The incommensurate composite YxOs4B4 (x = 1.161). [PDF]
Acta Crystallogr B Struct Sci Cryst Eng MaterTetragonal YxOs4B4 (x = 1.161) is an incommensurate composite of columns of Y atoms in a three‐dimensional Os4B4 framework. The structure was refined using the superspace approach.YxOs4B4 (x = 1.161) crystallizes as a tetragonal incommensurate composite of columns of Y atoms extending along [001] in an Os4B4 framework.

What is the geometry of superspace? [PDF]
Physical Review D, 1995 We investigate certain properties of the Wheeler-DeWitt metric (for constant lapse) in canonical General Relativity associated with its non-definite nature. Contribution to the conference on Mach's principle: "From Newtons Bucket to Quantum Gravity", July 26-30 1993, Tuebingen ...

Crystal tensor properties of magnetic materials with and without spin-orbit coupling. Application of spin point groups as approximate symmetries. [PDF]
Acta Crystallogr A Found AdvWe have studied the constraints that the spin group symmetry imposes on the most important crystal tensors, on the basis of a generalization of the Neumann principle to spin point groups. Some examples of real materials are presented, and their tensor forms under the spin and magnetic point groups are compared.Spin space groups, formed by operations ...

Physics Letters B, 2008 We formulate the ten-dimensional super-Yang-Mills theory in a twisted superspace with 8+1 supercharges. Its constraints do not imply the equations of motion and we solve them. As a preliminary step for a complete formulation in a twisted superspace, we give a superspace path-integral formulation of the N=2, d=4 super-Yang-Mills theory without matter ...

Journal of High Energy Physics, 2019 Abstract We classify N =1 d = 4 kinematical and aristotelian Lie superalgebras with spa- tial isotropy, but not necessarily parity nor time-reversal invariance. Employing a quater- nionic formalism which makes rotational covariance manifest and simplifies many of the calculations, we find a list of 43 isomorphism classes of Lie ...

To superspace and beyond [PDF]
Acta Crystallographica Section A Foundations and Advances, 2017 The significance of an algorithm developed by H. T. Stokes & B. J. Campbell [Acta Cryst. (2017), A73, 4-13] is discussed. The algorithm promises to be a key tool for understanding the structure-property relationships of the many technologically important materials that display incommensurate modulations in their atomic and/or magnetic structure ...

Superspaces and supersymmetries [PDF]
Communications in Mathematical Physics, 1981 A theory of graded Banach modules over a Banach-Grassmann algebra is developed and applied to differential geometry of super-manifolds. The explicit structure of superspaces carrying Poincare supersymmetry and extended supersymmetry, including central charges, is described.

Surface operators in superspace [PDF]
Journal of High Energy Physics, 2020 Abstract We generalize the geometrical formulation of Wilson loops recently introduced in [1] to the description of Wilson Surfaces. For N = (2, 0) theory in six dimensions, we provide an explicit derivation of BPS Wilson Surfaces with non-trivial coupling to scalars, together with their manifestly supersymmetric version. We derive
