Keywords : Four-parameter interaction * Irreversible quantum graph * Smilansky-Solomyak model
OECD category: Applied mathematics
Using a technique introduced by Sergei Naboko, we analyze a generalization of the parameter-controlled model of spectral transition, originally proposed by Smilansky and Solomyak, to the situation where the singular interaction responsible for the effect is characterized by the ‘full’ family of four real numbers with the ‘diagonal’ part of the coupling being position-dependent.
