Non-square Hamiltonians and perturbation series for quasi-exact oscillators
نویسنده
چکیده
For the general polynomial potentials, quasi-exact states (for which the wavefunctions resemble harmonic oscillators) are known to exist in principle but their construction proves often prohibitively complicated in practice. An innovative and universal perturbative approach to this old and challenging problem is proposed, based on a thorough modification of the standard textbook Rayleigh-Schrödinger recipe.

Perturbation method for non-square Hamiltonians and its application to polynomial oscillators
A remarkable extension of Rayleigh-Schrödinger perturbation method is found and described. Its (N + q)× (N + 1)−dimensional Hamiltonians are assumed emerging during quasi-exact constructions of bound states. At all q > 1, the role of the traditional single eigenvalue is taken over by an energy/coupling q−plet. In a way circumventing both the non-linearity and non-Hermiticity difficulties, the c...
متن کاملModified homotopy perturbation method for solving non-linear oscillator's equations
In this paper a new form of the homptopy perturbation method is used for solving oscillator differential equation, which yields the Maclaurin series of the exact solution. Nonlinear vibration problems and differential equation oscillations have crucial importance in all areas of science and engineering. These equations equip a significant mathematical model for dynamical systems. The accuracy o...
متن کاملPower Series -Aftertreatment Technique for Nonlinear Cubic Duffing and Double-Well Duffing Oscillators
Modeling of large amplitude of structures such as slender, flexible cantilever beam and fluid-structure resting on nonlinear elastic foundations or subjected to stretching effects often lead to strongly nonlinear models of Duffing equations which are not amendable to exact analytical methods. In this work, explicit analytical solutions to the large amplitude nonlinear oscillation systems of cub...
متن کاملInverse dimension expansions
Two toy Hamiltonians of anharmonic oscillators are considered. Both of them are found exactly solvable not only in the limit of infinite spatial dimension D but also in the next D ≫ 1 approximation. This makes all their bound states tractable via perturbation series in 1/ √ D ≪ 1.
متن کاملOn The Simulation of Partial Differential Equations Using the Hybrid of Fourier Transform and Homotopy Perturbation Method
In the present work, a hybrid of Fourier transform and homotopy perturbation method is developed for solving the non-homogeneous partial differential equations with variable coefficients. The Fourier transform is employed with combination of homotopy perturbation method (HPM), the so called Fourier transform homotopy perturbation method (FTHPM) to solve the partial differential equations. The c...
