Generalization of Nambu–Hamilton Equation and Extension of Nambu–Poisson Bracket to Superspace [PDF]
Universe, 2018 We propose a generalization of the Nambu–Hamilton equation in superspace R 3 | 2 with three real and two Grassmann coordinates. We construct the even degree vector field in the superspace R 3 | 2 by means of the right-hand sides

Orthorhombic charge density wave on the tetragonal lattice of EuAl4 [PDF]
IUCrJ, 2022 EuAl4 possesses the BaAl4 crystal structure type with tetragonal symmetry I4/mmm. It undergoes a charge density wave (CDW) transition at TCDW = 145 K and features four consecutive antiferromagnetic phase transitions below 16 K. Here we use single-crystal

Circumnavigating collinear superspace [PDF]
Journal of High Energy Physics, 2020 In this paper, we extend the collinear superspace formalism to include the full range of N $$ \mathcal{N} $$ = 1 supersymmetric interactions. Building on the effective field theory rules developed in a companion paper — Navigating Collinear Superspace [1]

Towards massive field-theory amplitudes from the cohomology of pure spinor superspace [PDF]
Journal of High Energy PhysicsBy analogy with the formula for the massless string disk amplitudes, we define massive field-theory tree amplitudes and conjecture that the BRST cohomology structure of pure spinor superspace fixes their form. We give evidence by deriving the pure spinor

Dunkl-Poisson Equation and Related Equations in Superspace
Mathematical Modelling and Analysis, 2015 In this paper, we investigate the Almansi expansion for solutions of Dunkl-polyharmonic equations by the 0-normalized system for the Dunkl-Laplace operator in superspace.

Quantum Cosmology with Third Quantisation
Universe, 2021 We reviewed the canonical quantisation of the geometry of the spacetime in the cases of a simply and a non-simply connected manifold. In the former, we analysed the information contained in the solutions of the Wheeler–DeWitt equation and showed their ...

Superfield approach to interacting N = 2 massive and massless supermultiplets in 3d flat space
Journal of High Energy Physics, 2021 Massive arbitrary spin supermultiplets and massless (scalar and spin one-half) supermultiplets of the N = 2 Poincaré superalgebra in three-dimensional flat space are considered. Both the integer spin and half-integer spin supermultiplets are studied. For

Five-dimensional supergravity in N = 1/2 superspace
Journal of High Energy Physics, 2020 We construct 5D, N = 1 supergravity in a 4D, N = 1 superspace with an extra bosonic coordinate. This represents four of the supersymmetries and the associated Poincaré symmetries manifestly. The remaining four supersymmetries and the rest of the Poincaré

(0, 4) Projective superspaces. Part I. Interacting linear sigma models
Journal of High Energy Physics, 2023 We describe the projective superspace approach to supersymmetric models with off-shell (0, 4) supersymmetry in two dimensions. In addition to the usual superspace coordinates, projective superspace has extra bosonic variables — one doublet for each SU(2)

Non-Projected Supermanifolds and Embeddings in Super Grassmannians
Universe, 2018 In this paper we give a brief account of the relations between non-projected supermanifolds and projectivity in supergeometry. Following the general results (L.
