Josephson Effect and Isomonodromic Deformations
arXiv:1805.11759
Abstract
We consider some properties of double confluent Heun equation related to the Josephson Effect. In particular, we prove that adjacency points of phased-locked areas on a parameter plane can be described via poles of Bessel solution of Painleve 3 equation.
