Query: Chiral topological superconductivity in Josephson junction   We consider a heterostructure of semiconductor layers sandwiched between two
superconductors, forming a two-dimensional Josephson junction. Applying a
Zeeman field perpendicular to the junction can render a topological
superconducting phase with chiral Majorana edge mode. We show that the phase
difference between two superconductors can efficiently reduce the magnetic
field required to achieve the chiral topological superconductivity, providing
an experimentally feasible setup to realize chiral Majorana edge modes. We also
construct a lattice Hamiltonian of the setup to demonstrate the chiral Majorana
edge mode and the Majorana bound state localized in vortices.
