Competing chiral and multipolar electric phases in the extended Falicov-Kimball model
B. Zenker, H. Fehske, C. D. Batista
We study the effects of interband hybridization within the framework of an extended Falicov-Kimball model with itinerant and electrons. An explicit interband hybridization…
Stability of spontaneous quantum Hall state in the Triangular Kondo-lattice model
Yasuyuki Kato, Ivar Martin, C. D. Batista
We study the behavior of the quarter-filled Kondo lattice model on a triangular lattice by combining a zero-temperature variational approach and finite-temperature Monte-Carlo simu…
Effective Low-Energy Model for f-Electron Delocalization
K. A. Al-Hassanieh, Yi-feng Yang, Ivar Martin +1
We consider a Periodic Anderson Model (PAM) with a momentum-dependent inter-band hybridization that is strongly suppressed near the Fermi level. Under these conditions, we reduce t…
Vortex Viscosity in Magnetic Superconductors Due to Radiation of Spin Waves
A. Shekhter, L. N. Bulaevskii, C. D. Batista
In type-II superconductors that contain a lattice of magnetic moments, vortices polarize the magnetic system inducing additional contributions to the vortex mass, vortex viscosity,…
Finite-Temperature Transition in the Spin-Dimer Antiferromagnet BaCuSi2O6
Yoshitomo Kamiya, Naoki Kawashima, Cristian D. Batista
We consider a classical XY-like Hamiltonian on a body-centered tetragonal lattice, focusing on the role of interlayer frustration. A three-dimensional (3D) ordered phase is realize…
Superconductivity in strongly repulsive fermions: the role of kinetic-energy frustration
L. Isaev, G. Ortiz, C. D. Batista
We discuss a physical mechanism of a non-BCS nature which can stabilize a superconducting state in a {\it strongly repulsive} electronic system. By considering the two-dimensional…
