The quantum-optical Josephson interferometer
The photon-blockade effect, where nonlinearities at the single-photon level alter the quantum statistics of light emitted from a cavity1, has been observed in cavity quantum electrodynamics experiments with atomic2,3 and solid-state systems4–8. Motivated by the success of single-cavity quantum electrodynamics experiments, the focus has recently shifted to the exploration of the rich physics pro...
متن کاملUnconventional Josephson signatures of Majorana bound states.
A junction between two topological superconductors containing a pair of Majorana fermions exhibits a "fractional" Josephson effect, 4π periodic in the superconductors' phase difference. An additional fractional Josephson effect, however, arises when the Majorana fermions are spatially separated by a superconducting barrier. This new term gives rise to a set of Shapiro steps which are essentiall...

متن کاملPhenomenology and dynamics of a Majorana Josephson junction
Recently, attention has been paid to proposals of solid-state realizations of Majorana fermions. While the first proposal1 concerned non-Abelian excitations in a 5/2 fractional quantum Hall effect (FQHE) in semiconductor heterostructures, most proposals2,3 exploited exotic superconductors where Majorana fermions correspond to zero-energy states of an effective Bogoliubov–de Gennes (BdG) Hamilto...
