Axion field influence on Josephson junction quasipotential
Roberto Grimaudo, Davide Valenti, Bernardo Spagnolo +3
The direct effect of an axion field on Josephson junctions is analyzed through the consequences on the effective potential barrier that prevents the junction from switching from th…
Axion-induced oscillations in Josephson qubits
Roberto Grimaudo, Claudio Guarcello, Giovanni Filatrella +2
An effective quantum description of the axion is proposed as a two-level dynamic system together with a spin-spin Hamiltonian for a coupled axion-Josephson qubit system. The intera…
Josephson junction-based axion detection through resonant activation
Roberto Grimaudo, Davide Valenti, Bernardo Spagnolo +2
We discuss the resonant activation phenomenon on a Josephson junction due to the coupling of the Josephson system with axions. We show how such an effect can be exploited for axion…
