Welcome to our website!
Our group is part of the Center for Theoretical Physics at
the Ecole Polytechnique
and the Institut Polytechnique de Paris.
We conduct theoretical research on strongly-correlated quantum matter, in connection to ultracold atom gases, quantum optics, and quantum simulation.
In a nutshell, our work aims at characterizing novel phases of matter and phase transitions in synthetic quantum matter, exploiting quantum information theory and its relation to condensed matter physics, and developing new theoretical approaches.

Opening of the summer school Dynamics and Disorder in Interacting Quantum Many-Body Systems far from Equilibrium
The Summer School, organized by Dmitry Abanin, Laurent Sanchez-Palencia, and Marco Schiro, is now open. It is one of two long schools (1 month) organized in Les Houches during the summer of 2019. The non-equilibrium dynamics of correlated quantum systems is currently one of the most active in quantum matter physics, at the interface of condensed matter, atomic physics, statistical physics, and complex systems. The experimental and theoretical progress of recent years has revolutionized this field with considerable challenges for quantum technologies. Lectures will be delivered by internationally renowned teachers:
Fabien Alet, Immanuel Bloch, Leticia Cugliandolo, Eugene Demler, Thierry Giamarchi, Mikhail Lukin, Subir Sachdev, Laurent Sanchez-Palencia, Jon Simon, Frank Verstraete, and Peter Zoller.
They will train a new generation of promising students and young researchers to this emerging field.

Special issue on Quantum Simulation
A special issue on quantum simulation, coordinated by Prof. Laurent Sanchez-Palencia, appeared this month on the Comptes-Rendus de Physique of the French Academy of Sciences.
Envisioned by Richard Feynman in the early 1980s, quantum simulation has received dramatic impetus thanks to the de- velopment of a variety of plateforms able to emulate a wide class of quantum Hamiltonians. During the past decade, most of the quantum simulators have implemented rather well-known models, hence permitting a direct comparison with theo- retical calculations and a precise benchmarking of their reliability. The field has now reached a maturity such that one can address difficult problems, which cannot be solved efficiently using classical algorithms. These advances provide unprece- dented opportunities to explore previously unreachable fields, test theoretical predictions, and inspire novel approaches.
The special issue makes a point on recent advances of the field and discusses perspectives via a selection of contributions in various areas from ultracold atoms and quantum optics to statistical physics and condensed matter.
