S. Baskoutas et al., DISSIPATIVE TUNNELING OF THE INVERTED CALDIROLA-KANAI OSCILLATOR, Journal of physics. A, mathematical and general, 27(6), 1994, pp. 2189-2196
We discuss, in the phase time approach, quantum tunnelling in the pres
ence of dissipation for an inverted oscillator with Caldirola-Kanai da
mping. The exact expressions of time delay, traversal time and effecti
ve tunnelling velocity are derived. Some paradoxical aspects of tunnel
ling related to the particle speed in crossing the barrier-such as the
Hartmann-Fletcher effect-are briefly considered.
