Density Matrix Renormalization Group and Quantum Information applied to Quantum Critical Phenomena in One-Dimensional Systems
We investigate three different types of quantum phase transition occurring in quasi one-dimensional systems theoretically and numerically. First, we study the band-insulator to Mott-insulator transition occurring in charge-transfer complexes, for which the half-filled one-dimensional ionic Hubbard...
