(American Physical Society, 2008)A simple formula is obtained for coupling electrons in a complex system to the electromagnetic field. It includes the effect of intra-atomic excitations and nuclear motion, and can be applied in, e.g., first-principles-based ...
-
(American Physical Society, 2011)Using large-scale Monte Carlo simulations that combine parallel tempering with specialized cluster updates, we show that Ising spin glasses with Levy-distributed interactions share the same universality class as Ising spin ...

(American Physical Society, 1991)Using Hellmann-Feynman molecular-dynamics simulations, we have investigated interactions of first-row elements with the (110) surfaces of GaAs and InP. We find that these atoms prefer to occupy subsurface sites. The open ...

(American Physical Society, 2010)We study a p-spin spin-glass model to understand if the finite-temperature glass transition found in the mean-field regime of p-spin models, and used to model the behavior of structural glasses, persists in the nonmean-field ...
-
(American Physical Society, 1990)The diffusion Monte Carlo algorithm with and without importance sampling is analyzed in terms of the algorithm's underlying transfer matrix. The crucial role played by the Langevin algorithm in the importance-sampling ...

(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 ...
