摘要：
In this study, we carried out the analysis of the quantum fluctuations on Josephson junction (JJ) dynamics with unconventional current-phase relation (CPR). We analyzed two case CPR: anharmonic term case and the case of Majorana term. The expression was obtained for the escape rate in macroscopic tunneling regime. It is shown that the changing of the escape rate JJ with unconventional CPR is determined by the renormalized critical current of JJ. Published under license by AIP Publishing.
