Nicola Bartolo

**Ph.D. in Theoretical Physics**

The Short Story

I'm a young and motivated Post-doc in Physics with a great passion for science and scientific research. My interests fall in the framework of theoretical physics, but keeping an eye on experimental realizations and practical applications.

Currently, I'm a

**Postdoc**researcher in the Theory group of the MPQ Lab (University of Paris Diderot), directed by Prof. C. Ciuti. My long-term objective is to find a position as a researcher on stimulating subjects, preferably with some development prospective in the technological field.Research Fields

**Interacting Photons****Photons**, which barely interact in vacuum,**inherit**a considerable matter-mediated**interaction**in nonlinear media. This allows to realize photonic**many-body quantum systems**, which raised a tremendous interest in the last decades. These systems, being intrinsically out-of-equilibrium, result in a more complex but also richer physical scenario with respect to their equilibrium counterparts.I focus my activities on the study of one or several sites of

**nonlinear cavities lattices**, using quasi-analytical methods and/or numeric techniques. Moreover, I investigate how the behavior of a**condensed matter system**can be modified by the light-matter coupling when it is**embedded in an optical cavity**.[Picture: a semiconductor microcavity embedding a quantum well (source)]

**Ultracold Gases**Since the achievement of

**Bose-Einstein condensation**in 1995 the field of ultracold quantum gases has been one of the most flourishing both in theoretical and experimental physics. Matter can now reach new phases in which its*wavelike*nature takes over the particle behavior.In particular, my researches address the behavior of

**matter waves in periodic potentials**generated by optical lattices or by trapped atoms. Such systems are promising candidates in the**quantum simulation**of condensed matter systems or in the investigation of fundamental properties of the interatomic interactions, such as the**dipole-dipole interaction**.[Picture: quantum phase transition for cold atoms in an optical lattice (source)]

**Vacuum Forces**An impressive consequence of the

*quantumness*of the electro-magnetic field is the existence of vacuum effects related to the**zero-point fluctuations**of the field. Such effects appear, for instance, as vacuum forces in the**Casimir**and**Casimir-Polder**effects. Such forces, appearing at the nanoscale, are more and more important for technological applications in miniaturized devices.In this field I am interested in the

**fundamental properties**of the energy density of the field in the vicinity of material-to-vacuum interfaces. I also study how to**tailor the atom-wall forces**by means of laser-excited surface plasmons and polaritons.[Picture: pictorial view of the Casimir effect (source)]
