Conformal Superspace: the configuration space of general relativity [PDF]
arXiv, 2010 It has long been considered that conformal superspace is the natural configuration space for canonical general relativity. However, this was never definitively demonstrated. We have found that the standard conformal method of solving the Einstein constraints has an unexpected extra symmetry. This allows us to complete the project.

Hexagonal and Trigonal Quasiperiodic Tilings
Israel Journal of Chemistry, Volume 64, Issue 10-11, November 2024.Abstract Exploring nonminimal‐rank quasicrystals, which have symmetries that can be found in both periodic and aperiodic crystals, often provides new insight into the physical nature of aperiodic long‐range order in models that are easier to treat. Motivated by the prevalence of experimental systems exhibiting aperiodic long‐range order with hexagonal ...

The three-dimensional N $$ \mathcal{N} $$ = 2 superfishnet theory
Journal of High Energy PhysicsWe propose a double-scaling limit of β-deformed ABJM theory in three-dimensional N $$ \mathcal{N} $$ = 2 superspace, and a non-local deformation thereof.

Superfield Realizations of Lorentz Violation
, 2003 Lorentz-violating extensions of the Wess-Zumino model have been formulated in superspace. The models respect a supersymmetry algebra and can be understood as arising from suitably modified superspace transformations.Comment: 7 ...

Canonical‐Cell Tilings and their Atomic Decorations
Israel Journal of Chemistry, Volume 64, Issue 10-11, November 2024.Abstract The canonical cell tiling is a geometrical framework that uses four kinds of basic polyhedra, called the canonical cells, to model the packing of atoms and clusters in icosahedral quasicrystals and related periodic approximants. Over the past three decades, it has become increasingly clear that this framework is the most sensible approach to ...

Error estimates for completely discrete FEM in energy‐type and weaker norms
Numerical Methods for Partial Differential Equations, Volume 40, Issue 6, November 2024.Abstract The paper presents error estimates within a unified abstract framework for the analysis of FEM for boundary value problems with linear diffusion‐convection‐reaction equations and boundary conditions of mixed type. Since neither conformity nor consistency properties are assumed, the method is called completely discrete.

Supersymmetric action for multiple D0-brane system
Journal of High Energy Physics, 2018 We have constructed a complete action for the system of N D0-branes in flat 10D type IIA superspace. It is invariant under the rigid spacetime supersymmetry and local worldline supersymmetry (κ-symmetry). This latter can be considered as supersymmetry of

Painleve Analysis in Superspace [PDF]
arXiv, 2000 A method for carrying out the Painleve test in superspace is proposed. The method is then applied to the one-parameter N=1 supersymmetric extensions of the KdV equation.

Realizations of Thermal Supersymmetry
, 1998 We investigate realizations of supersymmetry at finite temperature in terms of thermal superfields, in a thermally constrained superspace: the Grassmann coordinates are promoted to be time-dependent and antiperiodic, with a period given by the inverse ...

The N=2 superconformal gravitino multiplet
Physics Letters B, 2023 We propose a new gauge prepotential ϒi describing the four-dimensional N=2 superconformal gravitino multiplet. The former naturally arises via a superspace reduction of the N=3 conformal supergravity multiplet.
