(a) The quantum [solid line, given by equation (8)] and the classical (dashed line) probability density function for the weak anharmonic potential (a = 0.05, b = 0.1) at T = 0.1. (b) The same graph as (a) except for T = 2.0. (c) The same graph except for the strong anharmonic potential (a = 2.5, b = 5.0) at T = 0.1. (d) The same graph as (c) except for T = 2.0. |
