The Riemann Problem for the Blood Flow Model with Body Force Term
Advances in Mathematical PhysicsIn this paper, we study the Riemann problem for the blood flow model with body force term. The Riemann solutions involve the rarefaction waves, the shock waves, and the collapsed state.

Three-body nuclear forces from a matrix model [PDF]
Journal of High Energy Physics, 2010 We compute three-body nuclear forces at short distances by using the nuclear matrix model of holographic QCD proposed in our previous paper with P. Yi. We find that the three-body forces at short distances are repulsive for (a) aligned three neutrons with averaged spins, and (b) aligned proton-proton-neutron / proton-neutron-neutron.

MBX: A many-body energy and force calculator for data-driven many-body simulations
, 2023 MBX is a C++ library that implements many-body potential energy functions (PEFs) within the “many-body energy” (MB-nrg) formalism. MB-nrg PEFs integrate an underlying polarizable model with explicit machine-learned representations of many-body ...
