Formulation of intrinsic nonlinear thermal conductivity for bosonic systems using quantum kinetic equation

This paper establishes a general framework for intrinsic nonlinear thermal conductivity in bosonic systems using a quantum kinetic equation approach that naturally incorporates energy magnetization, identifying quantum-geometric contributions like thermal Berry-connection polarizability (TBCP) that dominate nonlinear thermal Hall effects and differ quantitatively from semiclassical predictions.

Magnetic criticality and magnetocaloric response in MnBi2_2Te4_4 and MnBi4_4Te7_7

By combining scanning tunneling microscopy, critical scaling analysis, and magnetocaloric measurements, this study demonstrates that structural layering in MnBi2n_{2n}Te3n+1_{3n+1} compounds fundamentally governs their magnetic critical fluctuations and magnetocaloric responses, with MnBi2_2Te4_4 exhibiting robust 3D Ising-like criticality and dual-type magnetocaloric effects, while MnBi4_4Te7_7 displays crossover-dominated criticality and conventional magnetocaloric behavior due to weakened interlayer exchange.

Tuning correlated states of twisted mono-bilayer graphene with proximity-induced spin-orbit coupling

This study employs self-consistent Hartree-Fock calculations to demonstrate that proximity-induced spin-orbit coupling from a transition-metal dichalcogenide layer critically tunes the spin nature and symmetry-breaking patterns of correlated ground states in twisted mono-bilayer graphene, driving transitions between various magnetic orders and inducing chiral non-coplanar states depending on the specific type and combination of Rashba and Ising coupling.

Microscopic screening theory for excitons in two-dimensional materials: A bridge between effective models and ab initio descriptions

This paper presents a computationally efficient microscopic screening theory for excitons in two-dimensional materials that bridges the gap between effective models and first-principles methods by employing an atomistic description with quantum-screened interactions to accurately estimate binding energies and address discrepancies in existing literature.

Impact of Exchange-Correlation Functionals on Predictions of Phonon Hydrodynamics: A Study of Fluorides, Chlorides, and Hydrides

This study utilizes density functional theory with various exchange-correlation functionals to investigate the thermal and mechanical properties of alkali halides and hydrides, revealing that the choice of functional significantly influences predictions of lattice thermal conductivity and the conditions for observing phonon hydrodynamics, while also identifying new materials exhibiting this phenomenon.

Nonlocal Andreev transport through a quantum dot in a magnetic field: Interplay between Kondo, Zeeman, and Cooper-pair correlations

This paper investigates the interplay between Kondo correlations, Zeeman splitting, and Cooper-pair effects in nonlocal Andreev transport through a quantum dot coupled to normal and superconducting leads, demonstrating that crossed Andreev reflection is enhanced in the crossover region between Kondo and superconducting regimes and remains robust against magnetic fields within a specific Bogoliubov-rotation angle range.
