Abstract

Within the well-established quantum picture of Josephson junctions, we study the possibility of resonant macroscopic quantum tunneling. Expressions for the Lifetime of metastable states are obtained and the effects of temperature on the main features of the phenomenon are discussed. A ''saturation temperature'' for the process, below which any temperature effect is negligible, is identified. Quantitative considerations are also given on the actual experimental accessibility to these measurements.
