A hybrid setup consisting of a superconductivity-proximitized quantum spin Hall (QSH) insulator and a quantum anomalous Hall (QAH) insulator is proposed for chiral injection of electrons into the Majorana bound state (MBS). An unexplored region of the phase space involving the exchange field induced boost of the helical edge state is then proposed...

We study the ground state of a system with an interface between ν=4 and ν=3 in the quantum Hall regime. Far from the interface, for a range of interaction strengths, the ν=3 region is fully polarized but ν=4 region is unpolarized. Upon varying the strength of the interactions and the width of the interface, the system chooses one of two distinct ed...

We study the ground state of a system with an interface between $\nu=4$ and $\nu=3$ in the quantum Hall regime. Far from the interface, for a range of interaction strengths, the $\nu=3$ region is fully polarized but $\nu=4$ region is locally a singlet. Upon varying the strength of the interactions and the width of the interface, the system chooses...

The magnetic flux periodicity of hc2e is a well-known manifestation of Cooper pairing in typical s-wave superconductors. In this paper we theoretically show that the flux periodicity of a two-dimensional second order topological superconductor, which features zero-energy Majorana modes localized at the corners of the sample, is hce instead. We furt...

The magnetic flux periodicity of $\frac{hc}{2e}$ is a well known manifestation of Cooper pairing in typical s-wave superconductors. In this paper we theoretically show that the flux periodicity of a two-dimensional second-order topological superconductor, which features zero-energy Majorana modes localized at the corners of the sample, is $\frac{hc...
