Accurate eigenvalues of bounded oscillators
نویسنده
چکیده
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.

Accurate calculation of resonances in multiple–well oscillators
Quantum–mechanical multiple–well oscillators exhibit curious complex eigenvalues that resemble resonances in models with continuum spectra. We discuss a method for the accurate calculation of their real and imaginary parts.
متن کاملAn Analytical Technique for Solving Nonlinear Oscillators of the Motion of a Rigid Rod Rocking Bock and Tapered Beams
In this paper, a new analytical approach has been presented for solving strongly nonlinear oscillator problems. Iteration perturbation method leads us to high accurate solution. Two different high nonlinear examples are also presented to show the application and accuracy of the presented method. The results are compared with analytical methods and with the numerical solution using Runge-Kutta m...
متن کاملOn 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...
متن کاملSolution of Nonlinear Hardening and Softening type Oscillators by Adomian’s Decomposition Method
A type of nonlinearity in vibrational engineering systems emerges when the restoring force is a nonlinear function of displacement. The derivative of this function is known as stiffness. If the stiffness increases by increasing the value of displacement from the equilibrium position, then the system is known as hardening type oscillator and if the stiffness decreases by increasing the value of ...
متن کاملOscillators, 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.
