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…

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…
