Electronic Mechanism for the Coexistence of Ferroelectricity and Ferromagnetism
C. D. Batista, J. E. Gubernatis, Wei-Guo Yin
We study the strong coupling limit of a two-band Hubbard Hamiltonian that also includes an inter-orbital on-site repulsive interaction . When the two bands have opposite pa…
Gamma5 quasiparticles and avoided quantum criticality in U(Ru,Rh)2Si2
N. Harrison, A. V. Silhanek, C. D. Batista +4
We discuss recent specific heat data in high magnetic fields on URu2Si2 and 4% Rh-doped URu2Si2 as well as previously published de Haas-van Alphen data at lower magnetic fields in…
Phase diagram of the one-dimensional, two-channel Kondo lattice model
T. Schauerte, D. L. Cox, R. M. Noack +2
Employing the density matrix renormalization group method and strong-coupling perturbation theory, we study the phase diagram of the SU(2)xSU(2) Kondo lattice model in one dimensio…
Hierarchical Mean-Field Theories
Gerardo Ortiz, Cristian D. Batista
We present a systematic and reliable methodology, termed hierarchical mean-field theory (HMFT), to study and predict the behavior of strongly coupled many-particle systems. HMFT is…
Stripes, topological order, and deconfinement in a planar t-Jz model
J. Smakov, C. D. Batista, G. Ortiz
We determine the quantum phase diagram of a two-dimensional bosonic t-Jz model as a function of the lattice anisotropy gamma, using a quantum Monte Carlo loop algorithm. We show an…
Spin-Particle Connections
C. D. Batista, G. Ortiz
This is a topical review on the generalization of the Jordan-Wigner transformations to any spin and spatial dimensions.
