Spectral phase control of nanoscale nonlinear optical responses
The study of light-driven physical processes generated in nanomaterials require shorter (in time, or broader in frequency) laser pulses with techniques to tailor its phase and temporal/spectral characteristics at the ...
Levitation and control of particles with internal degrees of freedom
Levitodynamics is a fast growing field that studies the levitation and manipulation of micro- and nanoobjects, fuelled by both fundamental physics questions and technological applications. Due to the isolated nature of ...
Imaging cytometry technology for environmental and biomedical applications
Early detection of microorganisms in environmental and biomedical applications is critical for the effective response to potential pathogenic treats. Most traditional methods and instrumentation for the analysis of these ...
Exploring quantum many-body systems from an entanglement and nonlocality perspective
Entanglement and non-local correlations give rise to unprecedented phenomena with no classical analogue. As a result, they have settled themselves as fundamental properties in the study of quantum many-body systems, as ...
Investigations of topological phases for quasi-1D systems
For a long time, quantum states of matter have been successfully characterized by the Ginzburg-Landau formalism that was able to classify all different types of phase transitions. This view changed with the discovery of ...
Novel continuous-wave infrared parametric sources and noise analysis of infrared upconversion detectors
The ability to manipulate frequency of light, through parametric frequency conversion sources based on X(2) nonlinear materials, offers an effective route to spectral regions unapproachable by conventional lasers. Most ...
Study of graphene hybrid heterostructures for linear and nonlinear optics
Graphene is the first of the 2D-material family. It is formed by carbon atoms arranged in a honeycomb lattice, which confers it intriguing physical properties that are still being discovered nowadays. A fundamental advantage ...
Levitodynamics on-a-chip: from planar Paul traps to near-field optical nanocavities
The field of levitation optomechanics---or levitodynamics---studies the manipulation and control of small trapped objects in an isolated environment, providing a gateway to answer fundamental questions in physics and ...
Development and application of localization-based microscopy methods to study the structure and dynamics of chromatin through the process of cellular differentiation
Recent advancements in single-molecule localization-based microscopy have made it possible to visualize biological structures and dynamic processes within the cell with unprecedented spatial resolution. Determining the ...
Entanglement and Bell correlations in strongly correlated many-body quantum systems
During the past two decades, thanks to the mutual fertilization of the research in quantum information and condensed matter, new approaches based on purely quantum features without any classical analog turned out to be ...
Ultrafast carrier and structural dynamics in graphite detected via attosecond soft X-ray absorption spectroscopy
Understanding most of the physical and chemical phenomena determining the world around us requires the possibility to interrogate their main characters on their natural scale in space and time. The insulating or conductive ...
Two-component Bose-Einstein condensates with competing interactions
This 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
At 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
Ever 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
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 nature, their ...
Development of a high intensity Mid-Ir OPCPA pumped by a HO:YLF amplifier
The 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. ...
Quantum Brownian motion in Bose-Einstein condensates
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 a system undergoing ...
From cells to tissues, microscopy to modeling: towards precise, data-driven photothermal therapy with gold nanorods
Suspensions 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
Heat 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
Quantum 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 ...
