This paper introduces a new class of interacting dark sector models where dark matter's intrinsic entropy couples to scalar field dark energy, preserving the standard expansion history while generating distinctive, scale-dependent signatures in cosmological perturbations and structure growth that remain compatible with current observations.
This paper introduces , a high-performance Go-based tool for rapidly evaluating conformal blocks in odd spacetime dimensions via recursive relations, demonstrating significant speed improvements over existing packages and successfully applying the method to optimize the mixed-correlator bootstrap of the 3D Ising model and vector models.
This paper establishes the equivalence between path integral and stochastic quantizations for generic scalar Euclidean quantum field theories by providing two novel proofs based on Taylor interpolations indexed by forests: one operating at the level of individual Feynman expansion terms and the other directly at the path integral level without requiring a full perturbative expansion.
This paper establishes a framework of Courant algebroid relations to connect Dirac structures, spinors, and generalised complex/Kähler geometries, demonstrating how these relations induce T-duality in supersymmetric sigma-models and remain compatible with Type II supergravity equations.
This paper demonstrates that within the most general formulation of gravity with independent metric and connection, a unique naturally light vector or scalar distortion field emerges as a dynamical degree of freedom, notably predicting a light scalar particle that mixes with the Higgs boson.
This paper proposes a new holographic dark energy model derived from a two-parameter generalized entropic functional, which naturally unifies standard holographic dark energy and CDM cosmology while successfully reproducing the matter-to-dark-energy transition and allowing for diverse dynamical behaviors like quintessence or phantom regimes.
This paper demonstrates that Euclidean wineglass wormholes and no-boundary instantons belong to a unified family of solutions connected by a zero-charge limit, resolving the puzzle of negative wormhole actions and revealing that while no-boundary instantons dominate the probability distribution, small-charge wormholes favor longer inflationary phases.
This paper confirms that both local operator and line defect displacement correlators in holographic thermal CFTs exhibit "bouncing singularities" linked to black hole interiors, demonstrating exact agreement between WKB and OPE analyses and proposing a factorization formula to describe deviations from this universal high-frequency structure.
This paper derives the exact dual Ginzburg-Landau theory for a minimal holographic superconductor at finite coupling, revealing that the GL parameter increases (making the system more Type-II) and the condensate rises, while correcting previous misconceptions regarding the AdS/CFT dictionary and condensate determination.
This paper investigates asymmetric renormalization group flows from higher-dimensional ultraviolet conformal field theories to lower-dimensional infrared effective theories, demonstrating how holographic charged black holes and external magnetic fields induce spatial localization that reduces the IR physics to conformal quantum mechanics or lower-dimensional CFTs.
This paper investigates the asymptotic symmetry structure of Jackiw-Teitelboim supergravity within a BF framework, demonstrating how the dilaton supermultiplet dynamically reduces the affine symmetry to a specific subalgebra with an abelian ideal, thereby providing a consistent bulk-based framework for studying boundary dynamics beyond the Schwarzian regime.
This paper formulates a ten-dimensional holomorphic supergravity on a Calabi-Yau five-fold that reproduces heterotic moduli equations, exhibits factorized anomalies reconstructing a double-extension complex for moduli counting, and is conjectured to be an -twisted version of supergravity related to the Costello-Li theory.
This paper proposes a novel mechanism for generating high-frequency gravitational waves at approximately $10^{10}$ Hz through gravitational transition radiation, where particles emit gravitons as their masses change while traversing expanding bubble walls during first-order phase transitions in the early Universe.
This paper demonstrates that higher-dimensional holographic conformal field theories exhibit ETH-monotonicity, a property reinforcing the second law of thermodynamics that becomes dominant in small black hole microstates and is linked to horizon curvature, whereas its absence in two-dimensional theories aligns with the lack of curvature singularities in BTZ black holes.
This paper demonstrates that the threshold for primordial black hole formation in a radiation-dominated universe depends not only on the compaction function but also on the spatial curvature of the core, leading to a trichotomy of initial conditions (open, closed, or flat) that significantly influence formation probabilities, mass spectra, and the potential connection to Type-II black holes and the NanoGrav signal.
Although a secondary potential barrier can induce a distinct family of spectrally unstable quasinormal modes that persist even after the barrier vanishes, time-domain simulations demonstrate that early-time black hole ringdown signals remain dominated by stable modes, thereby confirming the robustness of black hole spectroscopy.
This paper presents a new model of quantum computation based on the representation theory of the massless sector of unitary irreducible representations of the extended Poincare group.
Using Slavnov's higher covariant derivative regularization, this paper demonstrates that in a nonrenormalizable supersymmetric gauge theory with a quartic superpotential, the leading quadratically divergent correction to the gauge coupling is proportional to the correction of the matter kinetic term, establishing a relation analogous to the exact NSVZ -function.
This paper demonstrates that the chaos bound proposed in MSS can be violated in the spinor field of a Reissner-Nordström black hole by analyzing the orbital motions of both neutral and charged spinning particles, showing that sufficiently large spin magnitudes or specific spin-angular momentum alignments lead to Lyapunov exponents exceeding the surface gravity.
This paper demonstrates that the dimensional reduction of the free, massless Dirac equation on a higher-dimensional manifold with a submersion metric naturally induces CP violation in four dimensions through three distinct geometric mechanisms involving massive gauge fields, while also establishing anomaly-free gauge representations and introducing a new Lie derivative for spinors.
