    • Landau-Zener transitions in a linear chain 
      Pokrovsky, Valery L.; Sinitsyn, NA. (American Physical Society, 2002)
      We present an exact asymptotic solution for electron transition amplitudes in an infinite linear chain driven by an external time-dependent electric field. This solution extends the Landau-Zener theory for the case of an ...
    • Vacuum energy and repulsive Casimir forces in quantum star graphs 
      Fulling, Stephen; Kaplan, L.; Wilson, J. H. (American Physical Society, 2007)
      Casimir pistons are models in which finite Casimir forces can be calculated without any suspect renormalizations. It has been suggested that such forces are always attractive, but we present several counterexamples, notably ...
