Probing localization and quantum geometry by spectroscopy

Physical Review Research, 2019
The spatial localization of quantum states plays a central role in condensed-matter phenomena, ranging from many-body localization to topological matter.

Quantum transport in ultracold atoms

, 2015
Ultracold atoms confined by engineered magnetic or optical potentials are ideal systems for studying phenomena otherwise difficult to realize or probe in the solid state because their atomic interaction strength, number of species, density, and geometry ...

Synthetic topological Kondo insulator in a pumped optical cavity

New Journal of Physics, 2018
Motivated by experimental advances on ultracold atoms coupled to a pumped optical cavity, we propose a scheme for synthesizing and observing the Kondo insulator in Fermi gases trapped in optical lattices.

Nonequilibrium quantum dynamics in ultracold quantum gases [PDF]

, 2016
Advances in controlling and measuring systems of ultra-cold atoms provided strong motivation to theoretical investigations of quantum dynamics in closed many-body systems. Fundamental questions on quantum dynamics and statistical mechanics are now within experimental reach: How is thermalization achieved in a closed quantum system?

Ultracold atomic gases for hybrid quantum systems

Frontiers in Optics 2012/Laser Science XXVIII, 2012
Ultracold atomic gases have long held promise as a quantum many-body resource for field and force metrology. A powerful route to extend such quantum-limited sensors to sub-micron length scales is to interface the atomic gas to an optomechanical device creating a 'hybrid quantum system'.

Expansion Dynamics of Rydberg-Dressed Ultracold Fermi Gas

Photonics
We present a theoretical investigation into the expansion dynamics of Rydberg-dressed ultracold Fermi gases. The effective interaction potential induced by Rydberg dressing significantly modifies the intrinsic properties and dynamical behavior of the ...

Disordered ultracold quantum gases

Localisation in condensed matter physics is one of the pillars of understanding the transport properties of materials, like conductivity in solids.In this thesis, we explore Anderson localisation of a Fermi gas in a 2D disordered media of point-like scatterers, using the propagator's formulation of quantum mechanics.
