Superfield approach to interacting N = 2 massive and massless supermultiplets in 3d flat space

open access: yesJournal 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

Conformal (p, q) supergeometries in two dimensions

open access: yesJournal of High Energy Physics, 2023
We propose a superspace formulation for conformal (p, q) supergravity in two dimensions as a gauge theory of the superconformal group OSp0(p|2; ℝ) × OSp0(q|2; ℝ) with a flat connection.

Crystallography and dynamics in superspace [PDF]

open access: yesEPJ Web of Conferences, 2017
The discovery in materials of long range order without lattice periodicity has generated a very broad field of research with the introduction of totally new concepts. The common feature of this new state of matter is the translational symmetry recovered by adding supplementary dimensions to the physical space, defining a crystallographic superspace ...

Five-dimensional supergravity in N = 1/2 superspace

open access: yesJournal 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

open access: yesJournal 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)

Orthorhombic charge density wave on the tetragonal lattice of EuAl4

open access: yesIUCrJ, 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

Exploiting superspace to clarify vacancy and Al/Si ordering in mullite

open access: yesIUCrJ, 2018
Synchrotron single-crystal X-ray diffraction has revealed diffuse scattering alongside sharp satellite reflections for different samples of mullite (Al4+2xSi2−2xO10−x).

Non-Projected Supermanifolds and Embeddings in Super Grassmannians

open access: yesUniverse, 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.

Junctions of mass-deformed nonlinear sigma models on SO(2N)/U(N) and Sp(N)/U(N). Part II

open access: yesJournal of High Energy Physics, 2020
We construct three-pronged junctions of mass-deformed nonlinear sigma models on SO(2N)/U(N) and Sp(N )/U(N ) for generic N. We study the nonlinear sigma models on the Grassmann manifold or on the complex projective space.

Generalization of Nambu–Hamilton Equation and Extension of Nambu–Poisson Bracket to Superspace

open access: yesUniverse, 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
