Description

We study a topological superconductor capable of exchanging particles with an environment. The isolated superconductor is known to undergo a phase transition, which vanishes when the system is coupled to an environment. However, we show how signatures of the phase transition can still be observed, playing an important role in the particle-exchange mechanism.

These results are obtained by modelling the system with an integrable Hamiltonian, building on the class of Richardson-Gaudin models, and the mean-field description of the phase transition is linked with the exact solution of the model in order to obtain an accurate description of this mechanism.
