🔬 mesoscale physics

Comment on "Topography of Fermi arcs in t-PtBi $_2$ using high-resolution angle-resolved photoemission spectroscopy" arXiv:2503.08841 (cond-mat)

By reanalyzing the complete deposited data from O'Leary et al., this study demonstrates that their independent ARPES measurements actually confirm the existence of a strongly anisotropic superconducting gap in t-PtBi $_2$ and reveal that low-energy suppression persists up to 19 K, thereby resolving previous contradictions regarding surface superconductivity in this Weyl semimetal.

Device contacts as spin-state selectors for silicon vacancies in 4H-SiC

This study reveals that standard nickel contacts in silicon carbide devices significantly perturb the magnetic environment of silicon vacancy spins, quenching their characteristic quartet-state emission and inducing unwanted spin-doublet states, thereby highlighting the critical need for careful contact material selection to preserve quantum coherence.

Magnetic Quadrupole Lens and Current-Induced Quadrupolar Dynamics of Antiskyrmion

This paper demonstrates that antiskyrmions function as magnetic quadrupole lenses that focus or defocus electric currents, thereby inducing anisotropic current distributions and a tunable quadrupolar Hall effect that enhances antiskyrmion speed while suppressing the Hall angle to overcome key challenges for racetrack memory applications.

Perspective: The HSE Screened Hybrid and the Band Gap Problem: Origins, Impact, and the Contenders

This perspective reviews the historical origins and design philosophy of the HSE screened hybrid functional, which unexpectedly solved the band-gap problem for semiconductors, and evaluates its enduring impact alongside recent advances in semilocal and hybrid functionals against comprehensive benchmarks.

Trade-off between interface morphology and compositional homogeneity in AlGaAs/GaAs quantum wells revealed by multislice electron ptychography

Using multislice electron ptychography, this study reveals a critical trade-off in AlGaAs/GaAs asymmetric coupled quantum wells where longer growth interruptions improve interface sharpness and flatness—thereby dominating second harmonic generation responses—but simultaneously induce stronger compositional fluctuations within the AlGaAs layers.

Ultralow-Barrier Ion Transport in the Subnitride Electride Ba $_3$ N for High-Rate Sodium Storage

This study demonstrates that the subnitride electride Ba $_3$ N enables ultrafast sodium storage with low migration barriers and stable low-potential plateaus by leveraging its unique itinerant interstitial electron sea to suppress site-specific orbital interactions.

Deterministic control of antiferromagnetic domain walls by circular phonons

This paper demonstrates that deterministic control of antiferromagnetic domain walls in Ni-doped $MnPS_3$ can be achieved by using circularly polarized mid-infrared light to resonantly excite orthogonal phonon modes, thereby inducing a helicity-dependent reconfiguration of domains through a phonon-induced effective field.

Phase field modelling of microstructure transformations in Zr-Sn alloy during irradiation

This study employs a 3D phase field model integrating reaction rate theory and CALPHAD methods to investigate the spatial rearrangement of solutes and vacancies, the formation of secondary phases, and their stability under neutron irradiation in Zr-Sn alloys.

Tailoring structural, electronic, optical, and magnetic properties of rare-earth gallates RGaO $_3$ (R = Ho, Er, Tm) via first-principles investigations

This study employs first-principles DFT calculations to reveal that cubic rare-earth gallates RGaO $_3$ (R = Ho, Er, Tm) exhibit diverse electronic behaviors ranging from semiconducting to half-metallic, robust ferromagnetism, and spin-dependent optical properties that make them promising candidates for spintronic and high-energy optoelectronic applications.
