Shanghai Conference on Representation Theory
... This talk is based on recent joint work with Zhang Jing. Let (W, S) be a Coxeter system and ∗ be an automorphism of W with order ≤ 2 such that s∗ ∈ S for any s ∈ S. Let I∗ be the set of twisted involutions in W . We study the reduced I∗ -expressions of twisted involutions and the braided I∗ -transfo ...

4.3 Ferromagnetism The Mean Field Approach 4.3.1 Mean Field Theory of Ferromagnetism
... In Fe, for example, we have TC = 1043 K, m = 2,2 · mBohr. It follows that HWeiss = w · J = 1.7 · 109 A/m This is a truly gigantic field strength telling us that quantum mechanical spin interactions, if existent, are not to be laughed at. If you do not have a feeling of what this number means, consid ...

Pauli`s exclusion principle in spinor coordinate space

Theoretical developments (1) support the experimentally observed effects, but the explanations have always been considered unintuitive and mathematically intricate. Quantum field theory (2; 3), argues th ...
