Investigation of the time evolution of Lane-emden-type Kanai-caldirola oscillator
(2009)
In this study, we have investigated the time evolution of the first kind Lane-Emden-type Kanai-Caldirola oscillator. The total energy of the one dimensional classical harmonic oscillator with time-dependent mass is obtained. ...
Investigation of the time evolutions of some log-periodic oscillators
(2010)
We consider the time evolution of the one dimensional classical and quantum oscillator systems according to its mass and spring constant with fluctuating time. By using the SU(1,1) coherent states, the classical equations ...
