This study reveals a sublattice dichotomy in the tunneling spectra of high-quality monolayer FeSe grown on SrTiO, where distinct coherence peak asymmetries between Fe sublattices are attributed to an unconventional -pairing mechanism between and states.
This study combines inelastic neutron scattering experiments and DFT-based theoretical modeling to reveal that the spin dynamics in BaKFeAs exhibit a distinct three-dimensional character with out-of-plane modulations at low energies that evolve into a two-dimensional profile at higher energies, a phenomenon accurately captured by a realistic 3D electronic band structure that highlights the crucial role of states away from the Fermi level over simple Fermi surface nesting.
This report presents collaborative recommendations from a diverse group of experts to improve reproducibility and replicability in condensed matter physics by outlining best practices and policies across all stages of the scientific process.
This paper reports the achievement of record-high critical current densities in Nb/PdNi/Nb Josephson junctions, demonstrating that the PdNi barrier's perpendicular magnetic anisotropy enables zero-field operation and establishing it as a promising material for superconducting digital logic and qubit applications.
This paper introduces a bias-assisted laser-based ARPES technique that applies a sample voltage to expand the accessible momentum range and achieve full 2 solid angle collection while preserving high energy and angular resolution.
This study investigates the pairing symmetry of superconducting BaPtAsSb, revealing that while the Sb-rich end () exhibits a time-reversal symmetry-breaking chiral -wave state, the As-rich end () favors competitive nodal -wave or conventional -wave states without such symmetry breaking.
This paper introduces soliton_solver, an open-source, GPU-accelerated Python package that utilizes a modular, theory-agnostic architecture to efficiently simulate and visualize topological solitons across diverse two-dimensional non-linear field theories.
This study demonstrates that oxygen diffusion from lithography resist during the lift-off fabrication of Niobium nanowires causes the superconducting transition width to broaden as wire width decreases, while confirming that these devices behave as two-dimensional superconductors suitable for high-temperature hybrid quantum applications.
This paper investigates the phase diagrams of both conventional Landau and fractionalized theories of intertwined orders under periodic driving, utilizing the large- limit and Markovian bath coupling to reveal diverse long-time dynamical behaviors ranging from stable averages and period-doubling oscillations to quasi-periodicity and chaos.
This paper presents a numerical model of SNSPD absorption that incorporates quantum-corrected optical conductivity of niobium nitride films, demonstrating that the detector's wavelength range is significantly influenced by the material's optical properties rather than solely by its geometric cavity parameters.
