Research activities

The activity of the string-theory team is based on mathematical approaches to strings as well as on applications in the field of gravitation (black holes and cosmology) and phenomenology (models of particle physics). This programme includes the following:
- Construct supersymmetric models, with linear or non-linear realization of supersymmetry.
- Study the patterns of supersymmetry breaking.
- Understand the role of non-perturbative effects in strings or in effective field theories.
- Investigate the string origin of the cosmological constant and understand the transitions occurring during the cosmological evolution. 
- Propose alternative views on inflation and cosmological evolution, inspired by supergravity models.  
- Interpret the black-hole entropy in terms of micro-states. 
- Set a deeper relationship among amplitudes computed in string theory or in 
supergravity.
 
Finally, applications of the gauge-gravity holographic duality now embrace topics in condensed-matter, like vortex formation in superfluids, graphene, quantum phase transitions or superconductivity phenomena at high temperature, where the quasiparticle paradigm breaks down.
