I'd claim Majorana in 2, 3,4 mod 8, but pseudo-Majorana in 0,1,2 mod 8, with p-majorana being necessarily massless as the pseudo "charge conjugation" flips the sign of $\bar\psi \psi$ while the usual one leaves $\bar\psi \psi$ invariant. ...

WebIn mathematical physics, the gamma matrices, , also called the Dirac matrices, are a set of conventional matrices with specific anticommutation relations that ensure they generate … WebOct 26, 2016 · This means that the eigenvalues of $\bar{\Gamma}$, the chirality, is $+1$ if there is a even number of occupied modes and is $-1$ for odd. Since this matrix commutes with Lorentz generator, for even dimensions we may split a Dirac spinor into two spinors, a chiral spinor ($\bar\Gamma =+1$) and anti-chiral spinor ($\bar\Gamma =-1$).
WebApr 13, 2024 · Mueller matrix polarimetry is a widely used optical technique for the characterization of materials, whether it is a known or unknown object. The \(4 \times 4\) Mueller matrix is characteristic of each optical medium and the transmitted light has properties that depend on the interaction it has undergone with the testing medium. In an … WebAug 6, 2015 · In (1+1) there is no problem defining chirality. A common representation of the Clifford algebra in terms of the Pauli matrices is. γ 0 = σ 2. γ 1 = − i σ 1, This is a nice …
WebIn particle physics, chiral symmetry breaking is the spontaneous symmetry breaking of a chiral symmetry – usually by a gauge theory such as quantum chromodynamics, the quantum field theory of the strong interaction.
In geometry, a figure is chiral (and said to have chirality) if it is not identical to its mirror image, or, more precisely, if it cannot be mapped to its mirror image by rotations and translations alone. An object that is not chiral is said to be achiral. A chiral object and its mirror image are said to be enantiomorphs. … See more Some chiral three-dimensional objects, such as the helix, can be assigned a right or left handedness, according to the right-hand rule. Many other familiar objects exhibit the same chiral … See more A figure is achiral if and only if its symmetry group contains at least one orientation-reversing isometry.
