This paper investigates the weak-coupling limit of the lattice nonlinear Schrödinger integral equation by employing matched asymptotic expansions to derive the ground-state energy and density, revealing a logarithmic divergence linked to the Bose-Einstein distribution and uncovering a resurgent transseries structure through Wiener-Hopf analysis.
This paper proposes a new covariant symplectic structure and boundary conditions at spatial infinity that extend the BMS algebra to include regular log-translations and log-supertranslations, yielding finite conserved charges with a central extension and revealing novel physical information for future observables at null and timelike infinity.
This paper establishes an exact holographic duality between 2d fermions coupled to 3d Chern-Simons gauge fields and minimal models within A-model Topological String Theory, leveraging exotic integrability to match all sphere correlation functions of meson operators.
This paper demonstrates that for a specific class of state integral models on shaped pseudo 3-manifolds, including the edge formulation of Teichmüller TQFT, the Boltzmann weight assigned to a tetrahedron satisfies the tetrahedron equation, with the tetrahedron's dihedral angles serving as spectral parameters.
This paper derives an upper bound on the anti-de Sitter radius, termed the "domain wall bound," by requiring that the tension of flux-changing domain walls exceeds the ultraviolet cutoff, thereby realizing key swampland conjectures and revealing non-trivial constraints on achieving large scale hierarchies in racetrack and KKLT-like vacua.
This paper extends the quotient quiver subtraction prescription to classical groups ( and ) using Type IIB brane constructions with planes, introducing modified graph transformations beyond simple subtraction to gauge Coulomb branch isometry subgroups and provide alternative constructions for the Higgs branches of certain higher-dimensional SCFTs.
This paper proposes a novel machine learning framework that combines gradient descent on the Grassmannian manifold with Donaldson's algorithm to efficiently compute Ricci-flat approximations of Calabi-Yau metrics, demonstrating its effectiveness and the emergence of nontrivial local minima on the Dwork family of threefolds.
This paper demonstrates that an -corrected tachyonic scalar field inflation model with a rescaled Einstein-Hilbert term can successfully achieve a phantom divide line crossing and remain compatible with ACT data, provided the effective gravitational constant during inflation is stronger than standard Einstein-Hilbert gravity.
This paper establishes that perturbative unitarity in de Sitter spacetime, analyzed via momentum-space entanglement and purity in two-scalar models, imposes an upper bound on field-space curvature of the order of the Hubble scale—a constraint arising from the spacetime's thermal nature that complements traditional flat-space bounds.
Using the effective field theory of inflationary fluctuations, this paper explicitly proves for the first time that the renormalized one-loop power spectrum of the primordial curvature perturbation freezes exactly on super-horizon scales, thereby confirming the quantum-level validity of the conservation law essential for inflationary predictions.
This paper demonstrates that within the Effective Field Theory of inflation, one-loop gravitational corrections to primordial power spectra can be fully renormalized using dimensional regularization, resulting in exactly conserved scalar and tensor spectra on super-horizon scales and proving that propagation speeds remain immune to radiative corrections from gravitational nonlinearities.
This paper proposes a scalar shortcut method that uses exact scalar field quasinormal mode deviations as an accurate proxy for gravitational corrections in beyond-Kerr scenarios, demonstrating that current ringdown constraints can be comparable to or more stringent than black hole shadow observations while offering complementary tests of gravity.
This paper investigates elastic scattering of massless scalar waves by horizonless compact objects in curved spacetime by introducing an exact Debye-series decomposition of the scattering matrix, which reveals how Regge-Debye pole spectra and branch-cut contributions govern scattering phenomena differently in neutron-star-like versus ultracompact regimes.
This paper demonstrates that single-minus tree-level -gluon scattering amplitudes, traditionally assumed to vanish, are actually non-zero for specific half-collinear or complexified momentum configurations and provides a piecewise-constant closed-form expression for these amplitudes that satisfies key consistency conditions like Weinberg's soft theorem.
This paper presents a unified exact solution to the relativistic Boltzmann equation for a boost-invariant conformal gas on across all constant-curvature slicings, which reproduces known Bjorken and Gubser flows while introducing a novel analytic "Grozdanov flow" for hyperbolic foliations that naturally encompasses both hydrodynamic and free-streaming regimes.
This paper rigorously extends the Coleman-Glaser-Martin theorem to finite temperatures, proving that the least-action saddle-point configurations for a broad class of scalar potentials are necessarily -symmetric and spatially monotonic, thereby providing a mathematical foundation for symmetry assumptions in thermal vacuum decay and cosmological phase transitions.
This paper explores the realization of spontaneous CP violation in two distinct supersymmetric scenarios—extending the spurion formalism within the exact SUSY limit and constructing a model with intermediate-scale breaking stabilized by soft SUSY breaking and non-perturbative effects—to address the strong CP problem while predicting light scalars in the CP-violating sector.
Based on recent lattice evidence and 't Hooft anomaly constraints, this paper proposes that the chiral phase transition in hot QCD for massless flavors may be described by a conformal manifold of -dependent universality classes featuring an exactly marginal operator related to baryon density, rather than a standard Ginzburg-Landau critical point.
This paper provides numerical evidence that the consistency of the 4D effective theory in Kaluza-Klein compactification requires the existence of a light scalar modulus with a mass ratio to the first KK graviton squared of at most 4/3, thereby establishing a universal limit on how rigidly the compact manifold can be stabilized.
This paper constructs Soft de Sitter Effective Theory (SdSET) using dimensional regularisation and demonstrates through explicit matching of tree-level and one-loop correlation functions that it serves as a consistent effective field theory for the quantum dynamics of superhorizon modes, successfully reproducing the infrared divergences and secular logarithms found in massless scalar field theories in de Sitter space.
