Isotropic polynomial invariants of Hall tensor

Abstract: The Hall tensor emerges from the study of the Hall effect, an important magnetic effect observed in electric conductors and semiconductors. The Hall tensor is third order and three dimensional, whose first two indices are skew-symmetric. In this paper, we investigate the isotropic polynomial invariants of the Hall tensor by connecting it with a second order tensor via the third order Levi-Civita tensor. We propose a minimal isotropic integrity basis with 10 invariants for the Hall tensor. Furthermore, we prove… Show more

“…In general, the skew-symmetric tensor κ ijk has nine independent components. The decomposition of this tensor has been studied recently in various publications, for example [36] and the references given therein. We examine how this decomposition follows from the decomposition of the general third-order tensor (in the contravariant version).…”

“…This year, Chen, Liu, Qi, Zheng and Zou [5] showed that eleven isotropic invariants among the Olive-Auffray minimal integrity basis of a third order symmetric tensor form an irreducible function basis of that tensor. Also in this year, a ten invariant minimal integrity basis, which is also an irreducible function basis of the Hall tensor, was presented by Liu, Ding, Qi and Zou [7]. For the piezoelectric tensor, in 2014, Olive [10] gave 495 hemitropic invariants and claimed that these hemitropic invariants form an hemitropic integrity basis.…”

“…• change the class of its elements: usually polynomial invariants are considered [33,41,25,28,13,21,23], but this is not mandatory; • look for local separating sets instead of global ones: the separating property is then defined, not on the whole vector space, but only on a neighbourhood of a given tensor. In this direction, Bona et al [8] proposed a local parametrization of orbits of generic triclinic elasticity tensors by 18 local algebraic invariants.…”
