Spectroscopies of quantum materials


List of members | Site d’équipe

Materials recently discovered present new electronic states which cannot be discribed with usual theories. In our team in Laboratoire de Physique des Solides, we explore these states using in particular Nuclear Magnetic Resonance.

Research topics

- high-Tc cuprates
- impurities
- correlated fermions
- frustration
- spin glasses
- metal insulator transitions
- fullerenes
- fullerene polymers
- frustrated magnetic systems
- slow dynamics in spin glasses
- tunneling states in quasicrystals
- strongly correlated fermions

Experimental methods

- muSR
- angle-resolved photoemission spectroscopy
- infrared spectroscopy
