Covariant differential calculi on quantum symplectic superspace S P q 1 | 2

, 2017
A unitary orthosymplectic quantum supergroup is introduced. Two covariant differential calculi on the quantum superspace SPq1|2 are presented. The h-deformed symplectic superspaces via a contraction of the q-deformed symplectic superspaces are obtained ...

Temperature-pressure phase diagram of an aperiodic host guest compound

, 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 ...

Radiation field on superspace [PDF]

, 1995
We study the dynamics of multiwormhole configurations within the framework of the Euclidean Polyakov approach to string theory, incorporating a modification to the Hamiltonian which leads to a Planckian probability measure for the Coleman parameters $α$ that allows $\frac{1}{2}α^{2}$ to be interpreted as the energy of the quanta of a radiation field on

The dark side of double-tensor multiplets

Journal of High Energy Physics
We explore the properties of a set of free double-tensor multiplets in N $$ \mathcal{N} $$ = 2 supersymmetry, focusing on their behavior within rigid superspace.

Lorentz Covariance, Higher-Spin Superspaces and Self-Duality

, 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 ...

The anti-de Sitter supergeometry revisited

Journal of High Energy Physics
In a supergravity framework, the N $$ \mathcal{N} $$ -extended anti-de Sitter (AdS) superspace in four spacetime dimensions, AdS 4 4 N $$ {\textrm{AdS}}^{4\left|4\mathcal{N}\right.} $$ , is a maximally symmetric background that is described by a curved ...

DAMTP 2009–52 A Connection between Twistors and Superstring Sigma Models on Coset Superspaces

, 2009
We consider superstring sigma models that are based on coset superspaces G/H in which H arises as the fixed point set of an order-4 automorphism of G. We show by means of twistor theory that the corresponding first-order system, consisting of the Maurer ...
