We propose and analyze theoretically an experimental setup for detecting the elusive Majorana particle in semiconductor-superconductor heterostructures. The experimental system consists of one-dimensional semiconductor wire with strong spin-orbit Rashba interaction embedded into a superconducting quantum interference device. We show that the energy spectra of the Andreev bound states at the junction are qualitatively different in topologically trivial (i.e., not containing any Majorana) and…

All-electrical spectroscopy of topological phases in semiconductor-superconductor heterostructures
Semiconductors in the proximity of superconductors have been proposed to support phases hosting Majorana bound states. When the systems undergo a topological phase transition towards the Majorana
Engineering of many-body Majorana states in a topological insulator/s-wave superconductor heterostructure
It is shown that MZMs can be stabilized on the ends of the ladder with the presence of tilted external magnetic field and four-Majorana interaction and a fruitful phase diagram is obtained.
Signatures of topological phase transitions in Josephson current-phase discontinuities
Topological superconductors differ from topologically trivial ones for the presence of topologically protected zero-energy modes. To date, experimental evidence of topological superconductivity in
Fractional Josephson Vortices and Braiding of Majorana Zero Modes in Planar Superconductor-Semiconductor Heterostructures.
It is shown that under certain conditions the Josephson vortices fractionalize to half-vortices, each carrying half of the superconducting flux quantum and a single Majorana zero mode, and that the system allows for a current-controlled braiding of Majoranazero modes.
Experimental phase diagram of zero-bias conductance peaks in superconductor/semiconductor nanowire devices
Tuning experiments on semiconductor nanowires coupled to superconductors are performed to establish the zero-bias peak phase in the space of gate voltage and external magnetic field and provide means for Majorana manipulation as required for braiding and topological quantum bits.
Topological superconductivity and the fractional Josephson effect in quasi-one dimensional wires on a plane
A time-reversal invariant topological superconductivity is suggested to be realized in a quasi-one-dimensional structure on a plane, which is fabricated by filling the superconducting materials into
Chiral Majorana fermion edge states in a heterostructure of superconductor and semiconductor with spin-orbit coupling
We study low-energy excitations in a device, consisting of spin-orbit coupling semiconductor, s-wave superconductor and ferromagnetic insulator. A vortex in the device generates zero-energy Majorana
Topological superconductor–Luttinger liquid junctions
Experimental evidence was recently obtained for topological superconductivity in spin–orbit coupled nanowires in a magnetic field, proximate to an s-wave superconductor. When only part of the wire
Evidence for Majorana phases in the magnetoconductance of topological junctions based on two-dimensional electron gases
We calculate the linear conductance of a two-dimensional electron gas (2DEG)-based junction between a normal semiconductor section and a hybrid semiconductor-superconductor section, under
