Facet engineering on curved Cu surfaces stabilizes metallic hexagonal blue phosphorene on (111) terraces and a new semiconducting skewed-square phosphorus phase on (513) facets, producing self-aligned metallic-semiconducting nanoarrays in one growth step.
First experimental quantum simulation of genuine non-Abelian string breaking in an SU(2) pure gauge theory on a qudit trapped-ion computer, resolving oscillations and coherent breaking driven by plaquette interactions.
A Berry-Esseen theorem is proven for local observables in quantum lattice systems with finite correlation length, yielding convergence to normality with error O(N^{-1/2} polylog N).
High-significance kSZ detections for BGS and ELG tracers reveal low gas fractions near virial radii in BGS halos likely due to AGN feedback and higher gas fractions in ELG halos suggesting weaker feedback.
Gravitational memory from hairy binary black hole mergers in scalar-Gauss-Bonnet gravity differs from GR by a few percent due to altered nonlinear dynamics, with direct scalar contributions suppressed, and including memory increases GR-sGB mismatch by more than an order of magnitude.
First PET images using polarization-correlated Compton events from entangled annihilation quanta at up to 378 MBq activity show 3.6-4.9 mm resolution, up to 20% better signal-to-background, and an estimated 10% sensitivity increase when combined with standard events.
One-parameter modular models predict exact high-scale mass relations m_s^5 = 2√2 m_d^3 m_b^2, m_μ^3 = √2 m_e m_τ^2 and m_s^2 m_τ = √2 m_e m_b^2 that become compatible with observed fermion masses after RG evolution and SUSY thresholds.
New frequency-domain models IMRPhenomXHM_NSBH, SEOBNRv5HM_ROM_NRTidalv3_NSBH, and IMRPhenomXPHM_NSBH bring higher-order modes and tidal effects to fast NSBH waveform templates.
A covariant framework is developed for photon surfaces in dynamical spherical spacetimes, recovering static limits and applied to collapse and accretion/evaporation models.
A warped-disk EMRI collision model reproduces QPE patterns in GSN 069 via a new Brightness-Recurrence Diagram and predicts possible LISA detection for a retrograde stellar-mass black hole secondary.
Quasinormal mode excitation in black hole ringdown equals the Fourier transform of the perturbation evaluated at the mode frequency, so black holes act as resonant spectral filters.
In massive scalar-tensor gravity, rotating neutron stars that collapse emit nearly the same tensor gravitational waves as in general relativity, but lose about 10^-3 solar masses of energy in scalar radiation - far more than the quadrupole channel.
A light-front Hamiltonian method evolves a quark through Glasma fields to obtain transverse momentum broadening and jet quenching consistent with classical scaling in saturation momentum.
A massless complex scalar pair coupled by a purely left-handed vector current exactly reproduces the Standard Model Michel decay spectrum; no other nonstandard invisible pair does.
Optimal success probability for identifying one or two faulty unknown unitaries is independent of total device count, achieved via an ancillary-system protocol that allows independent testing.
Axial tidal Love numbers for black holes in anisotropic fluid environments are derived analytically and numerically, with non-compact support density profiles producing logarithmic terms that obstruct standard tidal matching due to the lack of a strictly vacuum exterior.
Derives large-eccentricity asymptotics for post-Newtonian eccentric waveform Fourier modes and builds a fast endpoint-constrained analytic approximation with error under 10^{-3} valid to p=200.
Chiral symmetry corrections in lattice QCD fits shift the D0*(2300) resonance pole closer to the Dπ threshold and reduce its width, while coupled channels produce a two-pole structure.
Cycle-density filtrations based on motif densities enable persistent homology to distinguish non-isomorphic graphs nearly perfectly and achieve strong performance on real-world graph property prediction.
DESI DR2 and ACT DR6 data yield 17σ LRG-velocity, 8.3σ ELG-velocity, and 6.8σ QSO-velocity detections plus a 3.1σ velocity-velocity signal, producing f_NL^loc = 15.9_{-34.4}^{+34.6} from the velocity field.
σ-VQE uses low-depth circuits and an energy-selective cost function to preferentially prepare quantum many-body scar states on NISQ devices.
BasPhyCo is the first physical commonsense reasoning dataset for Basque and dialects, showing LLMs have limited performance on verifiability tasks especially with dialects.
