A study of nonlocal conductivity in high-temperature superconductors
S. J. Phillipson, M. A. Moore, T. Blum
We examine nonlocal conductivity in high-temperature superconductors from a phenomenological point of view. One wants to deduce the properties of the conductivity, especially its i…
Variational Schemes in the Fokker-Planck Equation
T. Blum, A. J. McKane
We investigate variational methods for finding approximate solutions to the Fokker-Planck equation, especially in cases lacking detailed balance. These schemes fall into two classe…
Improved Perturbation Theory for the Kardar-Parisi-Zhang Equation
T. Blum, A. J. McKane
We apply a number of schemes which variationally improve perturbation theory for the Kardar-Parisi-Zhang equation in order to extract estimates for the dynamic exponent z. The resu…
Glassy Solutions of the Kardar-Pasrisi-Zhang Equation
M. A. Moore, T. Blum J. P. Doherty, M. Marsili +2
It is shown that the mode-coupling equations for the strong-coupling limit of the KPZ equation have a solution for d>4 such that the dynamic exponent z is 2 (with possible logarith…
