Boundary lines and Askey-Wilson type moments
The Wilson line defect half-indices for 3d N=2 gauge theories with boundary confining phases admit a formulation in terms of the Askey-Wilson type moments. In the dual Landau-Ginzburg…

Discrete Approximations to U(1) Principal Bundles in Abelian Gauge Theory
A (d+1)-dimensional field theory with a periodic spatial dimension may be approximated by a d-dimensional theory with a truncated Kaluza-Klein tower of k fields; as k∞, one recovers…

Exact Infrared Triangle in Massless sQED with Long-range Interactions
The logarithmic soft photon theorem in four spacetime dimensions encodes an infinite-dimensional asymptotic symmetry which acts on massive matter as a divergent superphaserotation. Here we extend…

Brane Symmetries Revisited: Symmetries of Tensile and Tensionless Branes in Possibly Degenerate Metrics and their Manifestations
We analyse the symmetries of tensionless and tensile branes moving in a target space with a possibly degenerate metric, with the worldvolume metric remaining nondegenerate. We recover known results…

On differential operators for scalar-scaffolded gluons
Recently, based on the curve-integral formulation for stringy Trϕ3 amplitudes, a combinatorial formulation for Yang-Mills amplitudes has been proposed which describes gluons using pairs of scalars…

Subleading soft radiation during scattering of dressed states in QED
We study soft photon emission during scattering of Faddeev-Kulish charged states in QED, at leading order in perturbation theory. The charged asymptotic particles are accompanied by clouds of an…

Existence of ghost-eliminating constraints in multivielbein theory
We perform a Hamiltonian constraint analysis of the multivielbein theory proposed in [Phys. Rev. Lett. 122 (2019) 251101]. The analysis shows that the secondary constraints have the correct form to…

Reading Topological Hair from Black-Hole Entanglement
Black-hole hair can affect boundary mixed-state entanglement through local stress-energy and through topological information invisible to the classical metric. We separate these channels for a…

Recursive construction of scalar one-loop integrals in dimensional regularisation
We derive a novel recursive structure for dimensionally regularised scalar one-loop Feynman integrals based on Schläfli's differential formula for hyperbolic simplices. The recursion relates the…

Dressed States Call for Logarithmic Asymptotic Symmetries
Inspired by Wigner's classification of elementary particles as irreducible unitary representations of a spacetime symmetry group, we ask what group can give rise in this way to the quantum states…

Elastic stiffness of three-dimensional black holes and wormholes from Liouville line defects
We study elastic deformations of thin-shell black holes and wormholes in AdS3 gravity. These geometries are sourced by line defects in the dual conformal field theory, and their shape and mass…

Gravitational index of the D1-D5-P black string
We present saddle-points of the Euclidean Gravitational Path Integral (GPI) corresponding to the supersymmetric index of the D1-D5-P black string. These saddles are complex, supersymmetric,…

Localized Vector Modes on Local Cosmic Strings
We investigate the dynamics of vector excitations localized on cosmic strings in the Abelian-Higgs model. These confined gauge field fluctuations behave as massive vector degrees of freedom…

Combinatorial aspects of holographic quantum secret sharing
We introduce combinatorial holographic quantum secret sharing (CHQSS) for a bulk subregion in AdS3/CFT2 to study how logical information of the bulk subregion is encoded in the boundary and…
