A major topic in my theoretical work is inspired by the study of atomic systems, a quantum platform whose precise optical control offers unique opportunities in the study of many-body physics, simulation and metrology.
In real-life experiments, quantum systems are not isolated, but interact with their environment. Understanding how this dissipation takes place is fundamental to take imperfections into account, protect quantum communications, or optimally prepare a state of interest. Advances on the cooling and control of Rydberg atoms and dipolar molecules has also allowed the community to go beyond the local interactions often found in optical lattices. Following this opportunity, we have studied some of the interesting physical consequences that the presence of long-range interactions has for the thermalization, transport and topology of quantum systems, as well as new opportunities in the simulation of chemistry-related phenomena.
