In this thesis, a single-atom trap in a "Maltese cross'' geometry (MCG) was designed, built up and characterized. A MCG atom trap uses four in-vacuum lenses to achieve four-directional high-numerical-aperture ...
Understand and tame complex quantum mechanical systems to build quantum technologies is one of the most important scientific endeavour nowadays. In this effort, Atomic, molecular and Optical systems ...
Quantum Mechanics was established as the theory of the microscopic world, which allowed to understand processes in atoms and molecules. Its emergence led to a new scientific paradigm that quickly spread ...
In this thesis, we develop a general theory to describe the dynamics of electrons that are ionized when an atom or molecule is exposed to a strong low frequency laser field. Our approach extends and ...
One of the grand challenges of modern science is to image chemical reactions and biological functions while they are taking place. To realize these molecular movie, experimental techniques need to resolve ...
Carbon nanotube (CNT) mechanical resonators are unique systems because they combine remarkable mechanical properties with rich charge transport characteristics. Thanks to their intrinsically low-dimensional ...
At sufficiently low temperatures, fluids of bosonic particles may undergo a phase transition, below which a Bose-Einstein condensate (BEC) forms. The BEC is one of the most fundamental concepts in ...
The arrival of super-resolution techniques has driven researchers to explore biological areas that were unreachable before. Such techniques not only allowed the improvement of spatial resolution in ...
Understanding and improving how light is converted into electricity in materials is one of the central goals in the field of optoelectronics. This basic physical process lies at the heart of several ...
The outstanding progress achieved in the last decades to isolate and manipulate individual quantum systems has revolutionized the way in which quantum many-body phenomena, appearing across Nature's ...
