Dhara, Chirag (Data de defensa: 2013-06-12)
Quantum mechanics was developed as a response to the inadequacy of classical physics in explaining certain physical phenomena. While it has proved immensely successful, it also presents several features that severely ...
Randhawa, Sukanya (Data de defensa: 2012-12-04)
Plasmonics nanostructures are becoming remarkably important as tools towards manipulating photons at the nanoscale. They are poised to revolutionize a wide range of applications ranging from integrated optical circuits, ...
Grass, Tobias (Data de defensa: 2013-04-23)
The present thesis studies a variety of cold atomic systems in artificial gauge fields. In the first part we focus on fractional quantum Hall effects, asking whether interesting topological states can be realized with cold ...
Jofre Cruanyes, Marc (Data de defensa: 2013-04-15)
An important issue in today's information society is the security of data transmission against potential intruders, which always put at risk the confidentiality. Current methods to increase security require that the two ...
Hauke, Philipp Hans-Jürgen (Data de defensa: 2013-04-05)
Many outstanding problems in quantum physics, such as high-Tc superconductivity or quark confinement, are still - after decades of research - awaiting commonly accepted explanations. One reason is that such systems are ...
Aviles-Espinosa, Rodrigo (Data de defensa: 2013-03-27)
The requirement for imaging living structures with higher contrast and resolution has been covered by the inherent advantages offered by nonlinear microscopy (NLM). However, to achieve its full potential there are still ...
Tieleman, Olivier (Data de defensa: 2013-03-08)
This thesis contains theoretical research on ultracold quantum gases in spatially periodic potentials, featuring high-frequency periodic driving, long-range interactions, or both. The largest part features deep potentials ...
Prettico, Giuseppe (Data de defensa: 2013-01-18)
Quantum Information Theory (QIT) studies how information can be processed and transmitted when encoded on quantum states. Practically, it can be understood as the effort to generalize Classical Information Theory to the ...
Acomovic, Srdjan S. (Data de defensa: 2012-10-30)
In recent times, metallic nanoparticle plasmonics coupled with applications towards biosensing has gathered momentum to the point where commercial R&D are investing large resources in developing the so-called localized ...
Raj, Saurabh (Data de defensa: 2012-11-05)
This thesis is devoted to the study of mechanochemistry of single cells and single biomolecules. Mechanochemistry relates to the association of mechanical and chemical occurrence at the molecular level. Using a combination ...
Gallego López, Rodrigo (Data de defensa: 2013-02-22)
The device-independent formalism is a set of tools to analyze experimental data and infer properties about systems, while avoiding almost any assumption about the functioning of devices. It has found applications both in ...
Wolfgramm, Florian (Data de defensa: 2012-06-29)
The use of light, especially of laser light, is in many cases the most sensitive way to perform measurements. However, the highest sensitivity that can be achieved with laser light as probe is bounded by the standard quantum ...
Brinks, Daan (Data de defensa: 2012-10-19)
Ultrafast pulses allow observation of molecular dynamics with femtosecond time resolution through pump probe experiments. However, averaging over an ensemble of molecules tends to wash out phase sensitive information, ...
Neumann, Lars (Data de defensa: 2012-04-18)
Un tema central en la ciencia y la tecnología es la exploración y explotación de sistemas cada vez más pequeños por medio de técnicas ópticas. A menudo, la longitud de onda viene dictada por el sistema de interés: los ...
Volpe, Giorgio (Data de defensa: 2012-05-10)
El control dinámico y determinístico de la luz en una escala espacial por debajo de la longitud de onda es un requisito clave para ampliar los conceptos y las funcionalidades de la macro-óptica hasta la escala nanométrica. ...
Chaitanya Kumar, Suddapalli (Data de defensa: 2012-01-18)
High-power, continuous-wave (cw), mid-infrared (mid-IR) laser sources are of interest for variety of applications such as trace gas detection and remote sensing, which require broad spectral coverage to address the most ...
Yudistira, Didit (Data de defensa: 2012-02-21)
In this thesis we have investigated and proposed acoustic superLattices (ASLs) made of periodically poled ZX-cut lithium niobate (PPLN) associated ith coplanar electrodes as an effective alternative for surface acoustic ...
Tulli, Domenico (Data de defensa: 2012-02-20)
A material that is enabling integrated optics is the ferroelectric crystal Lithium Niobate (LiNbO3), which has excellent electro-optical, acousto-optical and nonlinear optical properties. Moreover, it can be doped with ...
Braungardt, Sibylle (Data de defensa: 2011-07-12)
Samanta, Goutam Kumar (Data de defensa: 2009-07-01)
This thesis presents the development of a new class of high-power, continuous-wave (cw) optical parametric oscillators (OPOs) with extended tunability from visible to near-infrared (near-IR). While lasers have been in use ...
