Locally conformally Kähler structures on unimodular Lie groups
(Springer, 2015-12)
We study left-invariant locally conformally Kähler structures on Lie groups, or equivalently, on Lie algebras. We give some properties of these structures in general, and then we consider the special cases when its complex ...
Haldane phase in one-dimensional topological Kondo insulators
(American Physical Society, 2015-11)
We investigate the ground-state properties of a recently proposed model for a topological Kondo insulator in one dimension (i.e., the p-wave Kondo-Heisenberg lattice model) by means of the density-matrix renormalization-group ...
Transição de fase quântica e modelos de spins frustrados
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2007-03-15)
In this thesis, we will study the quantum phase transition of frustrated quantum spin
models: (i) van Hemmen model ( S = 1) with transverse and anisotropic biaxial field (ii)
Heisenberg model (S = 1/2 ) with competitive ...
Continuous phase-space methods on discrete phase spaces
(EPL Association, 2015)
We show that discrete quasiprobability distributions defined via the discrete
Heisenberg-Weyl group can be obtained as discretizations of the continuous SU(N) quasiprobability
distributions. This is done by identifying ...
