Quantum Electrodynamics without Infinities
The use of a fermion Green’s function involving no delta functions is demonstrated. This Green’s function is employed to compute the first order contribution to the vacuum polarization of the hydrogen Lamb shift. No infinities appear so that regularization is unnecessary. The numerical value of this contribution to the vacuum polarization is shown to be identical to the value obtained by regula...
متن کاملOblique Boundary Conditions in Quantum Electrodynamics
The heat kernel coefficients corresponding to QED with boundary conditions that depend on tangential derivatives —as is the case when adding a Chern-Simons boundary action to the ordinary Maxwell volume term— are calculated explicitly.

متن کاملLasing without inversion in circuit quantum electrodynamics.
We study the photon generation in a transmission line oscillator coupled to a driven qubit in the presence of a dissipative electromagnetic environment. It has been demonstrated previously that a population inversion in the qubit can lead to a lasing state of the oscillator. Here we show that the circuit can also exhibit the effect of "lasing without inversion." It arises since the coupling to ...
متن کاملConstructive negation without subsidiary trees
In this paper we propose a new operational semantics, called BCN, which is sound and complete with respect to Clark-Kunen's completion for the unrestricted class of Normal Logic Programs. BCN is based on constructive negation and can be seen as an operational semantics for the class of Normal Constraint Logic Programs (NCLP) over the Herbrand universe. The main features of BCN making it a usefu...
متن کاملQuantum Electrodynamics on Noncommutative Spacetime
We propose a new method to quantize gauge theories formulated on a canonical noncommutative spacetime with fields and gauge transformations taken in the enveloping algebra. We show that the theory is renormalizable at one loop and compute the beta function and show that the spin dependent contribution to the anomalous magnetic moment of the fermion at one loop has the same value as in the commu...
