Three-dimensional Topological Insulators and Bosonization
Andrea Cappelli, Enrico Randellini, Jacopo Sisti
Massless excitations at the surface of three-dimensional time-reversal invariant topological insulators possess both fermionic and bosonic descriptions, originating from band theor…

Multipole Expansion in the Quantum Hall Effect
Andrea Cappelli, Enrico Randellini
The effective action for low-energy excitations of Laughlin's states is obtained by systematic expansion in inverse powers of the magnetic field. It is based on the W-infinity symm…
