Description:
Author(s): Andreas Holzner, Andreas Weichselbaum, Ian P. McCulloch, Ulrich Schollwöck, and Jan von Delft We show that recursively generated Chebyshev expansions offer numerically efficient representations for calculating zero-temperature spectral functions of one-dimensional lattice models using matrix product state (MPS) methods. The main features of this Chebyshev matrix product state (CheMPS) approa... [Phys. Rev. B 83, 195115] Published Tue May 10, 2011
