Rediscovering orbital mechanics with machine learning
Machine Learning: Science and Technology, 2023 We present an approach for using machine learning to automatically discover the governing equations and unknown properties (in this case, masses) of real physical systems from observations.

Ligand‐Induced Electronic Response Enables Predictive QM/MM Simulations [PDF]
Advanced SciencePredictive modeling of large molecular systems demands methods that combine quantum accuracy with scalability. Although hybrid quantum mechanics/molecular mechanics (QM/MM) simulations offer such a framework, their predictive power has been limited by ...

Mechanistic insights into the selective oxidation of D-arginine by the nonheme iron-dependent viomycin biosynthesis enzyme VioC [PDF]
iScienceSummary: VioC, a nonheme iron enzyme, catalyzes different reactions with D- and L-arginine, hydroxylating L-arginine at C3 and oxidatively deaminating D-arginine. Combining molecular dynamics with quantum mechanics/molecular mechanics (QM/MM) simulations,

Deorbiting Upper-Stages in LEO at EOM using Solar Sails [PDF]
INCAS Bulletin, 2017 This paper analyzes the possibility of deorbiting a launch vehicle upper-stage at end-of-mission from low Earth orbit through the use of a solar sail. Different solar sail sizes are taken into account.

Spin-induced orbital frustration in a hexagonal optical lattice
Physical Review Research, 2021 Complex lattices provide a versatile ground for fascinating quantum many-body physics. Here, we propose an exotic mechanics for generating orbital frustration in hexagonal lattices. We study two-component (pseudospin-1/2) Bose gases in p-orbital bands of
