Many-body systems with both coherent dynamics and dissipation constitute a rich class of models which are nevertheless much less explored than their dissipationless counterparts. The advent of numerous experimental platforms that simulate such dynamics poses an immediate challenge to systematically understand and classify these models. [more]

Many large-scale, universal, effects in one-dimensional systems at quantum critical points can be tackled with a combination of methods from solvable lattice models and from field theory, usually conformal field theory (CFT) and Luttinger liquid ideas. [more]

I will discuss two research lines I'm developing. [more]

Trapping ultracold atoms in optical lattices enabled numerous breakthroughs uniting several disciplines. Although light is a key ingredient in such systems, its quantum properties are typically neglected, reducing its role to a classical tool for atom manipulation. [more]

Tests of quantumness are experiments which enable us to exclude the possibility of modeling them with classical means. They enable us to prove strong statements about the nature of the universe and obtain cryptographic protocols with an unprecedented level of security. [more]
