Magnetic transitions induced by pressure and magnetic field in a two-orbital -electron model in cubic and tetragonal lattices
A. C. Lausmann, E. J. Calegari, Julián Faúndez +2
We investigate the onset and evolution of under the simultaneous application of pressure and magnetic field of distinct itinerant Néel states using the underscreened Anderson Latti…
Unfolding of antiferromagnetic phases and multicritical points in a two-orbital model for Uranium compounds under pressure and magnetic field
S. G. Magalhaes, A. C. Lausmann, E. J. Calegari +1
We investigate the occurrence of multicritical points under pressure and magnetic field in a model that describes two 5f bands (of either or characters) which hybridize wit…
Pseudogap and the specific heat of high T superconductors: a Hubbard model in a n-pole approximation
E. J. Calegari, A. C. Lausmann, S. G. Magalhaes +2
In this work the specific heat of a two-dimensional Hubbard model, suitable to discuss high- superconductors (HTSC), is studied taking into account hopping to first () and…
Interplay between condensation energy, pseudogap and the specific heat of a Hubbard model in a n-pole approximation
A. C. Lausmann, E. J. Calegari, S. G. Magalhaes +2
The condensation energy and the specific heat jump of a two-dimensional Hubbard model, suitable to discuss high- superconductors, is studied. In this work, the Hubbard model i…
