A note on macroscopic quantum tunnelling with dissipation

  • A. M. Jayannavar


It is shown that dissipation decreases the quantum tunnelling amplitude. Our treatment is based on frictional Hamiltonian methods. A result similar to that of Caldeira and Leggett has been obtained in an appropriate limit.
