WebOur intuition which regards the above phenomenon as a macroscopic tunneling does not rely on the number of collective degrees of freedom such as the center of mass but on the number of microscopic degrees of freedom such as the positions of constituent atoms.
WebMacroscopic resonant tunneling (MRT) [6,7] is an im-portant probe of quantum effects in Josephson junction-based devices. In an MRT experiment, flux tunnels be-tween two wells of a double well potential when energy levels are aligned.
