Unified ab initio quantum-electrodynamical density-functional theory for cavity-modified electron-phonon-photon coupling in solids

This paper introduces a unified, self-consistent ab initio quantum-electrodynamical density-functional theory framework that enables the first-principles prediction of cavity-modified electronic, phononic, and optical properties in periodic solids, demonstrated through successful simulations of wurtzite GaN.

Tunable intersublattice exchange coupling drives magnetic evolution in Mn3+x_{3+x}Ga1x_{1-x}C (0x0.600 \le x \le 0.60)

This study demonstrates that substituting Mn for Ga in Mn3+x_{3+x}Ga1x_{1-x}C tunes the intersublattice exchange coupling to drive a sequential magnetic transition from antiferromagnetic to ferrimagnetic states, significantly enhancing the ordering temperature and inducing distinct transport phenomena like topological Hall resistivity.

Diffusion coefficients of multi-principal element alloys from first principles

This study introduces the embedded local cluster expansion (eLCE) method to bridge first-principles calculations with kinetic Monte Carlo simulations, enabling the prediction of diffusion coefficients in multi-principal element alloys and revealing that local kinetic barriers, rather than thermodynamics, primarily govern whether diffusion is sluggish or anti-sluggish.

Mn substitution induced a ferrimagnetic to ferromagnetic transition in trigonal Cr5Te8\text{Cr}_5\text{Te}_8

This study demonstrates that Mn substitution in trigonal Cr5Te8\text{Cr}_5\text{Te}_8 induces a transition from a ferrimagnetic to a ferromagnetic ground state, significantly enhancing both the magnetic ordering temperature and saturation moment, as confirmed by combined experimental synthesis and first-principles calculations.

Lattice-Expansion-Driven Stabilization of Helical Magnetic Order in Ru-Doped MnP

This study demonstrates that Ru doping in MnP induces a highly anisotropic lattice expansion that selectively attenuates ferromagnetic coupling to stabilize helical magnetic order, significantly elevating the ordering temperature to 215 K and establishing a universal scaling relationship between the bb-axis lattice parameter and magnetic transition temperatures.

Universal Quantum Suppression in Frustrated Ising Magnets across the Quasi-1D to 2D Crossover via Quantum Annealing

Using a D-Wave Advantage2 quantum annealer to overcome the sign problem in frustrated transverse-field Ising models, this study reveals a universal quantum suppression of ferromagnetic stability that remains constant across quasi-1D geometries before stepping down at a crossover scale to a 2D limit, thereby validating a predictive crossover law and confirming direct ferromagnet-to-paramagnet transitions.
