Free Energy Calculations: An Efficient Adaptive Biasing Potential Method [PDF]

open access: yesThe Journal of Physical Chemistry B, 2010
We develop an efficient sampling and free energy calculation technique within the adaptive biasing potential (ABP) framework. By mollifying the density of states we obtain an approximate free energy and an adaptive bias potential that is computed directly from the population along the coordinates of the free energy.

A Detailed Investigation of Gear Body-Induced Tooth Deflections and Development of an Improved Analytical Solution

open access: yesApplied Sciences, 2020
Many researchers have developed analytical methods to evaluate gear meshing stiffness. Some of these methods ignored the effect of the gear body while others used a simplified model to consider its effect. Until now, a detailed investigation of gear body-

Accurate many-body electronic structure near the basis set limit: Application to the chromium dimer [PDF]

open access: yes, 2020
We describe a method for computing near-exact energies for correlated systems with large Hilbert spaces. The method efficiently identifies the most important basis states (Slater determinants) and performs a variational calculation in the subspace ...
