given the Hamiltonian [tex] H=p^{2}- \omega x^{2} [/tex](adsbygoogle = window.adsbygoogle || []).push({});

we can see inmediatly that this Hamiltonian will NOT have a BOUND state due to a 'saddle point' on (0,0) , here 'omega' is the frecuency of the Harmonic oscillations

the classical solutions are not PERIODIC [tex] Asinh( \omega t) +Bcosh( \omega t) [/tex]

The Quantum counterpart is even worse since the functions will NOT be on [tex] L^{2} (-\infty , \infty ) [/tex] then how is the spectrum ?

is there any webpage where this oscillator is considered ? What applications can be found ??
