Building up a frequency stabilisation based on a wavemeter for a diode laser and characterisation for a digital mirror device for artificial potentials
Beldarrain Ruiz de Azua, Aitor (2016-04-27)It has built and characterised a laser and It has learned what each of the components does. It has been able to run the laser in single-mode and stabilised it around a desired setpoint thanks to a PID controller that It ... -
Denbora Fisikan
Ondaro Mallea, Lurdes (2020-01-16)[EUS] Denbora oso presente dago egunerokoan. Etengabe darabilgu egitekoak antolatzeko: noiz jaiki,noiz den autobusa, zein ordutatik zein ordutara egin lan, noiz jan, noiz oheratu. Erlojuaren menpe bizi garela esatea ez da ... -
Double proximity effect in lateral S-NF-S junctions
Peña Darriba, Andrea (2016-04-27)We investigate planar Josephson junctions where the intermediate spacer between the two superconductors is an hybrid structure made by a normal metal and a ferromagnet. The different behaviors of the S-N-S junctions with ... -
Fluorescence cross-correlation spectroscopy to study hemodynamics
Villa Abaunza, Amaia (2016-04-28)[EN] In the recent years a series of optical correlation techniques have been developed in order to be able to measure flow velocity with high spatial resolution while being non-invasive in order to be employed in-vivo ... -
Generalized Geometry for Relativistic Theories of Gravity
Royo Abrego, Andoni (2020-12-15)[EN] The TGR is constructed over a Pseudo-Riemaniann manifolod, where the torsion is assumed to vanish. However, there is not any physical argument behind it and when torsion is allowed, the spacetime in which the theory ... -
Inflazio kosmikoaren Fisika: Unibertsoaren egituraren jatorri kuantikoa
Azcona Iribar, Julen José (2016-04-28)[ES] Analizamos el modelo de inflación cósmica más sencilla, y cómo este, a la vez que soluciona los problemas del modelo cosmológico estándar, es capaz de explicar el origen de la estructura a gran escala del universo. -
Inflazio kosmologikoa eta Kosmologia Zikliko Konformea Big Bang beroaren arazoen konponbide gisa
Estonba Loinaz, Julen (2024-05-10)[EU] Lan honetan Big Bang beroaren ereduak dituen arazoak ebazteko bi teoria aurkezten dira: Inflazio kosmologikoa eta Kosmologia Zikliko Konformea. Inflazio kosmologikoak unibertso goiztiarrean hazkuntza esponentzial bat ... -
Materia iluna eta bere beharraren eztabaida: NGC1052-DF2 eta NGC1052-DF4 galaxiak
Pérez Arrieta, Mikel (2020-12-15)[EUS] Gradu amaierako lan honen helburua materia ilunaren beharra eta honen inguruan dagoen eztabaida ulertzea da. Lehenik eta behin, materia ilunaren existentziaren ebidentziak aipatzen dira, hauetatik materia barionikoaz ... -
Memoria asociativa en redes tipo Hopfield balanceadas
Recio Marín, Ibon (2016-04-28)[ES] Análisis computacional de un modelo (además de su fenomenología emergente) de red asociativa tipo Hopfield que se ha modificado para de cabida a evidencias biológicas como es la del balanceado entre las neuronas ... -
PLANCK sateliteak behatutako fisika: mikrouhin erradiazio kosmikoaren (CMB) tenperatura anisotropien azterketa
Arregi León, Unai (2020-01-16)[EUS] Unibertsoaren jatorriaren eta hedapenaren inguruan teoria mordoa proposatua izan da historian zehar, eta gaur egun oraindik ere etengabeko eztabaidan dauden ideia eta proposamen ugari dago kosmologoen artean. Dena ... -
Planeten formazioa
Gurrutxaga Asiain, Nerea (2021-12-03)[EUS] Lan honen helburua planeten formazioaren inguruko ideia orokorrak lantzea da, baita gaur egungo ikerkuntzaren egoera eta erronkak ulertzeko gai izatea ere. Horretarako, lehenengo ezinbestekoa da unibertsoan existitzen ... -
Random matrix theory eta aplikazioa kaos kuantikoan
Iparragirre Apraiz, Itsasne (2016-07-20)[eus] Gradu amaierako lan honetan ausazko matrizeen teoriari, RMT-ri, buruzko sarrera orokor bat egiten da ondoren aplikazio fisiko bat emateko. Teoriaren aplikazioa egiteko Kaos kuantikoa deritzon fisikaren arloa erabiliko ... -
Spectroscopic study of galaxies in the Herschel Reference Sample
Fernández Otegui, Jon (2016-04-28)Galaxies are clusters of millions and billions of stars dynamically stable, with gas, dust and dark matter. They are the biggest isolated objects known in the Universe . Even though they are very complex systems, today we ... -
Surface plasmons and effects of losses in propagating modes in a chain of silver nanoparticles
Inchausti Ezeiza, Xabier (2016-04-28)In this work a chain of 4000 silver nanoparticles embedded in a glass medium is considered, and its leftmost particle is excited by an electric field pulse of Gaussian shape. Considering Drude’s model, losses of the ... -
The propagation of nerve pulses: From the Hodgkin-Huxley model to the soliton theory
Morcillo García, Ana Belén (2014-06-23)The present project aims to describe and study the nature and transmission of nerve pulses. First we review a classical model by Hodgkin-Huxley which describes the nerve pulse as a pure electric signal which propagates due ...
