This paper presents a scalar-Gauss-Bonnet theory with a cubic coupling where competing curvature-induced and spin-induced scalarization mechanisms coexist, leading to a strong violation of black-hole uniqueness by admitting multiple distinct black-hole solution branches for the same mass and spin.
This paper introduces Constrained Symplectic Quantization, a holomorphic reformulation of symplectic quantization that imposes constraints on intrinsic time Hamiltonian flow to resolve structural limitations and establish exact equivalence with the Feynman path integral, thereby enabling the accurate numerical sampling of real-time quantum observables as demonstrated on the quantum harmonic oscillator.
This paper constructs a renormalization-group improved Schwarzschild black hole geometry using exact Scheme B running, demonstrating that quantum corrections regularize the central singularity, induce nontrivial thermodynamic phase structures with stable remnants, and shift critical points while preserving the global topological number of the solution.
These Master level course notes provide an introduction to holography and the AdS/CFT correspondence, systematically covering foundational symmetries, Anti-de Sitter geometry, the holographic dictionary, black hole thermodynamics, and the emergence of gravity from entanglement.
This paper proposes Discrete θ Projection, a gauge-protected, axionless solution to the Strong CP problem that dynamically enforces a small physical QCD angle by gauging a finite cyclic subgroup of the theta shift symmetry, ensuring radiative and gravitational stability without introducing new light particles.
This paper demonstrates that TeV-scale heavy neutral leptons in an inverse-seesaw model can simultaneously generate neutrino masses and produce light pseudo-Nambu-Goldstone boson dark matter via freeze-in, establishing a predictive link between neutrino mass generation, dark matter abundance, and decay signatures testable at future colliders and neutrino detectors.
This paper realizes homological blocks of knot complements as half-indices of 3d theories via inverted Habiro series, demonstrating that specific integration contours capture abelian flat connections while alternative pole selections yield colored Jones polynomials.
This paper derives a canonical quantisation-based Worldline Quantum Field Theory formalism suitable for both scattering and bound configurations of the classical two-body problem, utilizing the Magnus expansion to compute matrix elements that encode physical observables.
This paper presents a combined analytical and numerical study of field theory cosmic strings, demonstrating that while translational Goldstone modes lack nontrivial curvature corrections, massive shape modes couple to worldsheet curvature to induce parametric instabilities that transfer energy between sectors.
Motivated by gauge-string duality and quantum information, this paper defines layered degeneracy graphs to construct monomial bases for finite-dimensional commutative associative semisimple algebras, proving counting consistency and conjecturing determinant formulas that ensure invertibility for applications in symmetric group algebras and multi-matrix invariants.
Using an analogue gravity model on a spacetime with a naked singularity, the authors derive exact electromagnetic solutions that remain regular and demonstrate the possibility of transmitting power flux across the singularity.
This paper presents updated lattice results on the intrinsic width of the flux tube in (2+1)-dimensional SU(2) Yang-Mills theory, demonstrating a constant value at low temperatures consistent with the Clem model and a growing trend near the deconfinement transition that aligns with Svetitsky-Yaffe mapping predictions.
This paper explores the implications of dynamical open string degrees of freedom in 7D half-maximal gauged supergravity derived from massive type IIA compactifications, leading to the discovery of new supersymmetric and non-supersymmetric AdS7 vacua and the construction of interpolating domain wall solutions to investigate their stability.
This paper presents compact analytic expressions for tree-level 2 → 2 scattering amplitudes in agravity coupled to QED, systematically including photon-graviton interference contributions and demonstrating characteristic ultra-Planckian scaling and infrared enhancements.
This paper investigates the confinement/deconfinement transition in pure Yang-Mills theories using the Curci-Ferrari model, demonstrating that predicted transition temperatures are robust against variations in renormalization scale and scheme, and align closely with lattice simulation results, thereby validating the model's effectiveness as an infrared description.
This paper employs the Lanczos algorithm to investigate Krylov complexity in the early universe as an open system across inflation, radiation, and matter domination epochs, revealing distinct dissipative behaviors, the similarity of complexity evolution across various inflationary potentials, and deriving new evolution equations for squeezing parameters via Meixner polynomials to demonstrate rapid decoherence-like effects.
This paper proposes an observable that distinguishes between quark and hadron phases in a finite-temperature quark-gluon plasma by linking the energy cost of static quark probes (via Polyakov loops) to the medium's capacity to screen them through meson or baryon formation.
This paper proves that the fast mode dynamics in quantum operator evolution exhibit emergent random matrix universality within the Krylov space recursion method, leading to universal Green's function scaling forms in both chaotic and non-chaotic systems and enabling a new spectral bootstrap technique for approximating spectral functions.
This paper proposes a novel mechanism called Magnetically Arrested Transmutation (MAT), wherein strong magnetic fields in compact stars halt the accretion of endoparasitic black holes formed by dark matter, thereby explaining the over-representation of magnetic white dwarfs and the unique presence of magnetars near the Galactic center.
This paper introduces the Optical Time Algorithm (OTA), a flexible framework that utilizes a single, reconfigurable optical circuit to efficiently simulate diverse free quantum field dynamics—including varying coupling geometries, spacetime metrics, and boundary conditions—thereby overcoming the rigidity of traditional experimental setups and paving the way for tabletop investigations of quantum field theories.
