Description:
Author(s): Gergő Roósz, Uma Divakaran, Heiko Rieger, and Ferenc Iglói We consider the one-dimensional XX model in a quasiperiodic transverse field described by the Harper potential, which is equivalent to a tight-binding model of spinless fermions with a quasiperiodic chemical potential. For weak transverse field (chemical potential), h〈hc, the excitations (fermion... [Phys. Rev. B 90, 184202] Published Fri Nov 07, 2014
