Yang-Mills Solutions and Dyons on Cylinders over Coset Spaces with Sasakian Structure
Maike Tormählen
We present solutions of the Yang-Mills equation on cylinders over coset spaces with Sasakian structure and odd dimension . The gauge potential is assume…
Star products on graded manifolds and -corrections to Courant algebroids from string theory
Andreas Deser
Deformation theory refers to an apparatus in many parts of math and physics for going from an infinitesimal (= first order) deformation to a full deformation, either formal or conv…
Sigma-model limit of Yang-Mills instantons in higher dimensions
Andreas Deser, Olaf Lechtenfeld, Alexander D. Popov
We consider the Hermitian Yang-Mills (instanton) equations for connections on vector bundles over a 2n-dimensional Kähler manifold X which is a product Y x Z of p- and q-dimensiona…
Supersymmetric Backgrounds and Generalised Special Holonomy
André Coimbra, Charles Strickland-Constable, Daniel Waldram
We define intrinsic torsion in generalised geometry and use it to introduce a new notion of generalised special holonomy. We then consider generic warped supersymmetric flux compac…
Soliton defects in one-gap periodic system and exotic supersymmetry
Adrian Arancibia, Francisco Correa, Vit Jakubsky +2
By applying Darboux-Crum transformations to the quantum one-gap Lame system, we introduce an arbitrary countable number of bound states into forbidden bands. The perturbed potentia…
Scattering matrices in the sl(3) twisted Yangian
Jean Avan, Anastasia Doikou, Nikos Karaiskos
A quantum spin chain with non-conventional boundary conditions is studied. The distinct nature of these boundary conditions arises from the conversion of a soliton to an anti-solit…
