Class documentation

class SpawnNonAdiabaticPropagator.SpawnNonAdiabaticPropagator(propagator, potential, packet, leading_component, parameters)

This class can numerically propagate given initial values in a potential . The propagation is done for several given homogeneous Hagedorn wavepackets neglecting interaction.

get_number_components()

Returns:The number of components of .

get_number_packets()

Get the number of packets taking part in the simulation.

Returns:The number of packets currently taking part in the simulation.

get_potential()

Returns:The MatrixPotential instance used for time propagation.

get_wavepackets(packet=None)

Retrieve the wavepackets taking part in the simulation.

Parameters:packet (Integer) – The number of a single packet that is to be returned. Returns:A list of HagedornWavepacket instances that represents the current wavepackets.

number_components = None

The number of components the wavepacket has got.

oracle = None

The condition which determines when to spawn.

packets = None

The list of HagedornWavepacket taking part in the simulation.

potential = None

The potential the packet(s) feel.

propagate(time)

Given the wavepacket at time compute the propagated wavepacket at time . We perform exactly one timestep here. At every timestep we check the spawning condition.

should_spwan()

Check if there is a reason to spawn a new wavepacket.

spawn(info)

Really spawn the new wavepackets . This method appends the new HagedornWavepacket instances to the list packets of packets.
