Kerr-Degenerate Shadows and Distinct Strong-Deflection Lensing in Rotating Hayward-like and Bardeen-like Geometries
Chen-Hung Hsiao, Limei Yuan, Yidun Wan
We study and compare rotating Hayward-like and Bardeen-like geometries within a common Kerr-like axisymmetric ansatz, with the models distinguished by their areal-radius functions…
Anyon Condensation In Symmetry-Enriched Topological Phases: -Grading of Multifusion Categories
Nianrui Fu, Siyuan Wang, Yu Zhao +1
Although anyon condensation is a standard mechanism for relating topological orders, anyon condensation in symmetry-enriched topological (SET) phases is more intricate because the…
Non-Abelian Particle-Loop, Fracton, and Planon Condensation in Cage-Net Models
Yifei Wang, Yu Zhao, Yingcheng Li +2
We present a framework for non-Abelian p-loop, fracton, and planon condensation in 3+1 dimensions by constructing extended cage-net fracton models using decoupled layers of the Hu-…
Gravitational Lensing Signatures of Hayward-like Black Holes
Chen-Hung Hsiao, Limei Yuan, Yidun Wan
We examine the gravitational lensing signatures of a Hayward-like regular black hole and its potential observational distinction from a Schwarzschild black hole. In the weak-field…
Distinguish Bardeen-like black holes by Gravitational lensing
Limei Yuan, Chen-Hung Hsiao, Yidun Wan
We study Bardeen-like regular black holes without Cauchy horizons via gravitational lensing. In the weak field, the deflection angle receives a positive -dependent correction…
Bouncing cosmologies from Born-Infeld-type gravity
Yermek Aldabergenov, Wei Lin, Rongjian Li +2
We construct a Born-Infeld-type modification of gravity, where is the Gauss-Bonnet term, by embedding Born-Infeld electrodynamics in a five-dimensional p…
Symmetry-Enriched Topological Phases and Their Gauging: A String-Net Model Realization
Nianrui Fu, Yu Zhao, Yidun Wan
We present a systematic framework for constructing exactly-solvable lattice models of symmetry-enriched topological (SET) phases based on an enlarged version of the string-net mode…
A 2D-CFT Factory: Critical Lattice Models from Competing Anyon Condensation Processes in SymTO/SymTFT
Ling-Yan Hung, Kaixin Ji, Ce Shen +2
In this paper, we introduce a ``CFT factory'' : a novel algorithm of methodically generating 2D lattice models that would flow to 2D conformal fixed points in the infrared. These 2…
Landau-Ginzburg Paradigm of Topological Phases
Yu Zhao, Yidun Wan
Topologically ordered matter phases have been regarded as beyond the Landau-Ginzburg symmetry breaking paradigm of matter phases. Recent studies of anyon condensation in topologica…
Nonlinear Symmetry-Fragmentation of Nonabelian Anyons In Symmetry-Enriched Topological Phases: A String-Net Model Realization
Nianrui Fu, Siyuan Wang, Yu Zhao +1
Symmetry-enriched topological (SET) phases combine intrinsic topological order with global symmetries, giving rise to novel symmetry phenomena. While SET phases with Abelian anyons…
Towards Stochastic Inflation in Higher-Curvature Gravity
Yermek Aldabergenov, Ding Ding, Wei Lin +1
We study stochastic inflation in the presence of higher-curvature terms non-minimally coupled to the inflaton. Focusing on quadratic curvature invariants, we single out the Gauss-B…
Classification of Gapped Domain Walls of Topological Orders in 2+1 dimensions: A Levin-Wen Model Realization
Yanyan Chen, Siyuan Wang, Yu Zhao +2
This paper introduces a novel systematic construction of gapped domain walls (GDWs) within the Levin-Wen (LW) model. By gluing two LW models along their open sides in a compatible…
Nonabelian Anyon Condensation in 2+1d topological orders: A String-Net Model Realization
Yu Zhao, Yidun Wan
We develop a comprehensive framework for realizing anyon condensation of topological orders within the string-net model by constructing a Hamiltonian that bridges the parent string…
Noninvertible Gauge Symmetry in (2+1)d Topological Orders: A String-Net Model Realization
Yu Zhao, Yidun Wan
We develop a systematic framework for understanding symmetries in topological phases in 2+1 dimensions using the string-net model, encompassing both gauge symmetries that preserve…
Meso-inflationary Peccei-Quinn symmetry breaking with non-minimal coupling
Yermek Aldabergenov, Ding Ding, Wei Lin +1
We study a realization of the inflationary scenario where the Peccei-Quinn (PQ) symmetry is spontaneously broken during inflation, facilitated by its non-minimal coupling to gravit…
Effective dynamics of quantum fluctuations in field theory: with applications to cosmology
Ding Ding, Zhao Yu, Yidun Wan
We develop a novel framework for describing quantum fluctuations in field theory, with a focus on cosmological applications. Our method uniquely circumvents the use of operator/Hil…
