Two-component BEC wavefunction#
The two-component BEC wavefunction class contains the wavefunction arrays plus an assortment of useful functions for manipulating and using the wavefunction.
Constructing the Wavefunction object is done through the constructor
|
Here, the parameter grid is a Grid object defined prior to instantiating the Wavefunction class.
Wavefunction methods#
Initial state#
Below are the methods associated with the initial state.
Set the wavefunction components to the specified arrays. |
|
|
Adds noise to the specified wavefunction components using a normal distribution. |
|
Applies a given phase to the specified condensate components. |
The set_wavefunction method is used to set the initial state of the two-component system.
The add_noise method adds noise to each grid point of the wavefunction for the specified components. The noise is drawn from a uniform distribution with the mean and standard deviation specified in the function signature. Finally, apply_phase applies a user-defined phase to the specified wavefunction components as \(\psi_m\rightarrow\psi_m e^{i\phi}\) for phase \(\phi\) and component \(m \in \{1, 2\}\).
Other methods#
The methods below fall under the miscellaneous category and are self-explanatory.
Fourier transforms real-space components and updates Fourier-space components. |
|
Inverse Fourier transforms Fourier-space components and updates real-space components. |
|
|
Calculates the density of the specified component(s). |
