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…
To detect the looped Bloch bands of Bose-Einstein condensates in optical lattices
Dae-Il Choi, Biao Wu
A loop structure was predicted to exist in the Bloch bands of Bose-Einstein condensates in optical lattices recently in [{\it Wu and Niu, Phys. Rev. A {\bf 61}, 023402 (2000)}]. We…
Superfluidity of Bose-Einstein Condensate in An Optical Lattice: Landau-Zener Tunneling and Dynamical Instability
Biao Wu, Qian Niu
Superflow of Bose-Einstein condensate in an optical lattice is represented by a Bloch wave, a plane wave with periodic modulation of the amplitude. We review the theoretical result…
Pendulum View of The Schroedinger Equation
Biao Wu
A transformation is found between the one dimensional Schroedinger equation and a pendulum problem. It is demonstrated how to construct exact solutions with the resulted pendulum e…
Surface Phase Transitions Induced by Electron Mediated Adatom-Adatom Interaction
Junren Shi, Biao Wu, X. C. Xie +2
We propose that the indirect adatom-adatom interaction mediated by the conduction electrons of a metallic surface is responsible for the $\sqrt{3}\times \sqrt{3}\Leftrightarrow 3\t…
