Massive Spin 3 / 2 Electrodynamics
We study the general non-minimally coupled charged massive spin 3/2 model both for its low energy phenomenological properties and for its unitarity, causality and degrees of freedom behaviour. When the model is viewed as an effective theory, its parameters (after ensuring the correct excitation count) are related to physical characteristics, such as the magnetic moment g factor, by means of low...
متن کاملMassless and Massive Vector Goldstone Bosons in Nonlinear Quantum Electrodynamics
The spontaneous Lorentz invariance violation (SLIV) developing in QED type theories with the nonlinear four-vector field constraint A μ = M (where M is a proposed scale of the Lorentz violation) is considered in the case when the internal U(1) charge symmetry is also spontaneously broken. We show that such a SLIV pattern induces the genuine vector Goldstone boson which appears massless when the...

We study the general non-minimally coupled charged massive spin 3/2 model both for its low energy phenomenological properties and for its unitarity, causality and degrees of freedom behavior. When the model is viewed as an effective theory, its parameters ~after ensuring the correct excitation count! are related to physical characteristics, such as the magnetic moment g factor, by means of low ...
متن کاملMass and Spin Renormalization in Lorentz Electrodynamics
Lorentz’ objection to the Uhlenbeck-Goudsmit proposal of a spin magnetic moment of the electron, namely that the electron’s equatorial rotation speed would exceed the speed of light by a factor ≈ 10, mutated into an objection against Lorentz electrodynamics (LED) itself when the spin magnetic moment became established. However, Lorentz’ renormalization calculation, based on the early 20th centu...
متن کاملSpin-liquid condensate of spinful bosons.
We introduce the concept of a bosonic spin liquid condensate (SLC), where spinful bosons in a lattice form a zero-temperature spin disordered charge condensate that preserves the spin rotation symmetry, but breaks the U(1) symmetry due to a spinless order parameter with charge one. It has an energy gap to all the spin excitations. We show that such SLC states can be realized in a system of spin...
