ProjectsMy research concentrates on disordered, frustrated and out-of-equilibrium systems, mostly in quantum condensed matter, but also in classical systems. An important part of my work is concerned with a wide variety of disordered and strongly interacting systems such as semiconductors, superconductors, cold atomic gases quantum spin glasses and disordered magnets. These structurally complex systems host a wealth of interesting phenomena, not present in standard ordered matter, namely: Quantum localization, non-trivial ergodicity breaking, dynamics far off equilibrium, memory effects, etc. The interplay of interactions, disorder and quantum fluctuations is very rich, and raises questions of fundamental nature in quantum statistical physics.
I am a member of the Quantum Technology Collaboration (QTC@PSI).
I am coordinating and organising the CMT Seminars, CM Colloquia and PSI Colloquia.
