Comment on "Topography of Fermi arcs in t-PtBi2_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-PtBi2_2 and reveal that low-energy suppression persists up to 19 K, thereby resolving previous contradictions regarding surface superconductivity in this Weyl semimetal.

Sub-Thermionic Switching in a Negative-Capacitance Bandgap-Change Field-Effect Transistor

This paper proposes and models a negative-capacitance bandgap-change field-effect transistor (NC-BCFET) utilizing bilayer graphene and AlScN ferroelectric to amplify the electric field-induced bandgap opening, achieving a subthreshold swing of 15 mV/dec at room temperature—significantly surpassing the Boltzmann limit—while highlighting the potential for deep subthermionic switching in materials with larger tunable bandgaps.

Multiscale Modeling of Ion Transport in Nanopores: Fitting Implicit-Water Radial Diffusion Profiles to Explicit-Water Molecular Dynamics

This paper presents a multiscale modeling approach that fits radially varying effective diffusion coefficients from explicit-water molecular dynamics simulations into an NP+LEMC framework, successfully capturing complex ion transport behaviors and selectivity in charged nanopores that constant-diffusion models fail to reproduce.

Scalable Multiple Electron Transport Architectures for Feedback Traceable Current Sources

This paper presents a scalable, floating-gate-based Multiple Electron Transport (MET) architecture that utilizes controlled charge injection and non-destructive readout to generate stable, programmable, and electron-traceable current sources with noise reduction scaling to the square root of parallel measurements.

Enhanced thermal conductivity of (010) (AlxGa1-x)2O3 epitaxial films utilizing indium-catalyzed molecular beam epitaxy

This study demonstrates that indium-catalyzed molecular beam epitaxy enables the growth of high-quality, single-phase (010) (AlxGa1-x)2O3 films with a thermal conductivity twice that of previously reported values by suppressing defect scattering, while also characterizing the subsequent decline in thermal properties due to alloy scattering and interface stiffening.

Carrier-mediated spin helices in low-dimensional systems: Josephson-interference features and correlation renormalization

This paper theoretically investigates carrier-mediated spin helices in coupled-wire systems, demonstrating how interchannel correlations stabilize a collective quasi-two-dimensional texture and predicting that field-tunable Josephson interferometry in anisotropic superconductor-normal-metal-superconductor junctions can serve as a distinct transport probe for this spatial spin texture.

Corbino-Enhanced Supersonic Acoustic-Emission Threshold in a GaAs Two-Dimensional Electron System

This study demonstrates that a high-mobility GaAs two-dimensional electron system in a Corbino geometry exhibits a polarity-selective threshold in differential resistance at zero magnetic field, which is interpreted as a local Cherenkov-like condition for supersonic acoustic phonon emission driven by radial current concentration and modulated by Peltier heating near the inner contact.
