Operators and states for 1D cartesian position and momentum.

TODO:

• Add 3D classes to mappings in operatorset.py

class sympy.physics.quantum.cartesian.PositionBra3D(*args, **old_assumptions)

3D cartesian position eigenbra

classmethod dual_class()

Return the class used to construt the dual.

class sympy.physics.quantum.cartesian.PositionKet3D(*args, **old_assumptions)

3D cartesian position eigenket

classmethod dual_class()

Return the class used to construt the dual.

class sympy.physics.quantum.cartesian.PositionState3D(*args, **old_assumptions)

Base class for 3D cartesian position eigenstates

classmethod default_args()

If no arguments are specified, then this will return a default set of arguments to be run through the constructor.

NOTE: Any classes that override this MUST return a tuple of arguments. Should be overidden by subclasses to specify the default arguments for kets and operators

The y coordinate of the state

property position_z

The z coordinate of the state

class sympy.physics.quantum.cartesian.PxBra(*args, **old_assumptions)

1D cartesian momentum eigenbra.

classmethod default_args()

If no arguments are specified, then this will return a default set of arguments to be run through the constructor.

NOTE: Any classes that override this MUST return a tuple of arguments. Should be overidden by subclasses to specify the default arguments for kets and operators

classmethod dual_class()

Return the class used to construt the dual.

property momentum

The momentum of the state.

class sympy.physics.quantum.cartesian.PxKet(*args, **old_assumptions)

1D cartesian momentum eigenket.

classmethod default_args()

If no arguments are specified, then this will return a default set of arguments to be run through the constructor.

NOTE: Any classes that override this MUST return a tuple of arguments. Should be overidden by subclasses to specify the default arguments for kets and operators

classmethod dual_class()

Return the class used to construt the dual.

property momentum

The momentum of the state.

class sympy.physics.quantum.cartesian.PxOp(*args, **old_assumptions)
