Antiparticle Contribution in the Cross Ladder Diagram for Bethe-Salpeter Equation in the Light-Front
(Springer/plenum Publishers, 2009-11-01)
We construct the homogeneous integral equation for the vertex of the bound state in the light front with the kernel approximated to order g(4). We will truncate the hierarchical equations from Green functions to construct ...

Cross-Ladder Diagrams Via Hierarchical Equations in the Light Front
(Springer, 2015-09-01)
We calculate the correction to the propagator of two bosons up to the g (4) order in the cross-ladder approximation in the light front. The hierarchy of the coupled equations describe the propagator of two bosons in various ...
Nonperturbative effective-field theory for two-leg antiferromagnetic spin ladders
(American Physical Society, 2001-12)
We study the long wavelength limit of a spin- 2 Heisenberg antiferromagnetic two-leg ladder, treating the interchain coupling in a nonperturbative way. We perform a mean field analysis and then include the fluctuations in ...
Simulación de las propiedades energéticas, termodinámicas y espectroscópicas de moléculas nanoconfinadas
(Universidad Nacional de ColombiaConsejo Superior de Investigaciones Científicas (CSIC)Bogotá - Ciencias - Doctorado en Ciencias - FísicaDepartamento de FísicaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022-07-01)
El desarrollo de modelos y metodologías destinadas a entender las peculiaridades de ciertas estructuras moleculares confinantes, como clatratos, endofullerenos y nanogotas, tiene consecuencias directas en el campo de las ...
