Multi-shifted BiCG spectral simulation paper published in Phys. Rev. B

Our paper about the multi-shifted biconjugate gradient method has been published in Phys. Rev. B! Congrats to Prakash and Luogen. This work solves a long-standing problem for the simulation of resonant spectroscopies. It accelerates these Kramers-Heisenberg-type spectra to the level comparable to linear spectra.
