Quantum tunneling in dissipative systems
Physical Review A, 1993As a prelude to a discussion of tunneling in the presence of dissipation, we discuss the damped harmonic oscillator. We show that for a harmonic-oscillator potential, the Caldeira-Leggett Hamiltonian can be reduced to a sum of independent harmonic-oscillator Hamiltonians by a normal-mode transformation.

Quantum uncertainty effect in tunneling
Physical Review Letters, 1991It is shown that electron tunneling from a very narrow tip should be effected, in an essential manner, by the quantum uncertainty in its transverse momentum induced by the confinement in the tip. This effect produces a strong asymmetry in the current-voltage characteristics of the tunnel junction, and to other unusual consequences.

Quantum tunneling is een ideaal onderwerp om de verschillende begrippen van de quantumfysica samen te brengen in een tweetal lessen: golfeigenschappen van deeltjes, golffunctie en waarschijnlijkheidsverdeling, en energiebarrières. En wat denken leerlingen bij deze begrippen? Dat krijgen we handig te zien in het logboek van hun digitale antwoorden.

Abstract Quantum tunneling, wherein a quanject has a non-zero probability of tunneling into and then exiting a barrier of finite width and height, is the subject of Chapter 13. The description for the one-dimensional case is extended to the barrier being inverted, which forms an attractive potential well.

Realism and quantum flux tunneling
Physical Review Letters, 1987Leggett and Garg have argued that the phenomenon of quantum flux tunneling oscillations will, according to the predictions of quantum mechanics, contradict the pair of assumptions ``macroscopic realism'' and ``noninvasive measurability.'' It is argued here that there can be no contradiction of realism in such a case, and that the contradiction is ...

Quantum tunneling in a dissipative system
Physical Review A, 1996Applying a technique developed recently [L. H. Yu and C. P. Sun, Phys. Rev. A {bold 49}, 592 (1994); L. H. Yu, Phys. Lett. {bold 202}, 167 (1995)] for a harmonic oscillator coupled to a bath of harmonic oscillators, we present an exact solution for the tunneling problem in an Ohmic dissipative system with inverted harmonic potential.
