What are the properties and characteristics of a half quantum harmonic oscillator?
A half quantum harmonic oscillator is a quantum system that exhibits properties of both classical harmonic oscillators and quantum mechanics. It has energy levels that are quantized in half-integer values, unlike integer values in regular quantum systems. This leads to unique characteristics such as fractional energy levels and non-integer spin values.

What are the properties and significance of wave functions of harmonic oscillator in quantum mechanics?
The wave functions of a harmonic oscillator in quantum mechanics describe the probability distribution of finding a particle at different positions and energies.

What is the relationship between the harmonic oscillator ladder operator and the energy levels of a quantum harmonic oscillator system?
The harmonic oscillator ladder operator is a mathematical tool used to find the energy levels of a quantum harmonic oscillator system. By applying the ladder operator to the wave function of the system, one can determine the energy levels of the oscillator. The ladder operator helps in moving between different energy levels of the system.
Why equipartion of energy is not valid for quantum harmonic oscillator?
Equiartition of energy assumes that each degree of freedom in a system contains the same average energy. However, in the quantum harmonic oscillator, the energy levels are quantized due to the discreteness of allowed energy levels in quantum mechanics. This leads to energy being restricted to certain specific values, rather than being continuously distributed among all possible states as assumed in classical physics.
