Phys. Rev. B 66, 052202 (2002) [4 pages]Coulomb gap in one-dimensional disordered electron systemsReceived 18 May 2002; published 29 August 2002 The density of states of one-dimensional disordered electron systems with long-range Coulomb interaction is studied in the weak pinning limit. The density of states is found to follow a power law with an exponent determined by localization length, and this power-law behavior is consistent with the existing numerical results. © 2002 The American Physical Society URL:
