  • Shvetsov-Shilovski, N.I.; Lein, Manfred; Madsen, L.B.; Räsänen, E.; Lemell, C.; Burgdörfer, J.; Arbó, D.G.; Tokési, K. (College Park, MD : American Physical Society, 2016)
    We present a semiclassical two-step model for strong-field ionization that accounts for path interferences of tunnel-ionized electrons in the ionic potential beyond perturbation theory. Within the framework of a classical ...
  • Horiuchi, S.; Shirakawa, T.; Ohta, Y. (Bristol : IOP Publishing Ltd., 2009)
    Electronic states of hollandite vanadate K2V8O 16, a one-dimensional zigzag-chain system of t2g orbitals in a mixed valent state, are considered. We calculate the Madelung energies to determine the most stable charge-ordering ...
