On phase separation and crystallization of Ge-rich GeSbTe alloys from atomistic simulations with a machine learning interatomic potential

This paper presents a highly transferable machine learning interatomic potential for Ge-rich GeSbTe alloys, which was used to simulate nanosecond-scale crystallization at 600 K, revealing that kinetic effects during memory set operations lead to metastable phase separation into Sb-doped cubic GeTe and amorphous GeSb/Ge rather than thermodynamically stable products.

Giant Room-Temperature Third-Order Electrical Transport in a Thin-Film Altermagnet Candidate

This study demonstrates that (101)-oriented RuO₂ thin films, a candidate altermagnet, exhibit giant room-temperature third-order electrical transport responses driven by simultaneous T-odd and T-even quantum geometric quantities, providing a robust method to detect Néel order and a versatile platform for quantum spintronic devices.

Twistoptics in Planar Heterostructures with an Arbitrary Number of Rotated 3D Thin Layers and 2D Conductive Sheets

This paper presents a general analytical framework and open-source numerical tools to model light propagation and polariton behavior in planar heterostructures composed of an arbitrary number of rotated 3D anisotropic layers and 2D conductive sheets, thereby establishing a foundational theory for twist-engineered nano-optics.

Magnetic Microscopy of Skyrmions in Magnetic Thin Films with Chiral Overlayers

This study utilizes wide-field nitrogen-vacancy magnetometry to demonstrate that chiral molecular overlayers induce enantioselective and magnetic-field-dependent modifications to the size, spacing, and shape of skyrmions in CoFeB thin films, revealing a pathway for molecular control of topological spin textures via magneto-chiral coupling.

Symmetry-protected coexistence of a nodal surface and multiple types of Weyl fermions in P63P6_3-B30\text{B}_{30}

This paper proposes the structurally stable boron allotrope P63P6_3-B30\text{B}_{30} as a pristine spinless topological semimetal that uniquely hosts a symmetry-protected two-dimensional nodal surface alongside multiple types of Weyl fermions, offering an ideal platform to study the interplay of multidimensional topological states.

Twist-engineering of a robust Quantum Spin Hall phase in β\beta-/flat bismuthene bilayer from first principles

This first-principles study demonstrates that twisting a β\beta-bismuthene monolayer by 30∘^\circ onto a planar bismuthene layer on a SiC substrate induces unique orbital hybridization and Rashba spin-splitting, resulting in a robust and tunable Quantum Spin Hall phase with enhanced topological responses.

Nanoporous High Entropy Alloys: Overcoming Brittleness Through Strain Hardening

This study demonstrates that incorporating high entropy alloys into bicontinuous nanoporous structures overcomes inherent macroscopic brittleness through strain hardening mechanisms like dislocation starvation and sluggish motion, resulting in materials with specific strengths 5 to 10 times higher than single-element counterparts and enhanced thermal resilience.
