Transverse quantum-state characterization of programmable electron optics

This paper demonstrates the first direct measurement of the transverse quantum-state purity of a programmable electrostatic spiral phase plate using mixed-state ptychography, revealing that the device produces a substantially mixed beam rather than a pure coherent wave, a finding that enables in situ calibration and suggests significant potential improvements in dose efficiency for advanced electron imaging techniques.

Anatomy of Spin--Orbit Torques in Monolayer Fe3_3GeTe2_2 and Fe3_3GaTe2_2: Insights from atomistic and momentum-space decompositions

This first-principles study reveals that despite sharing identical crystal structures, monolayer Fe3_3GeTe2_2 and Fe3_3GaTe2_2 exhibit markedly different spin-orbit torques due to hole doping-induced changes in Fermi surface topology and spin polarization, which are elucidated through symmetry-adapted momentum-space decompositions and a phenomenological framework for self-torques.

Correlated topological-polarization surface states in the narrow-gap insulator FeSb2

This study demonstrates that epitaxial FeSb2 thin films host metallic polar surface states driven by topological polarization and strong electron correlations, evidenced by nonreciprocal transport emerging below a bulk orbital reconstruction temperature and tunable magnetic phases via electrostatic gating.

Tuning the Optoelectronics of Mixed-Semiconductors through the interplay of Quantum confinement and Stoichiometry Engineering

This study demonstrates that by decoupling ionic and electronic transport dynamics in size-tuned all-inorganic cesium lead bromide nanocrystals, the smallest nanocrystals (5.6 nm) exhibit superior charge transport and ion migration stability under strong quantum confinement when supported by tailored stoichiometry, challenging conventional beliefs about size-dependent optoelectronic performance.

ASE2SPRKKR: a unified Python framework integrating the Spin-Polarized Relativistic Korringa-Kohn-Rostoker method into the Atomic Simulation Environment

This paper introduces ASE2SPRKKR, a unified Python framework that integrates the Spin-Polarized Relativistic Korringa-Kohn-Rostoker (SPR-KKR) method into the Atomic Simulation Environment (ASE) to streamline high-throughput calculations of disordered and relativistic materials while adhering to FAIR principles for enhanced accessibility and interoperability.

Calculations of the Krypton Phase Diagram and Novel Plasticity

This paper presents a comprehensive calculation of the krypton phase diagram using the Tadah! two-body potential, revealing fcc, hcp, and bcc regions and suggesting that observed melt-curve anomalies may actually stem from bcc-fcc boundary detection by the speckle method, while also demonstrating that machine-learned potentials like MACE do not inherently outperform pair potentials if improperly trained.

Unconventional Scaling of Electric Hall Effect in Magnetic Weyl Semimetals

This paper demonstrates that two-dimensional magnetic Weyl semimetals exhibit a unique, temperature-robust Electric Hall Effect with unconventional scaling laws—ranging from a universal topological EF−1E_F^{-1} dependence at zero temperature to a logarithmically corrected divergence at finite temperatures—enabling the direct conversion of weak electric fields into measurable Hall signals.

Metal-Coordination Effects on the Stability and ORR/OER Activity of Layered Organometallic Single-Atom Catalysts: A Theoretical Study

This theoretical study demonstrates that while graphene-embedded metal-N4_4 catalysts offer competitive activity, metal-O4_4 frameworks (specifically M4_4(OHPTP)2_2 with M = Zn or Co) provide a superior balance of electrochemical stability and catalytic performance for oxygen reduction and evolution reactions across wide pH ranges.

Nonequilibrium Photocarrier and Phonon Dynamics from First Principles: a Unified Treatment of Carrier-Carrier, Carrier-Phonon, and Phonon-Phonon Scattering

This paper presents a unified first-principles many-body framework that explicitly models carrier-carrier, carrier-phonon, and phonon-phonon scattering to accurately simulate ultrafast photocarrier and phonon dynamics, including frequency renormalizations and coherent atomic motion, in semiconductors like MoS2_2 and h-BN.
