TL;DR: In this article, the authors show that material bulging against the indenter-tip is a distinctive feature in nanocontact plasticity associated with intermittent defect bursts, which is enhanced by recurrent slip traces introduced throughout the contact surface, as in the case of strongly linear defect networks in FCC Al, and by specific twin arrangements at the vicinity of BCC nanoimprints.

TL;DR: A comprehensive set of strict displacement-controlled micropillar compression experiments in conjunction with large-scale molecular dynamics and physics-based discrete dislocation dynamics simulations indicate that plastic strain bursts consist of numerous individual dislocation glide events, which span over minuscule time intervals.

TL;DR: In this article , the authors show that the quantity called "work" in the Hamiltonian derivation of the JE is neither a thermodynamic quantity nor mechanical work, except in special circumstances to be singularly assessed.

TL;DR: In this article , the effect of the bath on the measurable quantity of the Jarzynski equality was investigated through molecular dynamics simulations of crystal nanoindentation employing deterministic and stochastic thermostats.

TL;DR: In this article , the intrinsic strain associated with the coupling of twisted MoS2/MoSe2 heterobilayers was investigated by combining experiments and molecular dynamics simulations, revealing that small twist angles (between 0 and 2°) give rise to considerable atomic reconstructions, large moiré periodicities, and high levels of local strain (with an average value of ∼1%).
