Gauging Higher Derivatives

Instantaneous Higher Order Phase Derivatives

We present methods, based on the short time Fourier transform, which may be used to analyze the structure of multicomponent FM modulated signals instantaneously in time and frequency. The methods build on previously presented cross-spectral methods. In this paper, we introduce the concept of higher order short time Fourier transform phase derivatives, which may be used to estimate signal trajec...

electrodynamics, regularized by higher derivatives.

Two-loop renormalization of N = 1 supersymmetric electrodynamics, regularized by higher derivatives. Abstract Two-loop β-function and anomalous dimension are calculated for N = 1 supersymmetric quantum electrodynamics, regularized by higher derivatives in the minimal subtraction scheme. The result for two-loop contribution to the β-function appears to be equal to 0, does not depend on the form ...

5D Attractors with Higher Derivatives

We analyze higher derivative corrections to attractor geometries in five dimensions. We find corrected AdS3 × S geometries by solving the equations of motion coming from a recently constructed four-derivative supergravity action in five dimensions. The result allows us to explicitly verify a previous anomaly based derivation of the AdS3 central charges of this theory. Also, by dimensional reduc...

Quantum gauging from classical gauging of nonlinear algebras.

We extend our previous theory of the gauging of classical quadratically nonlinear algebras without a central charge but with a coset structure, to the quantum level. Inserting the minimal anomalies into the classical transformation rules of the currents introduces further quantum corrections to the classical transformation rules of the gauge fields and currents which additively renormalize the ...
