1. 1. On the (1/2,1/2) Representation of the Lorentz Group and the Discrete CPT Symmetries

   University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Author : Nikolaj Skog Pirinen; [2021]
   Keywords : The Lorentz Group; Group Theory; Quantum Field Theory; CPT; Symmetry; Spinors; Representation Theory; Physics and Astronomy;

   Abstract : This thesis derives the explicit form of the elements of the (1/2,1/2) representation of the Lorentz group, by actually performing a direct product of the chiral (1/2,0)- and (0,1/2)-representations. The Lorentz transformations of fourvectors are thereafter recovered from this direct-product representation, allowing the derivation of a transformation matrix between the fourvector- and direct product basis.

3. 2. The Dirac Equation for a Particle in a Spherical Box Potential with Application in Bag Modeling

   University essay from KTH/Teoretisk fysik

   Author : Emil Blomquist; Trotte Boman; [2015]
   Keywords : ;

   Abstract : The Dirac equation is a relativistic wave equation and was the first equation to capture spin in relativistic quantum mechanics. Here, the Dirac equation will be derived and solved for a particle in a spherical box potential. READ MORE

4. 3. Retardation effects in fundamental physics

   University essay from Teoretisk fysik

   Author : Fredrik Härlin; [2011]
   Keywords : shift; dirac equation; klein gordon equation; retardation; fundamental physics; retardation; dirac ekvationen; klein gordon ekvationen; fundamental fysik;

   Abstract : Speculations in the signicance of retardation aects in fundamental physics, especiallythe Dirac equation, that Atiyah and Moore bring up in "A shifted view of fundamental physics" are summarized and reviewedin terms of basic undergraduate conceptions. Some remarks are further investigated and ashifted version of the Klein Gordon equation is derived. READ MORE
