Structural transitions related to order-disorder and thermal desorption of D atoms in TbFe2_{2}D4.2_{4.2}

This study elucidates the structural evolution of TbFe2_{2}D4.2_{4.2} deuteride through temperature-dependent order-disorder transitions and thermal desorption, revealing a reversible shift from a monoclinic to a cubic structure and identifying various intermediate phases with cubic, monoclinic, and tetragonal superstructures that reconcile previous conflicting reports on hydride crystallography.

Environmental Breakdown of Topological Interface States in Armchair Graphene Nanoribbon Heterostructures

This paper theoretically demonstrates that the stability of topological interface states in armchair graphene nanoribbon heterostructures embedded in boron nitride sheets critically depends on the surrounding topology, where symmetric BN environments destroy these states through chirality breaking while reverse-topology environments preserve them and enhance interdot hopping.

A unified variational framework for phase-field fracture and third-medium contact in finite deformation hyperelasticity

This paper introduces a unified variational framework that integrates phase-field fracture and third-medium contact within finite deformation hyperelasticity by regularizing both crack topology and contact interfaces, thereby eliminating the need for explicit tracking algorithms while successfully simulating complex coupled phenomena like secondary crushing in Brazilian disk tests.

Mechanical Control of Polar Order

This study demonstrates that applying mechanical pressure to epitaxial BiFeO3 thin films suppresses ferroelastic domain competition and significantly lowers the energy barrier for polarization reversal, enabling spontaneous switching at zero voltage and establishing mechanical stress as a powerful thermodynamic control parameter for manipulating multiferroic order.
