Biography

I am a condensed matter theorist. My research concerns many aspects of correlated systems in condensed matter and quantum gases among which
– New topological states of matter such as topological insulators and superconductors and their  exotic excitations such as Majorana zero modes.
– Transport in correlated nanosystems and its non-equilibrium features (includes hybrid electronic-cavity QED systems)
– Strongly correlated quantum systems in low dimensions.

I am mainly using analytical methods based on effective models, quantum field theory, such as diagrammatics, renormalization group approaches, etc.

Interests

  • Topological states of matter
  • New exotic excitations
  • Transport in correlated systems
  • Light&Matter interaction
  • Low-dimensional correlated systems

Education

  • Master in theoretical physics, ENS Paris.
  • PhD in theoretical physics, University Paris Sud (1998).
  • Habilitation thesis, Joseph Fourier University, Grenoble (2003).
