Gauge invariance of the β-function in nonrelativistic quantum electrodynamics
Recently there has been much interest in gauge theories applied to condensed matter physics. I show that for a system of nonrelativistic electrons coupled to a U(1) gauge field in the presence of a Fermi surface, the β-function to one-loop order is, for a particular family of gauge-choices, independent of the gauge-choice.
متن کاملRelativistic Quantum Mechanics without Gauge Invariance
_ _. We argue that th&crossing (CPT) y s mmetry of relativistic quantum mechanics requires that both the Coulombic and the Newtonian force between pairs of particles will reverse when one is replaced by its anti-particle. For consistency, this requires a theory in which both the equivalence principle and gauge invariance are abandoned. Thus whether ant,i-hydrogen " falls " up or down will provi...
متن کاملPhysical state for non-relativistic quantum electrodynamics
A physical subspace and physical Hilbert space associated with asymptotic fields of nonrelativistic quantum electrodynamics are constructed through the Gupta-Bleuler procedure. Asymptotic completeness is shown and a physical Hamiltonian is defined on the physical Hilbert space.
متن کاملGauge Invariance in Classical Electrodynamics 1
RÉSUMÉ. Le concept de l’invariance de jauge dans l’électrodynamique classique suppose tacitement que les équations de Maxwell possèdent des solutions uniques. Mais en calculant le champ électromagnétique d’une particule en mouvement faisant usage de la jauge de Lorenz ainsi que de la jauge de Coulomb, et résolvant directement les équations des champs nous obtenons des solutions contradictoires....
متن کاملThe Renormalized Electron Mass in Non-relativistic Quantum Electrodynamics
This work addresses the problem of infrared mass renormalization for a scalar electron in a translation-invariant model of non-relativistic QED. We assume that the interaction of the electron with the quantized electromagnetic field comprises a fixed ultraviolet regularization and an infrared regularization parametrized by σ > 0. For the value p = 0 of the conserved total momentum of electron a...
