Phys. Rev. B 76, 035115 (2007) [5 pages]Analytical continuation of spectral data from imaginary time axis to real frequency axis using statistical samplingReceived 27 February 2007; revised 2 May 2007; published 19 July 2007 We present a method for performing analytical continuation of spectral data from imaginary time to real frequencies based on a statistical sampling method. Compared with the maximum entropy method (MEM), an advantage is that no default model needs to be introduced. For the problems studied here, the statistical sampling method gives comparable or slightly better results than MEM using quite accurate default models. © 2007 The American Physical Society URL:
