About the `Observables` class¶

The WaveBlocks Project

class WaveBlocksND.Observables[source]¶

This class is the interface definition for general observable computation procedures.

kinetic_energy(ket, T)[source]¶

Compute the kinetic energy $E_{\text{kin}} := \langle\psi|T|\psi\rangle$ .

Parameters:	ket – The object denoted by $\psi$ . T – The kinetic energy operator $T$ .
Raise:	`NotImplementedError` Abstract interface.

norm(ket)[source]¶

Compute the $L^2$ norm $\sqrt{\langle\psi|\psi\rangle}$ .

Parameters:	ket – The object denoted by $\psi$ .
Raise:	`NotImplementedError` Abstract interface.

potential_energy(ket, potential)[source]¶

Compute the potential energy $E_{\text{pot}} := \langle\psi|V|\psi\rangle$ .

Parameters:	ket – The object denoted by $\psi$ . potential – The potential $V(x)$ .
Raise:	`NotImplementedError` Abstract interface.
