Gradient Symplectic Algorithms for Solving the Schroedinger Equation with Time-Dependent Potentials
S. A. Chin, C. R. Chen
We show that the method of factorizing the evolution operator to fourth order with purely positive coefficients, in conjunction with Suzuki's method of implementing time-ordering o…
Fourth Order Diffusion Monte Carlo Algorithms for Solving Quantum Many-Body Problems
Harald A. Forbert, Siu A. Chin
By decomposing the important sampled imaginary time Schrödinger evolution operator to fourth order with positive coefficients, we derived a number of distinct fourth order Diffusio…
Fourth Order Algorithms for Solving the Multivariable Langevin Equation and the Kramers Equation
Harald A. Forbert, Siu A. Chin
We develop a fourth order simulation algorithm for solving the stochastic Langevin equation. The method consists of identifying solvable operators in the Fokker-Planck equation, fa…
Fermionic and Bosonic Bubbles and Foam
Aurel Bulgac, Siu A. Chin, Harald A. Forbert +2
The positioning of one or more bubbles inside a many fermion or boson system, does not affect the volume, surface or curvature terms in the liquid drop expansion of the total energ…
