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

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 ...

Circumnavigating collinear superspace
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]

Conformal (p, q) supergeometries in two dimensions
Journal 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.

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.

Exploiting superspace to clarify vacancy and Al/Si ordering in mullite
IUCrJ, 2018 Synchrotron single-crystal X-ray diffraction has revealed diffuse scattering alongside sharp satellite reflections for different samples of mullite (Al4+2xSi2−2xO10−x).

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)

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