The Lie algebra method with projection and Newton correction aligns vectors exactly for noiseless data and near-optimally for noisy data across classical matrix Lie groups, with formal Lean proofs.
The work constructs timelike tubes foliated by hypersurfaces with a brane-like action whose collective stress-energy is smooth, violates the strong energy condition inside the tube, and reduces to a point-particle action plus self-force term in the vanishing-radius limit.
In a thermal state of gravitons at temperature T, metric fluctuations induce a Gaussian spread in the causal structure of a scalar field with Var(x²) = 16 G_N T t³ / 3 after vacuum subtraction.
All tree-level unitarity conditions in spin-≤1 theories are captured by four- and five-point amplitudes and can be diagnosed from particle content alone.
OPE-based recursive renormalization for mixed composite operators gives five-loop anomalous dimensions in phi^4 and two-loop in phi^3 models.
Perturbative corrections to kernel ridge methods for NPIV that introduce eigenmode mixing to address ill-defined cases, with reported error reductions up to 99% when dimensionality parameter beta exceeds 0.7.
A non-Lorentzian scalar QFT with SU(1,1) symmetry obtained from N=4 SYM is finite at all orders in perturbation theory.
Form factors for B_q to J^P=2^+ tensor meson semileptonic decays are computed via light-cone QCD sum rules with external B state, yielding SM decay rates and LFU test ratios.
Exact calculations in a boost-invariant free Dirac fermion fluid show spin polarization arises only from finite spin potential, with shear-induced polarization and spin Hall effect absent.
Develops a Lagrangian path integral formulation for non-projectable Hořava gravity and computes one-loop divergences in (2+1) dimensions, verifying cancellation of linear-in-frequency terms to extract beta functions for Newton constant and λ.
Spectral functions of SYK, p-spin, and SU(M) Heisenberg models show exponential tails in spin-glass phases and quasiparticle families in spin-liquid phases, with a proof that exponential decay blocks detection of bulk causal structure.
A reweighting method creates model-agnostic likelihoods from histogram analyses, applied to Belle II B+ to K+ nu nubar data for WET constraints and light new physics searches.
Superradiant clouds around Kerr black holes amplify stochastic gravitational-wave backgrounds via stimulated emission, with rate depending on boson mass and potentially enhancing signals by orders of magnitude.
MOG produces distinct orbital precession and sky-projected deviations for S-stars that grow with the parameter α and can resemble dark matter effects while remaining testable against GR.
Real-time TDDFT simulations demonstrate that the gauge-field term in the SOC Hamiltonian governs symmetry breaking and produces dynamical spin states in systems possessing mirror, glide, or screw-rotational symmetry under external fields.
Extends LPM bremsstrahlung calculations by including masses, mapping rich behavioral regimes at high but not extreme energies.
Bose enhancement from a transient condensate of inflaton decay products dramatically increases decay efficiency and amplifies stochastic gravitational wave production to potentially observable levels.
New correlated observables from the (P_Higgs, θ_Zγ) plane with XGBoost improve H→Zγ signal discrimination from Z/γ* background, raising S/B to 2.1% (electrons) and 3.4% (muons) near the Higgs mass.
Quadratic gravity leaves the one-loop beta function of the electric charge in QED unchanged.
Derives a generic chiral anomaly formula incorporating multiple Feynman diagrams, from which abelian, singlet, consistent, and covariant forms follow, with topological discussion and FeynCalc code.
Proposes hypercomplex Yang-Mills theory as a bipartite gauge field model with doubled internal degrees of freedom via commutative ring formalism.
Machine learning models trained on known hadron data and an extended Gürsey-Radicati mass formula predict masses for triply heavy baryons and numerous pentaquark states, agreeing with available data and forecasting unobserved states.
Holographic hard-wall model produces angular distributions for high-energy pion scattering that show qualitative agreement with experimental extractions.
