Tunneling resonances in systems without a classical trapping
Original language description
In this paper, we analyze a free quantum particle in a straight Dirichlet waveguide which has at its axis two Dirichlet barriers of lengths l_(+-) separated by a window of length 2a. It is known that if the barriers are semi-infinite, i.e., we have two adjacent waveguides coupled laterally through the boundary window, the system has for any a > 0 a finite number of eigenvalues below the essential spectrum threshold. Here, we demonstrate that for large but finite l_(+-) the system has resonances which converge to the said eigenvalues as l_(+-) -> infinity, and derive the leading term in the corresponding asymptotic expansion.
