All Chern-Simons invariants of 4D, N = 1 gauged superform hierarchies

Journal of High Energy Physics, 2017
We give a geometric description of supersymmetric gravity/(non-)abelian p-form hierarchies in superspaces with 4D, N = 1 super-Poincaré invariance. These hierarchies give rise to Chern-Simons-like invariants, such as those of the 5D, N = 1 graviphoton ...

Notes on super Killing tensors [PDF]

, 2016
The notion of a Killing tensor is generalised to a superspace setting. Conserved quantities associated with these are defined for superparticles and Poisson brackets are used to define a supersymmetric version of the even Schouten-Nijenhuis bracket ...

On AdS4 superspace and supergravity

Journal of High Energy Physics
In the N = 1 superspace, AdS4 supersymmetry is realized as the non-linear super coordinate transformations. The fermionic coordinates form a faithful non-linear representation of supersymmetry on their own.

All (4,0): Sigma models with (4,0) off-shell supersymmetry

Journal of High Energy Physics, 2017
Off-shell (4, 0) supermultiplets in 2-dimensions are formulated. These are used to construct sigma models whose target spaces are vector bundles over manifolds that are hyperkähler with torsion.

Temperature-pressure phase diagram of an aperiodic host guest compound [PDF]

, 2011
This letter reports on the structural instabilities of an aperiodic composite crystal under pressure. The (P, T) phase diagram up to 0.55GPa of nonadecane-urea is reported showing various symmetry breakings in crystallographic superspaces, towards three ...

Finitary Algebraic Superspace

International Journal of Theoretical Physics, 1998
An algebraic scheme is suggested in which discretized spacetime turns out to be a quantum observable. As an example, a toy model producing spacetimes of four points with different topologies is presented. The possibility of incorporating this scheme into the framework of non-commutative differential geometry is discussed.

Lorentz Covariance, Higher-Spin Superspaces and Self-Duality [PDF]

, 1998
Lorentz covariant generalisations of the notions of supersymmetry, superspace and selfduality are discussed. The essential idea is to extend standard constructions by allowing tangent vectors and coordinates which transform according to more general ...

N = 1 supercurrents of eleven-dimensional supergravity

Journal of High Energy Physics, 2018
Eleven-dimensional supergravity can be formulated in superspaces locally of the form X × Y where X is 4D N = 1 conformal superspace and Y is an arbitrary 7-manifold admitting a G 2-structure.
