Symmetries of supergravity backgrounds and supersymmetric field theory
Journal of High Energy Physics, 2020 In four spacetime dimensions, all N $$ \mathcal{N} $$ = 1 supergravity-matter systems can be formulated in the so-called U(1) superspace proposed by Howe in 1981.

Towards quantum crystallographic description of incommensurately modulated structures
Acta Crystallographica Section A, EarlyView.A modification of the structure‐factor equation for incommensurately modulated structures is proposed to enable structure description with non‐spherical atomic form factors.In this contribution, a slight modification of the structure‐factor equation for incommensurately modulated structures is proposed in order to enable structure description with non ...

Journal of High Energy Physics, 1998 The adS_{p+2} x S^{d-p-2} geometry of the near horizon branes is promoted to a supergeometry: the solution of the supergravity constraints for the vielbein, connection and form superfields are found. This supergeometry can be used for the construction of new superconformal theories.

4D N $$ \mathcal{N} $$ = 1 Kaluza-Klein superspace
Journal of High Energy Physics, 2020 Motivated by recent efforts to encode 11D supergravity in 4D N $$ \mathcal{N} $$ = 1 superfields, we introduce a general covariant framework relevant for describing any higher dimensional supergravity theory in external 4D N $$ \mathcal{N} $$ = 1 ...

From mystery to modulation: the structural story of Rb2[Si2O5]
Acta Crystallographica Section B, Volume 82, Issue 5, Page 471-480, October 2026.The crystal structure of Rb2[Si2O5] has been solved and refined as an incommensurately modulated phase. Each [SiO4] tetrahedron of the phyllosilicate adopts one of two distinct orientations, and the positions of their constituent silicon and oxygen atoms are modeled using a combination of crenel and harmonic positional modulation functions.The crystal ...

Correlation functions of spinor current multiplets in N $$ \mathcal{N} $$ = 1 superconformal theory
Journal of High Energy Physics, 2021 We consider N $$ \mathcal{N} $$ = 1 superconformal field theories in four dimensions possessing an additional conserved spinor current multiplet S α and study three-point functions involving such an operator.

Well‐posedness of heat equations with nonlinearities of arbitrarily rapid growth
Proceedings of the London Mathematical Society, Volume 133, Issue 3, September 2026.Abstract We address local‐ and global‐in‐time well‐posedness of the Cauchy problem for nonlinear heat equations without imposing growth rate restrictions on the nonlinearity a priori. Our results constitute a nontrivial expansion of the classical Lq$L^q$‐theory for nonlinearities dominated by polynomial growth and the exponential‐Orlicz space theory ...

Cohomology of Lie Superalgebras: Forms, Integral Forms and Coset Superspaces [PDF]
, 2020 We study Chevalley-Eilenberg cohomology of physically relevant Lie superalgebras related to supersymmetric theories, providing explicit expressions for their cocycles in terms of their Maurer-Cartan forms. We then include integral forms in the picture
