    • Character of states near the Fermi level in (Ga,Mn)As: Impurity to valence band crossover RID E-6453-2010 
      Jungwirth, T.; Sinova, Jairo; MacDonald, A. H.; Gallagher, B. L.; Novak, V.; Edmonds, K. W.; Rushforth, A. W.; Campion, R. P.; Foxon, C. T.; Eaves, L.; Olejnik, E.; Masek, J.; Yang, S-R Eric; Wunderlich, J.; Gould, C.; Molenkamp, L. W.; Dietl, T.; Ohno, H. (American Physical Society, 2007)
      We discuss the character of states near the Fermi level in Mn-doped GaAs, as revealed by a survey of dc transport and optical studies over a wide range of Mn concentrations. A thermally activated valence-band contribution ...
    • Maximum relative excitation of a specific vibrational mode via optimum laser-pulse duration 
      Zhou, Xiang; Lin, Zhibin; Jiang, Chenwei; Gao, Meng; Allen, Roland E. (American Physical Society, 2010)
      For molecules and materials responding to femtosecond-scale optical laser pulses, we predict maximum relative excitation of a Raman-active vibrational mode with period T when the pulse has a full-width-at-halfmaximum ...
    • Response of C(60) and C(n) to ultrashort laser pulses 
      Torralva, B.; Niehaus, TA; Elstner, M.; Suhai, S.; Frauenheim, T.; Allen, Roland E. (American Physical Society, 2001)
      In this paper we introduce a method for realistic simulations of nonadiabatic processes, including the interaction of light with matter. Calculations of the response Of C(60) and carbon chains to laser pulses demonstrate ...
