Here we will show our first calculations in which we are able to resolve the electron dynamics around the Dirac points of graphene by using x-ray attosecond transient absorption spectroscopy.

We will discuss the dynamics of classical and quantum many-body systems in the presence of constraints. This is understood in a really broad sense of the term, ranging from lattice gauge theories, over fractonic systems to general spatially-modulated symmetries.

In this talk, we will review the science behind anti-resonant fibre technology and discuss two recent examples of its multiple applications.

The critical current of a superconductor can depend on the direction of current flow due to magnetochiral anisotropy when both inversion and time-reversal symmetry are broken, an effect known as the superconducting (SC) diode effect.

La luz comprimida en amplitud es un tipo de luz cuántica en la que una de las cuadraturas tiene fluctuaciones menores que el vacío. Se trata de un recurso esencial tanto en metrología cuántica como en información cuántica.

We numerically examine the transition from integrability to chaos when the inter-component interaction changes from weak to strong.

In this talk, we are going to review our contributions to this field, with focus on SAW-driven photonic devices. Finally, we will discuss our recent contribution on the manipulation of single photons generated on a chip by SAWs.

We will compare the master equation predictions against individual realizations with reference to a paradigmatic light-matter interaction formulation, the Jaynes- Cummings (JC) model.

In this talk, I will present how machine learning (ML) can enhance the quantum properties of Integrated photonic waveguides, photonic resonators, and single-photon emitters, specifically the indistinguishability (I) of the generated single photons, with a further decrease in quantum decoherence.

In this talk, I will report on acoustically driven spin transitions between the spin sublevels of silicon vacancy centers in SiC.

All fundamental particles have one of two forms of particle statistics: fermions or bosons. However, indistinguishable particles with exchange statistics intermediate between fermions and bosons can exist when particles are constrained to one or two dimensions.

Superconductivity, being a quantum phenomenon, manifests as the absence of electrical resistance when current flows, leading to significant macroscopic effects.

Optical vortex rings are loop-like structures with a rotational flow of energy around the nodal lines. We construct a model, which consists of the interference of the Gaussian beam and a 3D plane wave, that generates vortex rings

A diferencia del mundo físico, en los entornos digitales, la identidad y la presencia humanas pueden replicarse en las pantallas en forma de variadas representaciones de base digital. Cada persona del mundo físico puede desplegar múltiples representaciones de su identidad en el mundo digital y sus 'metaversos'.

The incorporation of metals into devices has taken integrated optics into the nanoscale but a the cost of having to deal with large power losses.After a brief presentation of the concept, interest and some examples of plasmonic systems, as well as a discussion of the pros and cons respect to conventional devices based on dielectrics, a description of basic integrated plasmonic devices as waveguides and couplers will be reviewed

Optical frequency combs in microresonators and associated dissipative solitons provide a compact, broadband, and low-noise light source and frequency measurement tool with consequences ranging from research to industry. While Kerr combs and dissipative Kerr solitons have attracted significant attention over the last decade, advances in integrated photonic platforms using materials with second-order nonlinearity have stimulated recent interest in dissipative quadratic solitons. Quadratic solitons engage researchers with rich physics and allow the generation of low-noise frequency combs in spectral regions that are otherwise difficult to access. In this talk I will discuss different kinds of combs and dissipative quadratic solitons, the experimental platforms that support their formation, and cover the underpinning physics and mathematical models. I will also summarise the new applications that these solitons offer.

In this talk I will explore recent advancements in addressing these challenges, with a focus on distributed quantum sensing. We will demonstrate how this approach can overcome the shot-noise limit for estimating arbitrary linear combinations of multiple phase shifts, provided that the non-classical probe state exhibits anti-squeezed quadrature variance. Furthermore, we compare the sensitivity bounds of this protocol to those achievable with d independent Mach-Zehnder interferometers, each probed with a non-classical state and a coherent state. Our findings reveal that while independent interferometers can match the sensitivity of the entangled protocol, they require d non-classical states instead of a single one, highlighting the resource efficiency of the entangled strategy.
