This paper provides two distinct derivations of the full nonlinear Schwarzian effective action governing the low-temperature soft mode of the large- SYK model and its chain generalization, demonstrating that these effective descriptions can be rigorously derived from microscopic dynamics without relying on additional assumptions or matching procedures.
This paper presents a scale setting and strong coupling determination for 2+1 flavor lattice QCD using HISQ ensembles, reporting precise gradient flow scales ( and ) and a potential scale () while providing a polynomial ansatz for predicting lattice spacings and estimating .
This paper formulates a WKB approach for quasiparticles with quartic dispersion, demonstrating that higher-order Airy-type functions and their hyperasymptotic corrections are essential for matching wave functions at turning points, leading to a generalized Bohr-Sommerfeld quantization condition that includes non-perturbative corrections even in the absence of tunneling.
This paper introduces new "vertical" intertwining operators that change the particle number in the quantum Calogero model for integer coupling, complementing existing "horizontal" operators to form a grid structure that enables the derivation of Liouville charges and a new basis of non-symmetric integrals through iterated intertwining.
This paper demonstrates that while staggered fermions fail to capture (2+1)D topological phases in lattice QED, Wilson fermions successfully enable the realization of diverse topological states like Chern insulators and quantum spin Hall phases, thereby resolving ambiguities in Hamiltonian formulations and providing a theoretical foundation for future quantum simulations on near-term quantum computing platforms.
This interdisciplinary paper proposes that the one-form global symmetry and its anomaly serve as a unifying organizing principle to constrain and uniquely identify the minimal topological orders underlying various fractional quantum Hall systems based on their Hall conductivity.
This paper derives a novel, local, and crossing-symmetric dispersion relation for 2-2 scattering amplitudes motivated by string theory, demonstrating its utility in bounding Wilson coefficients for gravitational effective field theories and providing convergent series representations for Veneziano, Virasoro-Shapiro, and multi-variable generalizations.
This paper proposes and rigorously establishes a symmetrization relation between 4d BPS quivers and 3d symmetric quivers, demonstrating that the wall-crossing structure of 4d Argyres-Douglas theories is isomorphic to the unlinking of their 3d counterparts and that these symmetric quivers successfully capture the Schur indices of the original 4d theories.
This paper constructs -symmetric conformal boundary states in the Wess-Zumino-Witten conformal field theory by embedding , identifies them as ground states of Affleck-Kennedy-Lieb-Tasaki spin chains within the integrable Uimin-Lai-Sutherland model, and analytically computes their boundary entropy using exact overlap formulas.
This paper establishes a central theorem that determines the necessary conditions on metric functions for the finiteness of all curvature invariants at the origin of static, spherically symmetric black holes, thereby defining the differentiability class and extendibility of such spacetimes in a model-independent, non-linear regime.
This paper extends a geometry-first formulation of the Standard Model to spontaneous symmetry breaking and Yukawa couplings, demonstrating how these mechanisms can be explained through purely geometric terms that offer a more general and transparent account of charge quantization than traditional symmetry-based approaches.
This paper investigates the backreactions of null matter loading onto the stable photon sphere in Weyl conformal gravity, revealing that the sphere's area remains invariant and that a critical loading threshold can generate an extremal horizon with AdSS geometry, a phenomenon distinct from standard nonconformal metrics.
This paper employs combinatorial methods based on the tree-level effective action to provide an explicit proof of the covariance of on-shell connected functions and derive a closed formula for tree-level scattering amplitudes with any number of external legs, without relying on specific Lagrangian formulations.
This paper investigates spatially covariant vector field theories on a flat background by performing a Hamiltonian constraint analysis to derive necessary and sufficient degeneracy conditions that eliminate the extra longitudinal degree of freedom, thereby identifying three distinct classes of theories that reduce the propagating modes from three to two, with Maxwell theory emerging as a special Lorentz-invariant case within the third class.
This paper establishes a new thermodynamic third-law analog for the repetitive electric Penrose process, demonstrating that a Reissner-Nordström black hole's charge cannot be reduced to exactly zero through a finite number of iterative steps.
This paper demonstrates that the thermal nature of Hawking radiation in gravity is the double-copy dual of charge thermality in non-abelian gauge theory, where the radiation spectrum is thermal in color charge eigenvalues rather than energy, emerging from the product of a Planck-like factor and a Wigner semicircle color phase space density.
This paper proposes a new worldsheet action for entanglement entropy in AdS/CFT that derives Einstein equations, interprets bit threads as string charge densities, and unifies the Susskind-Uglum conjecture, open-closed string duality, and ER=EPR by linking open and closed string charges to entanglement and Bekenstein-Hawking entropy respectively.
This paper investigates the stability thresholds of de Sitter and Minkowski spacetimes in holographic semiclassical gravity across dimensions , revealing that stability depends critically on the spacetime dimension and a specific dimensionless parameter , with Minkowski spacetime being universally unstable in , both spacetimes becoming unstable in beyond a critical threshold, and both remaining stable in except where higher-curvature corrections dominate.
This paper establishes universal principles and practical frameworks for simulating non-Abelian gauge theories on quantum computers by demonstrating that both gauge-singlet and non-singlet representations are valid, offering efficient circuit constructions, error analyses, and resource estimates for real-world QCD applications.
This paper develops a general canonical quantization scheme for -essence cosmology using the Dirac-Bergmann algorithm to derive a Wheeler-DeWitt equation, which is then applied to a tachyonic field model to investigate phantom crossing via quantum tunneling and the effects of boundary conditions on singularity avoidance and expansion rates.
