Noise-canceling method computes finite-temperature elastic constants
What the study found The study shows that elastic constants, which are central material properties, can be computed at finite temperature in both thermally ordered and disordered systems using a noise-cancellation approach. Why the authors say this matters The authors say this matters because finite-temperature calculations often have poor signal-to-noise ratios, strong anharmonic effects, or…
ANATAR is a Mathematica package for multi-loop computations
What the study found ANATAR is a new Mathematica package for multi-loop computations. It integrates several existing tools for higher-order amplitude generation and analysis, and it is described as efficient, user-friendly, and flexible. Why the authors say this matters The authors say ANATAR provides a platform for higher-order computations and is optimized for computations in…
Post-training pruning makes moment tensor potentials faster
What the study found The study found that a post-training, cost-aware pruning strategy can remove expensive basis functions from Moment Tensor Potentials (MTPs) with minimal loss of accuracy. Applied to nickel and silicon-oxygen systems, the resulting models were up to seven times faster than standard MTPs. Why the authors say this matters The authors say…
