The deformative effect of phonon states of the bath in a dissipative quantum tunneling system is studied by perturbation and a variational approach. We find that the deformative effect depends on the dimension of the bath. It increases as the dimension is reduced on one hand. On the other hand,it gives more stronger influence on the quantum tunneling system for a lower-dimensional bath.

The influence of a nonlinear dissipation mechanism on the dynamics of a particle, which performs tunneling through a potential barrier, is investigated. The particular dissipation mechanism considered contains terms quadratic in the normal modes of the heat bath, in addition to linear couplings. The nonlinear terms are shown to affect the incoherent tunneling rate.
