Emergence of quasiparticles in a doped Mott insulator
Emergence of quasiparticles in a doped Mott insulator
Abstract How a Mott insulator develops into a weakly coupled metal upon doping is a central question to understanding various emergent correlated phenomena. To analyze this evolution and its connection to the high- T c cuprates, we study the single-particle spectrum for the doped Hubbard model using cluster perturbation theory …
