Parity
Parity
is a parameter for AtomicState that specifies the parity of the state.
Parity[state]
returns the value specified for Parity in AtomicState state, or Parity[StateLabel[state]] if it is not specified.
Details and Options
- Possible values for Parity are Even and Odd.
- Parity is automatically threaded over a list of AtomicState objects appearing as its argument.
- The value of Parity is used to determine which states are coupled by the E1 Hamiltonian.
Examples
Basic Examples (1)
A three level system with two even-parity states and one odd-parity state:
Opposite-parity states are coupled by the E1 Hamiltonian, but same-parity states are not:
By default, LevelDiagram puts even-parity states on the left and odd-parity states on the right:
