Dissipation Can Enhance Quantum Effects, Phys.
 









Excerpts: Usually one finds that dissipation tends to make a quantum system more
classical in nature. We study the effect of momentum dissipation on a quantum
system. (...) For a parabolic barrier, momentum coupling causes an increase in
the unstable normal mode barrier frequency, as compared to the lowering of the
barrier frequency in the presence of purely spatial coupling. This increase in
the frequency leads to an enhancement of the thermal tunneling flux, which below
the crossover temperature becomes exponentially large.
