"Generalized quantum baker maps as perturbations of a simple kernel"
L. Ermann and M. Saraceno
Phys. Rev. E 74(4) (2006) 046205/1-10
We present a broad family of quantum baker maps that generalize the proposal of Schack and Caves to any even Hilbert space with arbitrary boundary conditions. We identify a structure, common to all maps consisting of a simple kernel perturbed by diffraction effects. This “essential” baker's map has a different semiclassical limit and can be diagonalized analytically for Hilbert spaces spanned by qubits. In all cases this kernel provides an accurate approximation to the spectral properties -eigenvalues and eigenfunctions- of all the different quantizations.
