Field-selective criticality in 2D melting revealed by multi-field Lee-Yang zeros

By applying Lee-Yang zeros to study bilayer water under nanoconfinement, this paper reveals that 2D melting exhibits field-selective criticality where the solid-hexatic and hexatic-liquid transitions respond differently to temperature and lateral pressure, thereby resolving long-standing contradictions between simulations, models, and experiments by identifying which thermodynamic channel each probe observes.

Percolation of a rod-like particle in a static bed of spheres: trapping and passing

This study numerically demonstrates that the percolation of rod-like particles through a static bed of spheres is governed by a transition between trapping and passing regimes determined by rod length and pore geometry, where shorter rods move nearly twice as fast as longer ones due to reduced susceptibility to geometric trapping.
