The authors derive new multisoliton solutions in Anti-de Sitter and single solitons in de Sitter spacetimes using a curvature-deformed sine-Gordon model.
Families of complex tensor trace-invariants with tree-like dominant pairings factorize at large N, allowing computation of typical multipartite Rényi entropies for uniform random states.
Complete asymptotic freedom holds in these chiral theories with scalars for particular choices of gauge group size and multiplicities of vector-like and chiral fermion families.
Pairs of large-N 1D CFTs encode generalized free fields on a timelike geodesic in de Sitter space via large-N factorization, 1D conformal symmetry, and split representations of dS Green functions.
Transformers reconstruct the constituent RCFTs in tensor-product theories from low-energy spectra, reaching 98% accuracy on WZW models and generalizing to larger central charges with few out-of-domain examples.
Transformer networks sample up to 180x180 2D Ising systems and 64x64 Edwards-Anderson systems by generating spin groups with probability approximations, yielding ~20x higher effective sample size than prior neural samplers at criticality.
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.
Non-perturbative heavy quark diffusion coefficients in arbitrarily magnetized QGP become anisotropic due to magnetic field restrictions on longitudinal gluon spectral function, with non-perturbative effects dominant at low temperatures.
DeepOPiraKAN learns parameter-to-spectrum mappings via operator learning and achieves relative errors of O(10^{-6}) to O(10^{-4}) for Kerr black hole quasinormal modes up to n=7 when benchmarked against Leaver's method.
Dr.Sai autonomously executed full physics analysis pipelines on real BESIII data to re-measure ten J/psi decay branching fractions, matching established benchmarks without any manual coding.
Generalized BPS magnetic monopoles exist in inhomogeneous Yang-Mills-Higgs models with spatially varying couplings constrained to preserve the BPS bound, yielding exact solutions when the permeability exponent is 1 and a spectrum of compact, hollow, and multi-shell configurations otherwise.
A fibre-bundle model with dual spacetimes (smooth manifold plus causal set) derives relative locality in general PQG theories without requiring momentum-space curvature.
Robinson-Trautman waves exhibit an explicit memory effect, with their news-free sector matching boosted rescaled Schwarzschild black holes and the vacuum sector of Euclidean Liouville theory.
Scalarized Kerr-Newman black holes develop an inner photon shell that produces an additional critical curve and distinct crescent-like higher-order images unlike those in Kerr spacetime.
Relativistic continuous matrix product states yield competitive variational approximations to ground state energies and observables in the phi^4, Sine-Gordon, and Sinh-Gordon models, including strongly coupled regimes.
Reformulating local polynomial fitting with orthogonal Chebyshev polynomials yields two algorithms that cut memory use, improve scalability, and deliver orders-of-magnitude better numerical accuracy than Vandermonde-based methods for Savitzky-Golay filters.
MeVPrtl is a new event generator that implements Higgs portal, heavy neutral lepton, and heavy QCD axion models for use in short-baseline neutrino experiments.
Fast driving across first-order transitions in relativistic scalar fields produces temperature- and dimension-independent finite-time scaling matching mean-field theory, crossing over to Kibble-Zurek scaling near criticality and nucleation-dominated dynamics at low temperatures.
In 1+1D QCD the baryon Bethe-Salpeter equation reduces to the Bars-Durgut equation under valence truncation and is solved numerically for the spectrum and parton distributions.
Rotational averages of the angular correlation function isolate non-statistical isotropy components in the CMB sky as a real-space complement to BipoSH coefficients.
A centimeter-scale dynamic optical cavity with heterodyne readout achieves sub-femtometer per square root Hertz displacement sensitivity above 8 Hz and tracks motions over ten orders of magnitude in range.
Leptophilic ALPs with m_a > f_a can explain the electron anomalous magnetic moment tension over a large parameter space and are testable via μ→e conversion.
Extended misalignment for axion-like particles with constant-ω_ϕ pre-oscillation and dark radiation coupling yields data-driven constraints favoring negative ω_ϕ and f_ϕ in [80, 1.5×10^10] TeV but does not ease cosmological tensions.
