Contribution of remote bands to orbital magnetization in twisted bilayer graphene

This paper develops a gauge-invariant Hartree-Fock framework to compute orbital magnetization in magic-angle twisted bilayer graphene, demonstrating that remote bands make substantial contributions to both orbital magnetization and self-rotation terms, necessitating careful convergence for accurate evaluation of magnetic responses in correlated moiré systems.

NMR evidence of spin supersolid and Pomeranchuk effect behaviors in the triangular-lattice antiferromagnet Rb2_2Ni2_2(SeO3_3)3_3

Through high-field 85^{85}Rb NMR measurements on the triangular-lattice antiferromagnet Rb2_2Ni2_2(SeO3_3)3_3, the study provides evidence for a magnetic up-up-down phase and two distinct gapless regimes consistent with spin supersolid phases, while revealing a unique negative slope in the UUD-V phase boundary driven by strong low-energy spin fluctuations.

Skyrmion generation via Laguerre-Gaussian beam irradiation in frustrated magnets

This paper establishes a theoretical framework for light-induced skyrmion generation in frustrated magnets by demonstrating that Laguerre-Gaussian beam irradiation nucleates skyrmions through distinct mechanisms—stochastic thermal nucleation in the ferromagnetic phase and thermal annealing in the skyrmion-lattice phase—depending on the thermodynamic region.

Quantum oscillations and linear magnetoresistance in ultraclean CaVO3_3 thin films

This study demonstrates that ultraclean, coherently strained CaVO3_3 thin films exhibit Fermi liquid behavior, quantum oscillations revealing three distinct charge carriers, and a dominant non-saturating linear magnetoresistance, highlighting the complex interplay between multiple carriers and correlations in orthorhombically distorted perovskites.

Emergent dimensional reduction in a distorted kagome magnet YCa3(CrO)3(BO3)4\mathrm{YCa_3(CrO)_3(BO_3)_4} driven by exchange hierarchy

This study demonstrates that exchange hierarchy and lattice distortion in the distorted kagome magnet YCa3(CrO)3(BO3)4\mathrm{YCa_3(CrO)_3(BO_3)_4} drive emergent dimensional reduction, reorganizing the system into weakly coupled spin chains that suppress three-dimensional magnetic order and stabilize a robust quantum-disordered state down to ultralow temperatures.

Dichotomy of electron-phonon interactions in the delafossite PdCoO2_2: From weak bulk to polaronic surface coupling

Using microscopic-area angle-resolved photoemission to overcome surface termination challenges, this study reveals a dichotomy in electron-phonon interactions within PdCoO2_2, characterized by weak coupling in the bulk and at CoO2_2-terminated surfaces, but surprisingly strong polaronic coupling at the metallic Pd-terminated surface.

Ultrafast optical excitation of magnons in 2D antiferromagnetic semiconductors via spin torque mediated by unbound electron-hole pairs and excitons: Signatures in magnonic charge pumping

This paper presents a quantum transport theory coupling nonequilibrium electron-hole dynamics with classical magnetic moment evolution to explain how femtosecond laser pulses excite magnons in 2D antiferromagnetic semiconductors via spin-transfer torque from unbound carriers and excitons, ultimately predicting that these magnons can pump detectable charge currents as a novel experimental signature.
