Metamagnetic transition in the two orbitals Kondo lattice model
Christopher Thomas, Sébastien Burdin, Claudine Lacroix
In this work, we study the effects of a transverse magnetic field in a Kondo lattice model with two orbitals interacting with the conduction electrons. The electrons that a…
Incommensurate charge density wave on multiband intermetallic systems exhibiting competing orders
Nei Lopes, Daniel Reyes, Natanael C. Costa +2
The appearance of an incommensurate charge density wave vector on multiband intermetallic systems presenting commensurate charge density wave (CDW) and sup…
Interplay between charge density wave and superconductivity in multi-band systems with inter-band Coulomb interaction
Nei Lopes, Daniel Reyes, Mucio A. Continentino +1
In this work we study the competition or coexistence between charge density wave (CDW) and superconductivity (SC) in a two-band model system in a square lattice. One of the bands h…
Influence of the symmetry of the hybridization on the critical temperature of multi-band superconductors
Daniel Reyes, Nei Lopes, Mucio A. Continentino +1
In this work we study a two-band model of a superconductor in a square lattice. One band is narrow in energy and includes local Coulomb correlations between its quasi-particles. Pa…
Spin liquid versus long range magnetic order in the frustrated body-centered tetragonal lattice
Carlene Farias, Christopher Thomas, Catherine Pépin +3
An -symmetric generalization of the Heisenberg model for quantum spin operators is used to investigate the geometrically frustrated body-centered tetragonal (BCT)…
s- and d-wave superconductivity in a two-band model
Daniel Reyes, Mucio A. Continentino, Christopher Thomas +1
Superconductivity in strongly correlated systems is a remarkable phenomenon that attracts a huge interest. The study of this problem is relevant for materials as the high Tc oxides…
Spin liquid versus long range magnetic order in the frustrated body-centered tetragonal lattice
Sébastien Burdin, Christopher Thomas, Catherine Pépin +2
The quantum Heisenberg model is studied in the geometrically frustrated body-centered tetragonal lattice(BCT lattice) with antiferromagnetic interlayer coupling J1 and intralayer f…
Effect of anisotropy in the underscreened Kondo lattice
Christopher Thomas, Acirete S. da Rosa Simões, Claudine Lacroix +2
We study the effect of crystal field anisotropy in the underscreened Kondo lattice model. Starting from the two orbital Anderson lattice model and including a local anisotrop…
3D Modulated Spin Liquid model applied to URuSi
Christopher Thomas, Sébastien Burdin, Catherine Pépin +1
We have developed a 3D version for the Modulated Spin Liquid in a body-centered tetragonal lattice structure to describe the hidden order observed in URuSi at $T_0\approx17…
Application of the S=1 underscreened Anderson lattice model to Kondo uranium and neptunium compounds
Christopher Thomas, Acirete S. da Rosa Simões, J. R. Iglesias +3
Magnetic properties of uranium and neptunium compounds showing the coexistence of Kondo screening effect and ferromagnetic order are investigated within the Anderson lattice Hamilt…
