This paper investigates the relationship between non-local magic and entanglement in quantum many-body systems, establishing bounds on classical simulation hardness and conjecturing a linear scaling in conformal field theories, while proving that in holographic duals, non-local magic vanishes precisely when gravitational back-reaction is absent and is approximately equal to the rate of change of minimal surface area with respect to cosmic brane tension.
This paper proposes that the patterns of spontaneous symmetry breaking and vacuum degeneracy in scalar and gauge field systems can be qualitatively classified by modeling the vacuum manifold as a principal groupoid bundle and analyzing the singular foliation it induces on the moduli space of vacuum expectation values.
This paper extends Nielsen's Theorem on LOCC ordering to bipartite quantum systems described by commuting von Neumann algebras, establishing a one-to-one correspondence between the classification of factors (types I, II, and III) and their operational entanglement properties, such as infinite single-shot entanglement and the ability to transition between arbitrary pure states with arbitrary precision.
This paper investigates the quantum transition between Schwarzschild and string black holes in the large limit by reducing the problem to two dimensions via T-duality, deriving the Wheeler-De Witt equation to treat the geometries as distinct wave function states, and calculating the transition probability driven by string coupling.
This paper numerically computes the energy-momentum tensor of baryons in top-down holographic QCD, revealing a D-term value of approximately -2.05 that is significantly larger in magnitude than previous findings.
This paper compares top-down and bottom-up holographic constructions of conformal defects and boundaries in AdS/CFT by analyzing bulk point singularities in correlation functions, demonstrating that D3/D5 boundary CFTs can only be modeled by specific tension configurations of end-of-the-world branes and providing a calculation of the central charge for M2/M5 boundary CFTs.
This paper proposes a method to derive the Bekenstein-Hawking entropy of extremal black holes by calculating the entanglement entropy of disconnected one-dimensional conformal quantum mechanics systems, thereby demonstrating that horizon entropy fundamentally originates from quantum entanglement.
This paper demonstrates that the two-dimensional long-range Ising model with a line defect fails to factorize in the infrared limit, a phenomenon attributed to the model's equivalence to a higher-dimensional local conformal field theory where the extra dimension maintains connectivity across the defect.
This paper identifies exact magnetic monopole solutions in spontaneously broken gauge theories within the BPS limit that possess a new internal degree of freedom, which modulates the monopole's energy density profile while preserving its total mass.
This paper investigates the resurgent structure of the topological string dual to 2d Yang-Mills theory on a torus by deriving closed-form formulas for instanton amplitudes to propose a real non-perturbative partition function and identifying two infinite towers of complex instantons corresponding to BPS states in type II string theory.
This paper proposes a novel quasi-topological gravity model that unifies cosmological and black hole scenarios by replacing spacetime singularities with a "big bounce" and a "black bounce," respectively, thereby reproducing key results from loop quantum cosmology and the quantum Oppenheimer-Snyder model within a single, manifestly covariant framework.
This paper derives a fundamental, model-independent inequality that limits the detectability of vacuum excitations in finite-size local detectors based on a trade-off between vacuum insensitivity and excitation sensitivity, offering a potential experimental test for the axioms of algebraic quantum field theory.
This paper systematically analyzes the vacuum stability of a specific 331 model with three triplets and a softly broken symmetry by identifying all potential minima, deriving conditions for a global electroweak vacuum, and calculating metastability bounds to map the viable parameter space in terms of physical quantities.
This paper investigates the causal structure and interior geometry of asymptotically AdS black holes containing vacuum bubbles by analyzing holographic entanglement entropy and bulk-cone singularities, revealing that while collapsing and expanding bubbles exhibit thermalization, static bubbles display non-thermal "scar state" properties.
This paper proposes a minimal framework utilizing the discrete gauge symmetry , motivated by the Standard Model's internal structure, to naturally resolve the axion quality problem while simultaneously explaining neutrino masses, baryon asymmetry, and dark matter.
This paper generalizes Carrollian Lie algebroids to the framework of -commutative (almost commutative) geometry via -Lie-Rinehart pairs, establishing foundational analogues for Carrollian structures and demonstrating their application through explicit constructions on the extended quantum plane and the noncommutative 2-torus.
This paper demonstrates that incorporating quantum fluctuations via Jackiw-Teitelboim (JT) gravity in a holographic model of near-extremal black branes generates a non-universal, temperature-dependent shear viscosity to entropy ratio () that dips below the KSS bound in the semi-classical regime before rising above it at lower temperatures, a result that aligns with the quantum-corrected absorption cross-section.
This paper proposes constructing local gauge invariant operators on isometry-breaking backgrounds via the Stückelberg mechanism—effectively introducing physical clocks and rods—but argues that suppressing the resulting spacetime fluctuations to reliably define operators in localized regions (such as black hole islands) requires strong isometry breaking, potentially achieved through transitions to higher-dimensional black holes.
This paper demonstrates that Newtonian gravity can generate quantum entanglement between mesoscopic bodies only when the gravitational tidal field is quantized (as in the mini-superspace framework), whereas models treating the field as classical (semiclassical and stochastic gravity) fail to produce such entanglement.
This paper presents a simplified Standard Model plus gravity framework featuring left and right mirror sectors that share and gravitational fields to cancel anomalies, interprets the right sector as dark matter, and explores the cosmological and quantum implications of Weyl symmetry, including potential solutions to the cosmological constant problem and the avoidance of negative norm states.
