Efficient update of determinants for many-electron wave function overlaps
(2021-01)
Article
Accés obertThe calculation of overlaps between many-electron wave functions at different nuclear geometries during nonadiabatic dynamics simulations requires the evaluation of a large number of determinants of matrices that differ ... -
Eina de representació de funcions d'ona quàntiques en 3D
(Universitat Politècnica de Catalunya, 2022-10-18)
Treball Final de Grau
Accés obertLa física quàntica és un tema molt complex, que és la base per a la comprensió dels fenòmens naturals. Aquesta explica elements com l'àtom, l'enllaç químic... Ara bé, encara que descriu el món en una escala atòmica podem ... -

Pattern and velocity selection of fronts propagating in modulated media
(EDP Sciences, 1996-02-01)
Article
Accés obertWe study the problem of pattern and velocity selection of morphologically stable two-dimensional fronts propagating in a spatially modulated medium. The generic system is governed by a local equation and evolves towards a ... -
Quantum particles in fractal external potential
(Universitat Politècnica de Catalunya, 2021-06-28)
Treball Final de Grau
Accés obertThe Schrödinger equation gives us a time evolution of the wave function of a certain quantum system, thus we obtain a mathematical description of this system. This project focuses on solving it numerically, using the exact ... -
Quantum versus mean-field collapse in a many-body system
(2015-10-29)
Article
Accés obertThe recent analysis, based on the mean-field approximation (MFA), has predicted that the critical quantum collapse of the bosonic wave function, pulled to the center by the inverse-square potential in the three-dimensional ...
