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.

On AdS4 superspace and supergravity
Journal of High Energy PhysicsIn 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.

Klein and conformal superspaces, split algebras and spinor orbits
, 2017 We discuss [Formula: see text] Klein and Klein-conformal superspaces in [Formula: see text] space-time dimensions, realizing them in terms of their functor of points over the split composition algebra [Formula: see text]. We exploit the observation that

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 ...

Phase transitions within crystals that are aperiodic by construction
, 2022 International audienceAperiodic crystals possess long-range order without translational symmetry. They constitute a state of matter that has forced a profound paradigm shift in solid-state physics.

, 1996 A large class of supersymmetric extended objects is considered from the viewpoint of embeddings of super worldsurfaces into target superspaces. It is shown that a simple geometrical condition leads to the equations of motion for the brane in many ...

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 ...

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 ...

Admissible Systems and Graded Hermitian Superspaces
We introduce the notion of admissible systems for involutions on complex contragredient Lie superalgebras, and classify the involutions with admissible systems by circlings on extended Dynkin diagrams.
