Interaction Effects on Wannier Functions of a Bose-Einstein Condensate in an Optical Lattice and Implications for Bose-Hubbard Model
Z. X. Liang, B. B. Hu, Biao Wu
We show that one can properly take into account of the interaction effects and construct a set of orthonormal Wannier functions for a Bose-Einstein condensate in an optical lattice…

Direct extraction of the Eliashberg function for electron-phonon coupling: A case study of Be(1010)
Junren Shi, S. -J Tang, Biao Wu +8
We propose a systematic procedure to directly extract the Eliashberg function for electron-phonon coupling from high-resolution angle-resolved photoemission data. The procedure is…
