Two-component Bose-Einstein condensates with competing interactions
(Universitat Politècnica de Catalunya, 2020-02-10)
Doctoral thesis
Open AccessThis thesis reports the experimental study of two-component Bose-Einstein condensates with tunable interactions, which are exploited as a platform to perform quantum simulation of many-body quantum systems. To perform ... -
Spectral response of individual molecules and nanoantennas with two-beam excitation
(Universitat Politècnica de Catalunya, 2020-02-21)
Doctoral thesis
Open AccessAt room temperature, individual molecules can be found in different conformations due to intrinsic and extrinsic factors which are reflected in spectral variability. When detecting single molecules, the ensemble average ... -
Plasmon-electron interactions in low dimensional materials
(Universitat Politècnica de Catalunya, 2020-02-17)
Doctoral thesis
Open AccessEver since the advent of modern technology, major developments have come hand in hand with miniaturization and speed of operation. A proof of this is provided by the impressive success of Moore's law, which predicted that ... -
Polaron physics in carbon nanotube electro-mechanical resonators
(Universitat Politècnica de Catalunya, 2020-02-06)
Doctoral thesis
Open AccessCarbon nanotube (CNT) mechanical resonators are unique systems because they combine remarkable mechanical properties with rich charge transport characteristics. Thanks to their intrinsically low-dimensional nature, their ... -
Quantum Brownian motion in Bose-Einstein condensates
(Universitat Politècnica de Catalunya, 2020-01-31)
Doctoral thesis
Open AccessQuantum Brownian motion is one of the most prominent examples of an open quantum system, a system which cannot be treated in isolation from its environment. The simplest method to study the dynamics of a system undergoing ... -
Development of a high intensity Mid-Ir OPCPA pumped by a HO:YLF amplifier
(Universitat Politècnica de Catalunya, 2020-01-27)
Doctoral thesis
Open AccessThe continuous development of laser sources delivering ultra-short light pulses underpins much of the current progress in experimental science, particularly in the domain of physics concerned with strong-field phenomena. ... -
From cells to tissues, microscopy to modeling: towards precise, data-driven photothermal therapy with gold nanorods
(Universitat Politècnica de Catalunya, 2019-02-15)
Doctoral thesis
Open AccessSuspensions of gold nanorods (GNRs) are emerging as potential drugs to address some of the limitations in traditional biomedical sensing,imaging and therapy. They are inorganic nanoparticles with good biocompatibility, ... -
Quantifying nanoscale carrier diffusion with ultrafast optical and photocurrent microscopy
(Universitat Politècnica de Catalunya, 2019-09-06)
Doctoral thesis
Restricted access - author's decisionHeat transport in solids is one of the oldest problems in physics, dating back to the earliest formulations of thermodynamics. The classical laws of heat conduction are valid as long as the observed time and length scales ... -
Quantum information outside quantum information
(Universitat Politècnica de Catalunya, 2019-10-15)
Doctoral thesis
Open AccessQuantum theory, as counter-intuitive as a theory can get, has turned out to make predictions of the physical world that match observations so precisely that it has been described as the most accurate physical theory ever ... -
Time domain, near-infrared diffuse optical methods for path length resolved, non-invasive measurement of deep-tissue blood flow
(Universitat Politècnica de Catalunya, 2019-10-04)
Doctoral thesis
Open AccessThe non-invasive and, often, continuous measurement of the hemodynamics of the body, and for the main purposes of this thesis, the brain, is desired because both the instantaneous values and their changes over time constantly ... -
Charge carrier dynamics and interfaces in perovskite solar cells
(Universitat Politècnica de Catalunya, 2019-07-30)
Doctoral thesis
Open Access
Covenantee: Karlsruher Institut für TechnologieOrganometal halide perovskites for solar cells are hybrid semiconductors that recently have caught the attention of the scientific community due to its excellent performance and attractive optical properties. Since then, ... -
