Statistics of resonance width shifts as a signature of eigenfunction nonorthogonality.
We consider an open (scattering) quantum system under the action of a perturbation of its closed counterpart. It is demonstrated that the resulting shift of resonance widths is a sensitive indicator of the nonorthogonality of resonance wave functions, being zero only if those were orthogonal. Focusing further on chaotic systems, we employ random matrix theory to introduce a new type of parametr...
متن کاملResonance trapping and saturation of decay widths
Resonance trapping appears in open many-particle quantum systems at high level density when the coupling to the continuum of decay channels reaches a critical strength. Here a reorganization of the system takes place and a separation of different time scales appears. We investigate it under the influence of additional weakly coupled channels as well as by taking into account the real part of th...
متن کاملEigenfunction Statistics of Complex Systems: A Single Parametric Formulation
We derive a common mathematical formulation for the eigenvector statistics of Hermitian operators, represented by a multi-parametric probability density. The system-information in the formulation enters through a single function of all system parameter, thus indicating a single parameter scaling of the statistics. This in turn reveals a deep rooted universality hidden underneath the world of co...
متن کاملResonance widths in open microwave cavities studied by harmonic inversion.
From the measurement of a reflection spectrum of an open microwave cavity, the poles of the scattering matrix in the complex plane have been determined. The resonances have been extracted by means of the harmonic inversion method. By this, it became possible to resolve the resonances in a regime where the linewidths exceed the mean level spacing up to a factor of 10, a value inaccessible in exp...
متن کاملSemi-parametric estimation of shifts
AbstractWe observe a large number of functions differing from each other only by a translation parameter. While the main pattern is unknown, we propose to estimate the shift parameters using M -estimators. Fourier transform enables to transform this statistical problem into a semi-parametric framework. We study the convergence of the estimator and provide its asymptotic behavior. Moreover, we u...
