pygpe.scalar.wavefunction.ScalarWavefunction

class pygpe.scalar.wavefunction.ScalarWavefunction(grid)

Represents the scalar BEC wavefunction. This class contains the wavefunction array, in addition to various useful functions for manipulating and using the wavefunction.

Parameters:

grid (Grid) – The numerical grid.

Variables:

• component – The real-space wavefunction array.

• fourier_component – The Fourier-space wavefunction array.

• atom_num – The atom number of the condensate.

• grid – Reference to the grid object of the simulation.

__init__(grid)

Constructs the wavefunction object.

Methods

__init__(grid)	Constructs the wavefunction object.
add_noise(mean, std_dev)	Adds noise to the wavefunction using a normal distribution.
apply_phase(phase, **kwargs)	Applies a phase to the wavefunction.
density()	return: An array of the condensate density.
fft()	Fourier transforms real-space component and updates Fourier-space component.
ifft()	Inverse Fourier transforms Fourier-space component and updates real-space component.
set_wavefunction(wavefunction)	Sets the wavefunction to the specified state.
