High-power, stable, high-repetition-rate, picosecond ultraviolet (UV) sources are of crucial importance for a variety of applications, such as atmospheric sensing, spectroscopy or optical data storage. ...
Moreno Mencía, David (Date of defense: 2021-11-22)
In the last decades, quantum materials have received much attention in the field of condensed matter physics due, in part, to their exotic properties. These are difficult to understand as they result ...
Steinlechner, Fabian (Date of defense: 2015-12-14)
The nonlocal correlations of entangled systems are a feature inherent to quantum theory that is fundamentally at odds with our common-sense notions of realism and locality. Additionally, entanglement ...

In this work we demonstrate the first realization of a comagnetormeter in the ultracold regime. In comparison to regular magnetometers, which are designed to maximize their magnetic field sensitivity, ...
Charalambous, Christos (Date of defense: 2020-01-31)
Quantum 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 ...
