NeuDiff Agent: a governed AI workflow for single‐crystal neutron crystallography
NeuDiff Agent accelerates the TOPAZ single‐crystal neutron diffraction workflow at the Spallation Neutron Source from measured data to a structure suitable for publication through governed tool execution, auditable provenance and checkCIF assessment.Large‐scale facilities increasingly face analysis and reporting latency as a limiting step in scientific

Exploring curved superspace [PDF]
We systematically analyze Riemannian manifolds M that admit rigid supersymmetry, focusing on four-dimensional N=1 theories with a U(1)_R symmetry. We find that M admits a single supercharge, if and only if it is a Hermitian manifold. The supercharge transforms as a scalar on M.

Temperature evolution of the high‐harmonic magnetic modulations in DyFeO3
The temperature evolution of the high‐harmonic incommensurate magnetic ordering of Dy3+ in DyFeO3 orthoferrite is compared with the literature results on the soliton lattice of TbFeO3 observed in an external magnetic field.We report on the temperature evolution of magnetic satellites associated with the incommensurate magnetic ordering of Dy3+ ions in ...

Deciphering unusually large modulations in two related organic hydroxy channel structures
Two related organic hydroxy‐channel compounds are shown to have unusually large structural modulations.The incommensurately modulated structures of two related organic hydroxy‐channel compounds [(R)‐1‐(1,3‐dihydroxypropan‐2‐yl)‐3‐(octan‐2‐yl)urea, 1; 1‐(1,3‐dihydroxypropan‐2‐yl)‐3‐octylurea, 2] have been determined and compared to the structure of a ...

Three-form multiplet and supersymmetry breaking
Recently, a nilpotent real scalar superfield V was introduced in [1] as a model for the Goldstino. It contains only two independent component fields, the Goldstino and the auxiliary D-field.

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.

Projective Superspace Varieties, Superspace Quadrics and Non-Splitting
This article is a continuation of a previous article which concerned the splitting problem for subspaces of superspaces. We begin with a general account of projective superspaces. Subsequently, we specialise to subvarieties of "positive" projective superspaces.

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.

Supersymmetric Born-Infeld actions and new Fayet-Iliopoulos terms
We consider N $$ \mathcal{N} $$ = 1 supersymmetric Born-Infeld actions that have a second non-linear supersymmetry. We focus on the model proposed by Bagger and Galperin and show that the breaking of the second supersymmetry is sourced by the new Fayet ...

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
