Abstract

Using Monte Carlo simulations we have found a significant logarithmic size dependence for the density of defects, the shear elastic constant, and the long-range angular order in two-dimensional solids close to their melting points. These size dependencies were present for both hard discs and the repulsive inverse 12th-power potential. Our data suggest that these size dependencies may also be present at higher densities further from the melting density. Simulations very close to melting suggest that the melting densities in the literature are incorrect.

APS and the Physical Review Editorial Office Continue to Support Researchers

COVID-19 has impacted many institutions and organizations around the world, disrupting the progress of research. Through this difficult time APS and the Physical Review editorial office are fully equipped and actively working to support researchers by continuing to carry out all editorial and peer-review functions and publish research in the journals as well as minimizing disruption to journal access.

We appreciate your continued effort and commitment to helping advance science, and allowing us to publish the best physics journals in the world. And we hope you, and your loved ones, are staying safe and healthy.

Ways to Access APS Journal Articles Off-Campus

Many researchers now find themselves working away from their institutions and, thus, may have trouble accessing the Physical Review journals. To address this, we have been improving access via several different mechanisms. See Off-Campus Access to Physical Review for further instructions.
