Pauli group

In physics and mathematics, the Pauli group on 1 qubit is the 16-element matrix group consisting of the 2 × 2 identity matrix and all of the Pauli matrices , together with the products of these matrices with the factors and : . The Pauli group is generated by the Pauli matrices, and like them it is named after Wolfgang Pauli. The Pauli group on qubits, , is the group generated by the operators described above applied to each of qubits in the tensor product Hilbert space . As an abstract group, is the central product of a cyclic group of order 4 and the dihedral group of order 8. The Pauli group is a representation of the gamma group in three-dimensional Euclidean space. It is not isomorphic to the gamma group; it is less free, in that its chiral element is whereas there is no such relationship for the gamma group. (Wikipedia).

Richard Kerner - Geometry, Matter and Physics

We show how the fundamental statistical properties of quantum fields combined with the superposition principle lead to continuous symmetries including the $SL(2,\mathbb C)$ group and the internal symmetry groups $SU(2)$ and $SU(3)$. The exact colour symmetry is related to ternary $\mathbb

Was Brian Cox wrong? - Sixty Symbols

Brian Cox ruffled a few feathers with a TV lecture which touched upon the Pauli Exclusion Principle. Two of our Sixty Symbols regulars - Ed Copeland and Tony Padilla - try to explain what it was all about. Here's the section in question: http://www.youtube.com/watch?v=Mn4I-f34cTI Vis

What Is the “God Particle”?

“The God Particle” is a sexy name, but many physicists absolutely hate it. It’s also led people to think that maybe the discovery of the Higgs boson has something to do with the search for God, but it doesn’t. Its discovery isn’t evidence of any sort of higher being and that’s not why scie

Why Heisenberg Worked for Hitler

In 1939, Werner Heisenberg joined the "Uranium Club" to try to make a nuclear bomb for Hitler. Why? He didn't love the Nazis and he had plenty of opportunities to leave. This is the story of the moral failings of a brilliant man. My Patreon Page (thanks!): https://www.patreon.com/user?u=

A generalization of Dirac’s equation is presented, incorporating the three-valued colour variable in a way which makes it intertwine with the Lorentz transformations. We show how the Lorentz-Poincaré group must be extended to accomodate both SU(3) and the Lorentz transformations. Both symm

Ara Sedrakyan - Three dimensional Ising model as a non-critical string theory

I will discuss the sign factor problem in the 3D gauge Ising model, present the corresponding fermionic model on random surfaces, which leads to the formulation of non-critical fermionic string theory on the basis of induced Dirac action. I will demonstrate how the sign factor model is lin
