Particle models from special Jordan backgrounds and spectral triples
Fabien Besnard, Shane Farnsworth
We put forward a definition for spectral triples and algebraic backgrounds based on Jordan coordinate algebras. We also propose natural and gauge-invariant bosonic configuration sp…
Incompatibility of Frequency Splitting and Spatial Localization: A Quantitative Analysis of Hegerfeldt's Theorem
Felix Finster, Claudio F. Paganini
We prove quantitative versions of the following statement: If a solution of the 1+1-dimensional wave equation has spatially compact support and consists mainly of positive frequenc…
Causal Fermion Systems and the ETH Approach to Quantum Theory
Felix Finster, Jürg Fröhlich, Marco Oppio +1
After reviewing the theory of "causal fermion systems" (CFS theory) and the "Events, Trees, and Histories Approach" to quantum theory (ETH approach), we compare some of the mathema…
Gauge Symmetries and Renormalization
David Prinz
We study the perturbative renormalization of quantum gauge theories in the Hopf algebra setup of Connes and Kreimer. It was shown by van Suijlekom (2007) that the quantum counterpa…
The Zilch Electromagnetic Conservation Law Revisited
Sajad Aghapour, Lars Andersson, Kjell Rosquist
It is shown that the zilch conservation law arises as the Noether current corresponding to a variational symmetry of a duality-symmetric Maxwell Lagrangian. The action of the corre…
On deformations of -algebras
Alexey A. Sharapov, Evgeny D. Skvortsov
A simple method is proposed for deforming -algebras by means of the resolution technique. The method is then applied to the associative algebras of polynomial functions o…
Pentagon identities arising in supersymmetric gauge theory computations
Deniz N. Bozkurt, Ilmar Gahramanov
The partition functions of three-dimensional N=2 supersymmetric gauge theories on different manifolds can be expressed as q-hypergeometric integrals. By comparing the partition fun…
A simple construction of associative deformations
Alexey A. Sharapov, Evgeny D. Skvortsov
We propose a simple approach to formal deformations of associative algebras. It exploits the machinery of multiplicative coresolutions of an associative algebra A in the category o…
Integrable lattice spin models from supersymmetric dualities
Ilmar Gahramanov, Shahriyar Jafarzade
Recently, there has been observed an interesting correspondence between supersymmetric quiver gauge theories with four supercharges and integrable lattice models of statistical mec…
The star-triangle relation, lens partition function, and hypergeometric sum/integrals
Ilmar Gahramanov, Andrew P. Kels
The aim of the present paper is to consider the hyperbolic limit of an elliptic hypergeometric sum/integral identity, and associated lattice model of statistical mechanics previous…
Near integrability of kink lattice with higher order interactions
Yunguo Jiang, Jiazhen Liu, Song He
In the paper, we make use of Manton's analytical method to investigate the force between kink and the anti-kink with large distance in dimensional field theory. The related p…
The graded product of real spectral triples
Shane Farnsworth
Forming the product of two geometric spaces is one of the most basic operations in geometry, but in the spectral-triple formulation of non-commutative geometry, the standard prescr…
Spherically symmetric potential in noncommutative spacetime with a compactified extra dimensions
Sêcloka Lazare Guedezounme, Antonin Danvidé Kanfon, Dine Ousmane Samary
The Schrödinger equation of the spherical symmetry quantum models such as the hydrogen atom problem seems to be analytically non-solvable in higher dimensions. When we try to compa…
High Energy Scattering in Higher Dimensional Theories
Jnanadeva Maharana
The high energy behavior of scattering amplitudes in spacetime dimensions, , is investigated. The bound on total cross sections, , has…
Bethe Ansatz for Yangian Invariants: Towards Super Yang-Mills Scattering Amplitudes
Rouven Frassek, Nils Kanning, Yumi Ko +1
We propose that Baxter's Z-invariant six-vertex model at the rational gl(2) point on a planar but in general not rectangular lattice provides a way to study Yangian invariants. The…
Coherent states, 6j symbols and properties of the next to leading order asymptotic expansions
Wojciech Kaminski, Sebastian Steinhaus
We present the first complete derivation of the well-known asymptotic expansion of the SU(2) 6j symbol using a coherent state approach, in particular we succeed in computing the de…
Melons are branched polymers
Razvan Gurau, James P. Ryan
Melonic graphs constitute the family of graphs arising at leading order in the 1/N expansion of tensor models. They were shown to lead to a continuum phase, reminiscent of branched…
Quantization maps, algebra representation and non-commutative Fourier transform for Lie groups
Carlos Guedes, Daniele Oriti, Matti Raasakka
The phase space given by the cotangent bundle of a Lie group appears in the context of several models for physical systems. A representation for the quantum system in terms of non-…
Solutions of the Klein-Gordon equation in an infinite square-well potential with a moving wall
Michael Koehn
Employing a transformation to hyperbolic space, we derive in a simple way exact solutions for the Klein-Gordon equation in an infinite square-well potential with one boundary movin…
The Tetrahedron Zamolodchikov Algebra and the AdS5 x S5 S-matrix
Vladimir Mitev, Matthias Staudacher, Zengo Tsuboi
The S-matrix of the string theory is a tensor product of two centrally extended su(2|2) S-matrices, each of which is related to the R-matrix of the Hubbard model…
A note on the principle of least action and Dirac matrices
Maciej Trzetrzelewski
Many Lagrangians of physical theories can be expressed as eigenvalues of certain, relatively simple, matrices involving Dirac gamma matrices. We give concrete examples for Lagrangi…
Matrix regularization of embedded 4-manifolds
Maciej Trzetrzelewski
We consider products of two 2-manifolds such as S^2 x S^2, embedded in Euclidean space and show that the corresponding 4-volume preserving diffeomorphism algebra can be approximate…
T-duality of current algebras and their quantization
Pedram Hekmati, Varghese Mathai
In this paper we show that the T-duality transform of Bouwknegt, Evslin and Mathai applies to determine isomorphisms of certain current algebras and their associated vertex algebra…
Momentum transforms and Laplacians in fractional spaces
Gianluca Calcagni, Giuseppe Nardelli
We define an infinite class of unitary transformations between position and momentum fractional spaces, thus generalizing the Fourier transform to a special class of fractal geomet…
