Accurate estimation of interfacial thermal conductance between silicon and diamond enabled by a machine learning interatomic potential

This study demonstrates that machine learning interatomic potentials trained on density functional theory data significantly improve the accuracy of interfacial thermal conductance predictions between silicon and diamond compared to traditional semi-empirical potentials, while also providing detailed insights into phonon mode contributions and bonding characteristics.

3D Magnetic Textures with Mixed Topology: Unlocking the Tunable Hopf Index

This paper introduces a discrete geometric definition of the Hopf index for periodic magnetic textures, demonstrating that fractional and non-integer values naturally arise as "mixed topology" states resulting from the interplay between self-linking and inter-linking of flux tubes.

Spin-orbit interactions, time-reversal symmetry, and spin selection

This paper reviews various mechanisms, such as magnetic fields, time-dependent fields, and multi-terminal configurations, that overcome the fundamental time-reversal symmetry constraints to enable spin-selective transport in noninteracting electron systems, while also exploring potential connections to the chiral-induced spin selectivity phenomenon.

Ultrafast dynamics of atomic correlated disordering in photoinduced VO $_2$

Using real-time time-dependent density functional theory, this study reveals that photoinduced phase transitions in VO $_2$ are driven by anisotropic "correlated disorder" where V-V dimers undergo elongation and constrained rotation, a process that becomes temperature-independent above a critical excitation threshold due to thermally excited phonons randomizing lattice vibrations.

Current-induced spin-orbit torque on the surface of a transition metal dichalcogenide connected to a two-dimensional ferromagnet CrI $_3$ : Effects of twisting and gating

This study employs the steady-state Boltzmann equation to demonstrate that current-induced spin-orbit torque in TMDC/CrI $_3$ bilayers can be significantly enhanced, reversed, and tuned by up to an order of magnitude through the strategic manipulation of doping type, twist angle, and transverse gate electric fields.

Robust Interlayer Exciton Interplay in Twisted van der Waals Heterotrilayer on a Broadband Bragg Reflector up to Room Temperature

This study demonstrates that integrating a precisely stacked MoSe $_{2}$ / $^{1}$ WSe $_{2}$ / $^{2}$ WSe $_{2}$ heterotrilayer onto a chirped distributed Bragg reflector creates a robust platform for enhanced, long-lived interlayer excitons with distinct valley-polarized dynamics that remain stable from cryogenic temperatures up to room temperature.

Shape of Wigner Crystals and Hole Self-Doping in a Mexican-Hat Dispersion

This study utilizes variational Monte Carlo calculations to demonstrate that Wigner crystals formed from a Mexican-hat dispersion can be energetically stabilized near the phase transition by optimizing orbital shapes to deplete electrons at $k=0$ and incorporating hole self-doping with electron-vacancy correlations.

Ion Flow under an Applied Electric Field in Semiconducting and Metallic Carbon Nanotubes

This paper explores the theoretical origins of the conflicting experimental findings regarding potassium ion flow rates in metallic versus semiconducting carbon nanotubes, where one study found similar rates in subnanometer tubes while another observed higher conductivity in semiconducting tubes of larger diameters.
