Welcome to the time-evo-ion wiki! The main purpose of this code is to:

  1. Simulate heating of an atom trapped in a static harmonic potential
  2. Simulate a measurement of the heating rate using Rabi flops

The heating simulation code is taken directly from the Qutip's pdf documentation, '3.6.5 Example: Harmonic Oscillator in Thermal Bath' with Qutip's mesolve() function, which uses the Lindblad Master Equation, a thermal reservoir @ room temperature, and a coupling coefficient such that the heating rate is ~0.6 quanta/ms (kinda arbitrary but we see this in experiment, although when the trap is clean we see as low as ~200-300 quanta/ms @1MHZ,72um above the surface, which means the coupling coefficient should be reduced accordingly).

The Rabi flops are generated using the 'self.gen_flops()' function.
