Current Research Interests (2019)
Effective Field Theories of Topological States of Matter
- Conformal field theories describing edge excitations in the fractional
quantum Hall effect
- Experimental signatures of fractional statistics in 2D
- Stability of topological phases of matter in 2D and 3D
- Surface excitations in 3D systems
- Duality relations among field theories in (2+1) dimensions
Conformal invariance in two dimensions and higher dimensions
- Numerical conformal bootstrap between two and four dimension
- Irreversibility of the renormalization-group flow and C-theorem in more than two dimensions
History of physics
- In 2012, together with F. Colomo, E. Castellani (Florence) and
P. Di Vecchia (Stockholm) we edited and wrote a collective book on
the early history of string theory
- We organize some colloquia on topics in between physics an philosophy
