Plasticity as a depinning phase transition
… work we study plasticity as a pinning-depinning phase transition employing a discrete dislocation dynamics (DDD) model and a phase eld crystal (PFC) model in two dimensions. Below a critical ( ow) stress, the dislocations are pinned/jammed within their glide plane due to long-range elastic …

Phase transition behaviour in constraint satisfaction problems
… research has shown that the CSP exhibits a phase transition as a control parameter is varied. This transition lies between a region where most problems are easy and soluble, and a region where most problems are easy but insoluble. In the intervening phase transition region, the average …

Phase transition induced deformation in porous media
… are the most familiar examples of first-order phase transitions in equilibrium thermodynamics. Porous, amorphous materials are widely used in everyday life, yet their complex spatial structures lead to unresolved questions for statistical mechanics, both in- and out-of equilibrium. In this …

The electroweak phase transition in models with gauge singlets
A strong first order phase transition is needed for generating the baryon asymmetry; and also to save it during the electroweak phase transition (EWPT). However this condition is not fulfilled within the Standard Model (SM), but in its extensions. It is widely believed that the existence of singlet …
