Laser-written reconfigurable energy landscapes and programmable Moiré spin textures

This paper presents a focused laser-assisted local field cooling technique that enables non-destructive, nanoscale reprogramming of exchange-bias anisotropy to engineer tunable magnetic energy landscapes, thereby facilitating the creation of reconfigurable artificial spin metamaterials and programmable Moiré spin textures for advanced spintronic applications.

Obstructed Cooper pairs in flat band systems - weakly-coherent superfluids and exact spin liquids

This paper demonstrates that in line-graph lattices with strong attractive interactions, doped charges form obstructed Cooper pairs whose motion is frustrated by destructive interference, causing the pair kinetic energy to vanish and resulting in a disorder-free, interaction-driven localization that yields an exact spin liquid ground state with topological order.

Iron spin crossover in ferropericlase and its effect on lower-mantle thermal conductivity

This study presents the first direct measurements of ferropericlase thermal conductivity under lower-mantle conditions, revealing a significant reduction linked to the iron spin crossover that helps define a comprehensive lower-mantle conductivity profile and constrain geodynamic evolution.

Configuration-dependent electronic and optical properties of 2D Mo1x_{1-x}Wx_xS2_2 alloys across the full composition range

This study reveals that while the structural stability of 2D Mo1x_{1-x}Wx_xS2_2 alloys is primarily composition-driven, their electronic and optical properties, including band-edge splitting, valley energetics, and optical selection rules, are critically governed by the specific microscopic arrangement of atoms across the full composition range.
