Perturbative method for generalized spectral decompositions
Imposing analytic properties to states and observables we construct a
perturbative method to obtain a generalized biorthogonal system of eigenvalues
and eigenvectors for quantum unstable systems. A decay process can be described
using this generalized spectral decomposition, and the final generalized state
is obtained.Comment: 21 Page
Inestabilidad cuántica en el potencial de David Bohm
En este trabajo resumimos una estructura explícita de cálculo numérico para resolver el formalismo de David Bohm de la Mecánica Cuántica. El programa fue desarrollado en Fortran 77 para correr en equipos PC de capacidad estándar. Mostramos numéricamente la existencia de la inestabilidad cuántica en el potencial de David. Bohm cuando los estados estacionarios son ligeramente perturbados. Para los estados perturbados el espacio de las fases asociado a la partícula virtual presenta aspecto caótico.Eje: Workshop sobre Aspectos Teoricos de la Inteligencia ArtificialRed de Universidades con Carreras en Informática (RedUNCI

White paper: from bound states to the continuum
International audienceThis white paper reports on the discussions of the 2018 Facility for Rare Isotope Beams Theory Alliance (FRIB-TA) topical program ‘From bound states to the continuum: Connecting bound state calculations with scattering and reaction theory’. One of the biggest and most important frontiers in nuclear theory today is to construct better and stronger bridges between bound state calculations and calculations in the continuum, especially scattering and reaction theory, as well as teasing out the influence of the continuum on states near threshold. This is particularly challenging as many-body structure calculations typically use a bound state basis, while reaction calculations more commonly utilize few-body continuum approaches. The many-body bound state and few-body continuum methods use different language and emphasize different properties. To build better foundations for these bridges, we present an overview of several bound state and continuum methods and, where possible, point to current and possible future connections
From bound states to the continuum
International audienceOne of the biggest and most important frontiers in nuclear theory today is to construct better and stronger bridges between bound state calculations and calculations in the continuum, in particular scattering and reaction theory, as well as teasing out the influence of the continuum on states near threshhold. This is particular challenging as most many-body calculations are in a bound state formalism, while reaction calculations are more commonly in a few-body formalism. Furthermore many-body and few-body formalisms often use different language and emphasize different properties. To build better foundations for these bridges, we present an overview of bound state and continuum methods and, where possible, point to current and possible future connections
