Linear Atomic Cluster Expansion Force Fields for Organic Molecules: Beyond RMSE
Journal of Chemical Theory and Computation, 2021 We demonstrate that fast and accurate linear force fields can be built for molecules using the atomic cluster expansion (ACE) framework. The ACE models parametrize the potential energy surface in terms of body-ordered symmetric polynomials making the ...

Derivations of relativistic force transformation equations [PDF]
, 2011 The correct general form of relativistic transformation equations for the three-vector force is derived without using four-vectors, via the relativistic Newton's second law. The four-vector approach to the problem is also presented.

Observation of a correlated free four-neutron system
Nature, 2022 A long-standing question in nuclear physics is whether chargeless nuclear systems can exist. To our knowledge, only neutron stars represent near-pure neutron systems, where neutrons are squeezed together by the gravitational force to very high densities.
