      Silkin, Viatcheslav M.; Balassis, A.; Echenique Landiribar, Pedro Miguel; Tchoulkov Savkin, Evgueni Vladimirovich (American Physical Society, 2009-08)
      We present ab initio time-dependent density-functional theory calculation results for low-energy collective electron excitations in MgB2. The existence of a long-lived collective excitation corresponding to coherent charge ...
