Incommensurate structure of AlPO4‐5 and its stability
Acta Crystallographica Section B, Volume 82, Issue 3, Page 344-351, June 2026.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.

Harmonic superspaces from superstrings
, 2004 We derive harmonic superspaces for N=2,3,4 SYM theory in four dimensions from superstring theory. The pure spinors in ten dimensions are dimensionally reduced and yield the harmonic coordinates.

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 ...

On the Ordering Mechanism of Cu+ in 2D van der Waals Multiferroic CuCrP2S6
Advanced Science, Volume 13, Issue 21, 13 April 2026.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

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.

Harmonic superspaces for N = (1,1), 6D SYM theory
EPJ Web of Conferences, 2016 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.

Exploring oxide quasicrystals in internal space
Acta Crystallographica Section A, Volume 82, Issue 2, Page 87-95, March 2026.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 ...

AdS (super)projectors in three dimensions and partial masslessness
Journal of High Energy Physics, 2021 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 ...

Fortschritte der Physik, Volume 74, Issue 1, January 2026.Abstract In this article I consider type II superstring in the pure spinor formulation with constant background fields in the context of T‐dualization. First, I prove that bosonic and fermionic T‐dualization commute using already known T‐dual transformation laws for bosonic and fermionic T‐dualization.
