Description

setDipole(u) sets the dipole of the harmonic oscillator to u.

Detailed Description and Examples

The dipole set via this method must be understood as a measure for how strong the modelled entity (a cavity for example) reacts to the external light. The time dependent Hamiltonian that is generated by an external field that interacts with a harmonic oscillator is given by

$$H_e(t) = E(t) \mu \cdot(\sigma^- + \sigma^+)$$

where $\sigma^-$ and $\sigma^+$ denote the lowering and raising operators.
