Abstract 3D symmetric tensor fields have a wide range of applications in medicine, science, and engineering. The topology can provide key insight into their structures. In this paper we study the number possible topological bifurcations linear fields. Using linearity/planarity classification wedge/trisector classification, explore four types that change connectivity degenerate curves as well lo...

Numerically solving a second quantised many-body model in the permutation symmetric Fock space can be challenging for two reasons: (i) an increased complication calculations of matrix elements various operators, and (ii) poor scaling cost these with size. We present method that solves both problems. find mapping used to simplify elements. The is directly generated so its computational scales on...
