Quadratic Diffusion Monte-Carlo Algorithms for Solving Atomic Many-Body Problems
(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 ...
Response of C(60) and C(n) to ultrashort laser pulses
(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 ...
