The finite size effect in a two-dimensional topological insulator can induce an energy gap E g in the spectrum of helical edge states for a strip of finite width. In a recent work, it has been …
This thesis deals with quantum Monte Carlo simulations of correlated low dimensional electron systems. The correlation that we have in mind is always given by the Hubbard type …
In this thesis, we investigate aspects of the physics of heavy-fermion systems and correlated topological insulators. We numerically solve the interacting Hamiltonians that model the …
