Introduction to Quantum Monte Carlo simulations for fermionic systems
Raimundo R. dos Santos
We tutorially review the determinantal Quantum Monte Carlo method for fermionic systems, using the Hubbard model as a case study. Starting with the basic ingredients of Monte Carlo…

Luttinger liquid superlattices: realization of gapless insulating phases
J. Silva-Valencia, E. Miranda, Raimundo R. dos Santos
We investigate Luttinger Liquid superlattices, a periodic structure composed of two kinds of one-dimensional systems of interacting electrons. We calculate several properties of th…

Luttinger liquid superlattices
J. Silva-Valencia, E. Miranda, Raimundo R. dos Santos
We calculate the correlation functions and the DC conductivity of Luttinger liquid superlattices, modeled by a repeated pattern of interacting and free Luttinger liquids. In a spec…
