New NHMC method improves Boltzmann sampling accuracy

Researchers have developed a novel method called Neural Non-Equilibrium Hamiltonian Monte Carlo (NHMC) for more accurate sampling from Boltzmann densities. This approach trains a sampler to generate stochastic Hamiltonian-style paths, which are then statistically corrected using recorded non-equilibrium work. NHMC has shown promise in estimating normalizing constants and free-energy differences on various test cases, including molecular internal-coordinate studies, though its effectiveness is dependent on sufficient path overlap.
