FIG. : Upper panel: adiabatic BO PESs (S0 in blue and S1 in red) as functions of ϕ, q when the system is not coupled to the bath. The contour plot represent the initial Gaussian nuclear density in ϕ, q. Lower panel: adiabatic BO potential energy curves as functions of ϕ obtained for q = 0 when the system is not coupled to the bath (S0 in blue and S1 in red) and when the system is coupled to the modes 1, 8 and 23 fixing the bath positions at x1 = 0.5, x8 = 1.0, x23 = 1.5. Vertical dashed lines highlight the positions of the CIs in the two cases.
