Microscopic description of dielectric thermal transport with memory and nonlocal effects

Autor: Sendra Molins, Lluc

Aquesta tesi proporciona un nou formalisme per resoldre l'equació de transport de Boltzmann per fonons per a nombres de Knudsen finits que proporciona una equació hidrodinàmica de transport de calor, l'equació de Guyer i Krumhansl, similar a l'eq

We report the spin dynamic properties of non-substituted ferrocenium complexes. Ferrocenium shows a field-induced single-molecule magnet behaviour in DMF solution while cobaltocene lacks slow spin relaxation neither in powder nor in solution. Multire

Microscopic modeling of exciton polarons in 2D perovskites

Autor: Álvarez Pérez, Guillem

Publikováno v: UPCommons. Portal del coneixement obert de la UPC
Universitat Politècnica de Catalunya (UPC)

Debido al reducido apantallamiento dieléctrico en materiales 2D, fuertes interacciones de Coulomb aparecen entre electrones y agujeros, formando así las cuasi-partículas conocidas como excitones. Estos tienen un peso determinante en relación con

[EN] Spontaneous locking of the phase of a coherent phonon source to an external reference is demonstrated in a deeply sideband-unresolved optomechanical system. The high-amplitude mechanical oscillations are driven by the anharmonic modulation of th

Giant thermal enhancement of the electric polarization in ferrimagnetic BiFe_{1-x}Co_{x}O_{3} solid solutions near room temperature

Thermal excitations typically reduce the electric polarization in ferroelectric materials. Here, we show by means of first-principles calculations that multiferroic BiFe$_{1-x}$Co$_{x}$O$_{3}$ solid solutions with $0.25 \le x \le 0.50$ (BFCO) represe

The electronic structure of AgCuO2, and more specifically the possible charge delocalization and its implications for the transport properties, has been the object of debate. Here the problem is faced by means of first-principles density functional t

The Raman modes of α-quartz-type boron phosphate were found to be extremely stable in frequency over a large temperature range from 300–1000 K. In order to determine the origin of this behavior, the material was also studied at high pressure up to
