Accurate eigenvalues of bounded oscillators

We calculate accurate eigenvalues of a bounded oscillator by means of the Riccati–Padé method that is based on a rational approximation to a regularized logarithmic derivative of the wavefunction. Sequences of roots of Hankel determinants approach the model eigenvalues from below with remarkable convergence rate.

Oscillators, Hysteresis and ”frozen Eigenvalues”

The aim of this tutorial is to provide insight in the mechanism behind the behaviour of oscillators. A 10MHz negative resistance oscillator is used as an example. A hysteresis phenomena in connection with the negative resistance characteristic is found. By means of piece wise linear modeling and the ”frozen eigenvalues” approach sinusoidal oscillations are investigated.

On the eigenvalues of some nonhermitian oscillators

We consider a class of one-dimensional nonhermitian oscillators and discuss the relationship between the real eigenvalues of PT-symmetric oscillators and the resonances obtained by different authors. We also show the relationship between the strong-coupling expansions for the eigenvalues of those oscillators. Comparison of the results of the complex rotation and the Riccati-Padé methods reveals...

Accurate Eigenvalues for Fast Trains

Vibration Analysis of Rails Excited by High-Speed Trains. This was the topic of talks by Volker Mehrmann and Christian Mehl from the Technical University of Berlin. In collaboration with the company SFE they study the resonances when rail tracks are excited by high speed trains, the goal being to reduce noise and vibrations in the trains. The new ICE trains travel across Europe at speeds as hig...

Accurate eigenvalues of certain sign regular matrices

We present a new O(n3) algorithm for computing all eigenvalues of certain sign regular matrices to high relative accuracy in floating point arithmetic. The accuracy and cost are unaffected by the conventional eigenvalue condition numbers. A matrix is called sign regular when the signs of its nonzero minors depend only of the order of the minors. The sign regular matrices we consider are the one...
