    "abstract": "Quantum tunneling between two potential wells in a magnetic field can be\nstrongly increased when the potential barrier varies in the direction\nperpendicular to the line connecting the two wells and remains constant along\nthis line. A periodic structure of the wave function is formed in the direction\njoining the wells. The resulting motion can be coherent like motion in a\nconventional narrow band periodic structure. A particle penetrates the barrier\nover a long distance which strongly contrasts to WKB-like tunneling. The whole\nproblem is stationary. The coherent process can be influenced by dissipation.",
