Chapter 5: The Wigner Representation
Coherent state and squeezed states in a harmonic potential
The wavefunctions,
correspond to those in the animations of Ch. 3.
A.
Wigner representation of a squeezed state
In coordinate space the distribution proceeds from narrow to broad to narrow, twice per period.
B.
Wigner representation of a coherent state
The width of the distribution is constant both in coordinate and momentum space.
C.
Wigner representation of an "anti-squeezed" state
In coordinate space the distribution proceeds from broad to narrow to broad, twice per period.
