Bi- and uni-vector deformations of heterotic supergravity solutions are constructed using gauged double field theory together with a generalized open/closed map.
Semiclassical black hole evaporation in four dimensions produces a thunderbolt singularity signaling breakdown of the effective theory at large distances.
Asymmetric orbifold actions in Pati-Salam heterotic strings yield 24 classes with 0-12 moduli, enabling exophobic three-generation models with moduli-independent doublet-triplet splitting.
FRG in the LPA' approximation identifies the Aharony fixed point for strong dipolar magnets and yields critical exponents numerically close to but distinct from the O(3) Heisenberg class.
The one-loop graviton path integral on S² × S^{d-1} factorizes into a bulk thermal graviton gas partition function in Nariai geometry and an edge contribution from shift-symmetric fields on S^{d-1}.
The work presents a dispersive fit for the refractive index of liquid argon incorporating anomalous dispersion and proposes jet drift in simulations of heavy-ion collisions as a way to disentangle medium properties from energy loss.
CI-SM calculations supply new E1 photon strength function predictions for light nuclei that are fed into UHECR propagation simulations for a 40Ca source.
Proper-time FRG applied to gravity-coupled O(N) scalars largely reproduces scaling solutions and critical properties found with the effective average action, with some quantitative differences at finite and large N depending on improved schemes.
Edge partition functions for totally symmetric tensors in dS_{d+1} are decomposed under so(d), with the linearized gravity case receiving contributions from shift-symmetric fields on S^{d-1} suggesting an embedded brane interpretation.
Exotic differential structures on S^7 produce different Dirac operator spectra for specific symmetric gauge potentials in the Kaluza-Klein limit, implying different physical laws on topologically identical manifolds.
New 4He+4He scattering data and analysis using electron-scattering densities yields a reasonable description of the 4He resonance within existing nuclear interaction models.
A single f(Q, L_m) gravity model with HRDE produces Starobinsky-like inflation at high curvature and late-time acceleration, with RGUP corrections keeping n_s and r consistent with Planck while shifting the running of the spectral index.
Quantum teleportation using noisy top-quark pairs stays above the classical fidelity threshold of 2/3.
Lasers influence alpha decay, proton radioactivity, and nuclear excitations in isotopes such as 229Th, 83Kr, and 45Sc through methods including the time-dependent Schrödinger equation and Fermi's golden rule.
A review of hadronic parity violation covers observed effects, theoretical and experimental progress, and prospects for extending few-nucleon precision studies to nuclei and new physics searches.
Lecture notes providing a generic introduction to reheating after inflation, covering its theoretical, phenomenological, and observational aspects.
