   Abstract:
   We propose a multipole representation of the Fermi-Dirac function and the Fermi operator and use this representation to develop algorithms for electronic structure analysis of metallic systems. The algorithm is quite simple and efficient. Its computational cost scales logarithmically with βΔ where β is the inverse temperature and Δ is the width of the spectrum of the discretized Hamiltonian matrix. © 2009 The American Physical Society.
