Dimensional Compactification and Two-Particle Binding
(Wiley-Blackwell, 2011-06-01)
The renormalization group equations (RGE) are applied to the study of two-body singular interactions at the surface of an infinite long cylinder with a radius R. A single scale, independent of R, emerges from the renormalization ...
Combined (13)C NMR and DFT/GIAO studies of the polyketides Aurasperone A and Fonsecinone A
(Wiley-Blackwell, 2008-11-05)
Structural characterization by NMR spectroscopy and DFT calculations was performed for two dimeric naptho-gamma-pyrones, the polyketides Aurasperone A and Fonsecinone A. Experimental data ((13)C NMR chemical shifts and ...

Spin squeezing and entanglement via finite-dimensional discrete phase-space description
(2013-02-01)
We show how mapping techniques inherent to N2-dimensional discrete phase spaces can be used to treat a wide family of spin systems which exhibits squeezing and entanglement effects. This algebraic framework is then applied ...

On membrane interactions and a three-dimensional analog of Riemann surfaces
(2016-02-01)
Abstract: Membranes in M-theory are expected to interact via splitting and joining processes. We study these effects in the pp-wave matrix model, in which they are associated with transitions between states in sectors built ...
Flavour singlets in gauge theory as permutations
(2016-12-01)
Gauge-invariant operators can be specified by equivalence classes of permutations. We develop this idea concretely for the singlets of the flavour group SO(Nf) in U(Nc) gauge theory by using Gelfand pairs and Schur-Weyl ...
Modelo de Hubbard extendido para fermiones con tres grados de libertad internos
(Bogotá - Ciencias - Maestría en Ciencias - FísicaDepartamento de FísicaUniversidad Nacional de Colombia - Sede Bogotá, 2019-04-20)
En la presente tesis se considera fermiones con tres grados de libertad internos en una dimensión, sistema que puede ser descritos por un modelo de Fermi-Hubbard SU(3), al cual se adiciona un término de interacción a ...
Theoretical study of the vortex dynamics in a polariton condensate beyond the mean field theory
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - FísicaDepartamento de FísicaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2020)
This work is pretended to carry out an extensive review of concepts regarding Bose-Einstein condensates, polaritonics and vortex identification methods in order to theoretically grasp on the fundamentals of vortex dynamics ...
