Magnetization plateaux in the classical Shastry-Sutherland lattice

M. Moliner, D. C. Cabra, A. Honecker +2

We investigated the classical Shastry-Sutherland lattice under an external magnetic field in order to understand the recently discovered magnetization plateaux in the rare-earth te…

Generalized Pomeranchuk instabilities in graphene

C. A. Lamas, D. C. Cabra, N. Grandi

We study the presence of Pomeranchuk instabilities induced by interactions on a Fermi liquid description of a graphene layer. Using a recently developed generalization of Pomeranch…

Magnetization Process of the Classical Heisenberg Model on the Shastry-Sutherland Lattice

M. Moliner, D. C. Cabra, A. Honecker +2

We investigate classical Heisenberg spins on the Shastry-Sutherland lattice and under an external magnetic field. A detailed study is carried out both analytically and numerically…

Fermi Liquid instabilities in two-dimensional lattice models

C. A. Lamas, D. C. Cabra, N. Grandi

We develop a procedure for detecting Fermi liquid instabilities by extending the analysis of Pomeranchuk to two-dimensional lattice systems. The method is very general and straight…

Incidence of the boundary shape in the effective theory of fractional quantum Hall edges

D. C. Cabra, N. E. Grandi

Starting from a microscopic description of a system of strongly interacting electrons in a strong magnetic field in a finite geometry, we construct the boundary low energy effectiv…

Generalized rotational hamiltonians from nonlinear angular momentum algebras

A. Ballesteros, O. Civitarese, F. J. Herranz +1

Higgs algebras are used to construct rotational Hamiltonians. The correspondence between the spectrum of a triaxial rotor and the spectrum of a cubic Higgs algebra is demonstrated.…
