We present the explicit superfield realizations of the hidden SU(4) and O(5) R-symmetries in 4D, N $$ \mathcal{N} $$ = 4 and 5D, N $$ \mathcal{N} $$ = 2 supersymmetric Yang-Mills theories in the harmonic superspace approach.

Incommensurate structure of AlPO4‐5 and its stability
The incommensurately modulated structure of AlPO4‐5 was elucidated by single‐crystal X‐ray diffraction, revealing correlated rotational displacements of AlO4 and PO4 tetrahedra.The incommensurate structure of AlPO4‐5 and its stability have been investigated in detail.

On the Ordering Mechanism of Cu+ in 2D van der Waals Multiferroic CuCrP2S6
Temperature‐dependent X‐ray single‐crystal diffuse scattering measurements of CuCrP2S6 in the (H, K, 0) plane reveal the gradual emergence and strengthening of short‐range order upon cooling from 230 to 170 K. At intermediate temperatures, diffuse features become pronounced and eventually lock into sharp incommensurate satellite reflections, indicating

Massive on-shell supersymmetric scattering amplitudes
We introduce a manifestly little group covariant on-shell superspace for massive particles in four dimensions using the massive spinor helicity formalism.

For the first time in the physics literature, the Lorentz representations of all 2,147,483,648 bosonic degrees of freedom and 2,147,483,648 fermionic degrees of freedom in an unconstrained eleven dimensional scalar superfield are presented.

Exploring oxide quasicrystals in internal space
The internal space expansion with variable system size is investigated for three different oxide quasicrystal systems. Patches of 7800, 4800 and 3600 vertices are examined in Ba–Ti–O/Pt(111), Eu–Ti–O/Pd(111) and Sr–Ti–O/Pd(111), respectively. This internal space inspection provides unique structural information for quasicrystalline systems, which goes ...

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

Splitting of supervector bundles on projective superspaces [PDF]
We provide a splitting criterion for supervector bundles over the projective superspaces $\mathbb{P}^{n|m}$. More precisely, we prove that a rank $p|q$ supervector bundle on $\mathbb{P}^{n|m}$ with vanishing intermediate cohomology is isomorphic to the ...

Non-uniqueness of the supersymmetric extension of the O(3) σ-model
We study the supersymmetric extensions of the O(3) σ-model in 1+1 and 2+1 dimensions. We show that it is possible to construct non-equivalent supersymmetric versions of a given model sharing the same bosonic sector and free from higher-derivative terms.
