Operator Gauge Symmetry in QED [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2006 In this paper, operator gauge transformation, first introduced by Kobe, is applied to Maxwell's equations and continuity equation in QED. The gauge invariance is satisfied after quantization of electromagnetic fields.

Models of Quadratic Algebras Generated by Superintegrable Systems in 2D [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2011 In this paper, we consider operator realizations of quadratic algebras generated by second-order superintegrable systems in 2D. At least one such realization is given for each set of Stäckel equivalent systems for both degenerate and nondegenerate ...

Spin-other-orbit operator in the tensorial form of second quantization [PDF]
Physica Scripta, 1998 The tensorial form of the spin-other-orbit interaction operator in the formalism of second quantization is presented. Such an expression is needed to calculate both diagonal and off-diagonal matrix elements according to an approach, based on a ...

Hyperfine structure operator in the tensorial form of second quantization
Open Physics, 2004 AbstractThe general tensorial form of the hyperfine interaction operator in the formalism of second quantization is presented. Both diagonal and off-diagnonal matrix elements of the above-mentioned operator are found using an approach based on a combination of second quantization in the coupled tensorial form, angular momentum theory in three spaces ...

Majorana Mass Term of Majorana Spinors
Physical Sciences Forum, 2023 We have proven that, under the standard charge conjugation approach, the Majorana mass term in QFT must vanish. We have derived formulas for the Majorana spinor field operator without any assumptions about the second quantization procedure. The fact that

Switching Quantum Reference Frames for Quantum Measurement [PDF]
Quantum, 2020 Physical observation is made relative to a reference frame. A reference frame is essentially a quantum system given the universal validity of quantum mechanics. Thus, a quantum system must be described relative to a quantum reference frame (QRF). Further
