Poisson gauge models and Seiberg-Witten map
Journal of High Energy Physics, 2022 The semiclassical limit of full non-commutative gauge theory is known as Poisson gauge theory. In this work we revise the construction of Poisson gauge theory paying attention to the geometric meaning of the structures involved and advance in the ...

Symmetries of parabolic geometries
Differential Geometry and its Applications, 2009 We generalize the concept of affine locally symmetric spaces for parabolic geometries. We discuss mainly $|1|$--graded geometries and we show some restrictions on their curvature coming from the existence of symmetries. We use the theory of Weyl structures to discuss more interesting $|1|$--graded geometries which can carry a symmetry in a point with ...

Geometry-symmetry-free and material-symmetry-guaranteed polariton-induced transparency
iScienceSummary: Plasmon-induced transparency is a classical analogue of electromagnetically induced transparency (EIT). However, its realization and control primarily rely on geometry engineering rather than tuning plasmon polaritons (PPs) themselves, due to ...

Geometric Curvatures of Plane Symmetry Black Hole
Advances in High Energy Physics, 2013 We study the properties and thermodynamic stability of the plane symmetry black hole from the viewpoint of geometry. We find that the Weinhold curvature gives the first-order phase transition at N=1, where N is a parameter of the plane symmetry black ...

Symmetry as tactics of solving mathematical problems
Lietuvos Matematikos Rinkinys, 2012 The article explores symmetry as tactics in solving various mathematical problems. Although in Mathematics curriculum while learning about Geometry, symmetry is taught and simple straightforward exercises are solved, it is argued that the application of ...

A novel approach to non-commutative gauge theory
Journal of High Energy Physics, 2020 We propose a field theoretical model defined on non-commutative space-time with non-constant non-commutativity parameter Θ(x), which satisfies two main requirements: it is gauge invariant and reproduces in the commutative limit, Θ → 0, the standard U(1 ...

Pressure-induced symmetry changes in body-centred cubic zeolites [PDF]
Royal Society Open Science, 2019 Previous work has shown a strong correlation between zeolite framework flexibility and the nature of structural symmetry and phase transitions. However, there is little experimental data regarding this relationship, in addition to how flexibility can be ...

Bis(1-adamantylammonium) tetrachloridocobaltate(II)
Acta Crystallographica Section E, 2008 The CoII atom in the title salt, (C10H18N)2[CoCl4], exists in a tetrahedral coordination geometry. The asymmetric unit has two cations that lie on different special positions of site symmetry m; the anion lies on another special position of site symmetry

Internal symmetry in Poincarè gauge gravity
Nuclear Physics BWe find a large internal symmetry within 4-dimensional Poincarè gauge theory.In the Riemann-Cartan geometry of Poincaré gauge theory the field equation and geodesics are invariant under projective transformation, just as in affine geometry.
