Crystallography and dynamics in superspace
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.

Equivalence of superspace groups [PDF]
An algorithm is presented which determines the equivalence of two settings of a (3 + d)-dimensional superspace group (d = 1, 2, 3). The algorithm has been implemented as a web tool findssg on SSG(3+d)D, providing the transformation of any user-given superspace group to the standard setting of this superspace group in SSG(3+d)D.

Harmonic superspaces for N = (1,1), 6D SYM theory
This is a short account of the off-shell N = (1,0) and on-shell N = (1,1), 6D harmonic superspace formalism and its applications for the analysis of higher-dimension invariants in N = (1,1) SYM theory.

Superstring in doubled superspace
The covariant and kappa-symmetric action for superstring in direct product of two flat D=10 N=1 superspaces is presented. It is given by the sum of supersymmetric generalization of two copies of chiral boson actions constructed with the use of the Pasti ...

New iridium‐containing bismuth subiodides based on cuboctahedral [IrBi6I12]3− clusters adopt chain‐like or rock‐salt‐related structure variants depending on the counter‐cations. Ag3[IrBi6I12] combines silver mobility at room temperature with long‐range ordering at low temperature, while DFT calculations reveal semiconducting behavior.

Symmetries of supergravity backgrounds and supersymmetric field theory
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.

From mystery to modulation: the structural story of Rb2[Si2O5]
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 ...

4D N $$ \mathcal{N} $$ = 1 Kaluza-Klein superspace
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 ...

Well‐posedness of heat equations with nonlinearities of arbitrarily rapid growth
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 ...

AdS (super)projectors in three dimensions and partial masslessness
We derive the transverse projection operators for fields with arbitrary integer and half-integer spin on three-dimensional anti-de Sitter space, AdS3. The projectors are constructed in terms of the quadratic Casimir operators of the isometry group SO(2 ...
