Energy dissipation at the atomic scale explains how fracture energy depends on crack velocity in silica glass
Using molecular dynamics simulations with a machine-learned potential, this study reveals that the fracture energy of silica glass increases by up to 33% below the branching threshold due to a combination of rising intrinsic surface energy density and nanoscale roughening, demonstrating that dynamic fracture creates a fundamentally different surface structure rather than merely increasing apparent surface area.

First-principles prediction of chiral-phonon-induced orbital accumulation
Using first-principles calculations, this study demonstrates that coherent chiral lattice motion in metals induces significant orbital accumulation and a smaller spin accumulation, revealing that the response is primarily governed by orbital character and electron-phonon coupling rather than spin-orbit coupling alone, thereby identifying light transition metals as promising platforms for chiral-phonon-driven orbitronics.

Theory of transmittance of narrow quantum wires intersection in 2D systems
This paper investigates the transmittance of intersections between narrow quantum strips in 2D systems, where widths smaller than the electron wavelength allow the Schrödinger equation to be reduced to the Laplace equation and solved via conformal mappings to determine the transmittance of T-like and X-like crossings.

Nonuniform superconducting states from Majorana flat bands
This paper demonstrates that zero-energy Majorana flat bands in topological superconductors drive the spontaneous emergence of nonuniform superconducting states, specifically pair density waves and phase crystals, which lower the system's free energy by gapping out the flat band and exhibit distinct temperature-dependent stability regimes.

Remote entropy measurement in coupled quantum dots
This paper demonstrates that Maxwell relation-based charge measurements on one of two capacitively coupled GaAs quantum dots can remotely quantify the total entropy change of the entire two-dot system in response to an added electron, effectively capturing both microstate degeneracy and complex many-body correlations across varying coupling strengths.

Controlling the electro-optic response of a semiconducting perovskite coupled to a phonon-resonant cavity
This study shows that while the resonant coupling between a terahertz resonator cavity and perovskite phonons does not alter the intrinsic material properties, it significantly enhances the transient photoconductive responses of the hybrid system by up to threefold through a tunable interaction strength, thereby paving the way for frequency-controlled optical switches.

Spin waves in the bilayer van der Waals magnet CrSBr
This paper derives analytical expressions for the tunable spin wave frequencies and precession amplitudes in monolayer and antiferromagnetically coupled bilayer CrSBr across various magnetic phases, highlighting the critical roles of exchange interactions, triaxial anisotropy, and dipolar fields in governing magnetization dynamics under in-plane magnetic fields.
