Renormalizability of the (minimal) single-fermion QED extension is investigated at all orders of perturbation theory in the framework of algebraic renormalization, a regularization-independent method. Relative to the standard QED, new structures that could lead to gauge anomalies are identified. Nevertheless, even if the anomaly coefficients fail to vanish in the general case, they shall be absent provided we require invariance of the action under C and/or PT transformations. Stability is also verified in this case, hence full renormalizability is attained. ...

Author(s): M. Lermer, N. Gregersen, F. Dunzer, S. Reitzenstein, S. Höfling, J. Mørk, L. Worschech, M. Kamp, and A. Forchel We have employed Bloch-wave engineering to realize submicron diameter high quality factor GaAs/AlAs micropillars (MPs). The design features a tapered cavity in which the fundamental Bloch mode is subject to an adiabatic transition to match the Bragg mirror Bloch mode. The resulting reduced scatterin... [Phys. Rev.

O. L. de Lange, R. E. Raab, and A. Welter Implicit in the change from microscopic Electrodynamics to a macroscopic, multipole theory is a set of molecule-fixed coordinate systems and hence an arbitrary set of molecular origins {O} relative to which the positions of molecular constituents are specified. We examine the extent to which this ... [J. Math. Phys. 53, 013513 (2012)] published Fri Jan 20, 2012. ...

Jason Parsley We study steady-state magnetic fields in the geometric setting of positive curvature on subdomains of the three-dimensional sphere. By generalizing the Biot-Savart law to an integral operator BS acting on all vector fields, we show that Electrodynamics in such a setting behaves rather similarly to E ... [J. Math.

Then, the expression$\backslash frac\{1\}\{Y\}\backslash frac\{\backslash partial^2\; Y\}\{\backslash partial\; y^2\}+\backslash frac\{1\}\{Z\}\backslash frac\{\backslash partial^2\; Z\}\{\backslash partial\; z^2\}$ did not change, since that expression does not depend on x. Thus, we know that $\backslash frac\{1\}\{X\}\backslash frac\{\backslash partial^2\; X\}\{\backslash partial\; x^2\}$ must be constant. Now, suppose we vary x without changing y. Then, the expression$\backslash frac\{1\}\{Y\}\backslash frac\{\backslash partial^2\; Y\}\{\backslash partial\; y^2\}+\backslash frac\{1\}\{Z\}\backslash frac\{\backslash partial^2\; Z\}\{\backslash partial\; z^2\}$ did not change, since that expression does not depend on x. Thus, we know that $\backslash frac\{1\}\{X\}\backslash frac\{\backslash partial^2\; X\}\{\backslash partial\; x^2\}$ must be constant. − This becomes a ''ordinary'' differential equation, which is much easier to solve. In fact, it is either an exponential function, if the constant is positive, or a sinusoidal function, if the constant is negative. The sign of the constant has to be determined by the boundary conditions. + This becomes an ''ordinary'' differential equation, which is much easier to solve. In fact, it is either an ...
