WebMay 16, 2024 · Therefore, the 2 × 1 column vectors the 2 × 2 matrices of the representation work on must code rotations. This coding actually means that the sum of two 2 x 1 column vectors will not code a rotation, so he concludes that the spinors do not form a vector space, but itself the spin group manifold SU (2) (or SL (2, C) for Lorenzian spinors). WebJan 15, 2013 · The lifetime of magnons in a spin-1 {sup 87}Rb spinor condensate is shown to be much longer than that of phonons due to the difference in their dispersion relations.

In quantum field theory, the Dirac spinor is the spinor that describes all known fundamental particles that are fermions, with the possible exception of neutrinos. It appears in the plane-wave solution to the Dirac equation, and is a certain combination of two Weyl spinors, specifically, a bispinor that transforms "spinorially" under the action of the Lorentz group. Dirac spinors are important and interesting in numerous ways. Foremost, they are important as t… Web工作经历：. 2015年-2024年华威大学（英国）博士后研究员. 2024年-2024年伍珀塔尔大学&杜塞尔多夫大学（德国）博士后研究员. 2024年-至今中山大学（广州）副教授. dancing beauty worm
