The operator we call a-hat is defined as a-hat = (2m hbar w) -0.5 ( ip + mwx ), where x and p are our usual position and momentum operators.
1. What is the unit of a-hat?
2. What is a-hat dagger (the adjoint of a-hat)? Is it Hermitian?
3. What combination of a-hat, a-hat dagger, and suitable constants looks like the harmonic oscillator Hamiltonian? How close can you get it?
