Charge and spin transport in graphene devices
(2015-06-05)
El grafeno es una capa bidimensional (2D) de átomos de carbono conectadospor enlaces ¿¿¿¿2. Electrónicamente el grafeno es un semi-metal sin bandaprohibida con una relación de dispersión lineal para bajas densidades ...
New generation of two-dimensional spintronic systems realized by coupling of Rashba and Dirac fermions
(Nature Publishing Group, 2015-08-04)
Intriguing phenomena and novel physics predicted for two-dimensional (2D) systems formed by electrons in Dirac or Rashba states motivate an active search for new materials or combinations of the already revealed ones. Being ...
Theory and simulation of the optical response of novel nanomaterials from visible to terahertz
(2015-07-09)
Los avances tecnológicos ocurridos a partir del siglo XVI han permitido explorar tanto
el mundo microscópico como el macroscópico, gracias al desarrollo de dispositivos
basados en lentes y espejos, desconocidos hasta ...
Density-potential mapping in the standard and quantum electrodynamical time-dependent density functional theory
(2015-10-30)
This thesis is devoted to the formulation and implications of the time-dependent density functional theory (TDDFT). The work is divided into two main parts. In the first part we develop rigorous theorems for the density-potential ...

The role of H-bonds on the structure and dynamics of very concentrated polymer solutions
(2015-10-02)
El proposito de la presente tesis doctoral es determinar como la presencia de moleculas de disolventes afecta las dinamicas de un polmero en diferentes escalas temporales y espaciales y como la dinamica del disolvente esta ...
Spin orbitronics in metals
(2015-12-10)
El trabajo realizado en esta tesis se centra en el estudio de la inyección,transporte y detección de corrientes puras de espín en metales. Una de lasmaneras para crear y detectar estas corrientes es utilizando electrodos ...
Spectroscopic analysis of atoms and molecules
(2015-09-11)
En esta tesis he estudiado varios aspectos de la respuesta espectroscópica de varios átomos y moléculas a una fuente electromagnética externa. Entender dicha respuesta cuántica tanto nuclear como electrónica es muy complicado, ...
Response of the topological surface state to surface disorder in TlBiSe2
(IOP Publishing, 2015-02-24)
Through a combination of experimental techniques we show that the topmost layer of the topological insulator TlBiSe2 as prepared by cleavage is formed by irregularly shaped Tl islands at cryogenic temperatures and by mobile ...
Collective dynamics of glass-forming polymers at intermediate length scales: a synergetic combination of neutron scattering, atomistic simulations and theoretical modelling
(EDP Sciences, 2015)
Motivated by the proposition of a new theoretical ansatz [V.N. Novikov, K.S. Schweizer, A.P. Sokolov, J. Chem. Phys. 138, 164508 ( 2013)], we have revisited the question of the characterization of the collective response ...
