4 Complex harmonic potential
(g) ω = 1.2 (h) ω = 1.4
(i) ω = 1.5 (j) ω = 1.6
(k) ω = 1.8 (l) ω = 2.0
Figure 4.2: Real and imaginary part of the lowest six states as a function of the dissipation
strength c of the imaginary potential. Two curves with the same colour represent the real and
imaginary part of the energy of the state, where the real part starts at ε R (c = 0) = 2m − 1 and
the imaginary part at ε I (c = 0) = 0. Moreover, ε ∞ -states are counted by integer n while ε 0 -states
are counted by integer k.
