Densities of states , moments , and maximally broken time-reversal symmetry

  author={Roger Haydock and C. M. M. Nex},
Power moments, modified moments, and optimized moments are powerful tools for solving microscopic models of macroscopic systems; however, the expansion of the density of states as a continued fraction does not converge to the macroscopic limit point-wise in energy with increasing numbers of moments. In this work the moment problem is further constrained by minimal lifetimes or maximal breaking of time-reversal symmetry, to yield approximate densities of states with pointwise macroscopic limits… CONTINUE READING
