R. D. McDonald, J. Singleton +6
We report unexpected behaviour in a family of Cu spin- 1/2 systems, in which an apparent gap in the low energy magneto-optical absorption spectrum opens at low temperature. This pr…
Bipolaron in the t-J model coupled to longitudinal and transverse quantum lattice vibrations
Lev Vidmar, Janez Bonca, Sadamichi Maekawa +1
We explore the influence of two different polarizations of quantum oxygen vibrations on the spacial symmetry of the bound magnetic bipolaron in the context of the t-J model by usin…
