Research Interests (up to 2019)

Effective Field Theories of Topological Phases 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 and higher dimensions

• Numerical conformal bootstrap between two and four dimension


• Irreversibility of the renormalization-group flow 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 (see homepage)
