A Monte Carlo approach to statics and dynamics of quantum fluids

Ferré Porta, Guillem (Date of defense: 2017-09-16)

The main objective of the thesis is to study static and/or dynamic properties of a set of quantum fluids by means of quantum Monte Carlo techniques, mainly using the path integral formalism to obtain results both at zero ...

Nuevas aproximaciones al estudio de la dinámica de la relajación dieléctrica en ferroeléctricos ordinarios y relajadores

Levit Valenzuela, Rafael (Date of defense: 2019-12-10)

Ferroelectric materials are endowed with fascinating functional properties from the technological point of view. Consequently, they have promoted the design of ferroelectric-based devices with applications in a vast range ...

Propiedades vitreas emergentes en cristales moleculares

Gebbia, Jonathan Fernando (Date of defense: 2021-10-06)

One of the most complex and unsolved problems in physics is the glass transition problem, in which the resulting state, the glass, exhibits unique and anomalous properties. During the transition, a kinetic freezing phenomenon ...
