The chiral edge modes of a topological superconductor support two types of excitations: fermionic quasiparticles known as Majorana fermions and $\pi$-phase domain walls known as edge vortices. Edge vortices are injected pairwise into counter-propagating edge modes by a flux bias or voltage bias applied to a Josephson junction. An unpaired edge mode carries zero electrical current on average, but there are time-dependent current fluctuations. We calculate the shot noise power produced by a…

Theory of Berry Singularity Markers: Diagnosing Topological Phase Transitions via Lock-In Tomography

This work brings forward an alternative experimental approach to infer the topological character of phase transitions in insulators. This method relies on subjecting the target system to a set of

Electrical detection of the Majorana fusion rule for chiral edge vortices in a topological superconductor

Majorana zero-modes bound to vortices in a topological superconductor have a non-Abelian exchange statistics expressed by a non-deterministic fusion rule: When two vortices merge they may or they may

Topologically protected charge transfer along the edge of a chiral p-wave superconductor.

The Majorana fermions propagating along the edge of a topological superconductor with $p_x+ip_y$ pairing deliver a shot noise power of $\frac{1}{2}\times e^2/h$ per eV of voltage bias. We calculate

Deterministic Creation and Braiding of Chiral Edge Vortices.

This work proposes to use the chiral motion along the boundary of the superconductor to braid a mobile vortex in the edge channel with an immobile vortex with Majorana zero mode in the bulk.

Time-resolved electrical detection of chiral edge vortex braiding

A 2\pi2π phase shift across a Josephson junction in a topological superconductor injects vortices into the chiral edge modes at opposite ends of the junction. When two vortices are fused they

Interferometric and noise signatures of Majorana fermion edge states in transport experiments.

This work proposes to study noise correlations in a Hanbury Brown-Twiss type interferometer and finds three signatures of the Majorana nature of the channels, including an anomalously large shot noise in the output ports for a vanishing average current signal.

Half-integer charge injection by a Josephson junction without excess noise

A Josephson junction in a topological superconductor can inject a charge e/2 into a normal-metal contact, carried by chiral Majorana edge modes. Here we address the question whether this half-integer

This work shows how a pair of neutral Majorana fermions can be converted reversibly into a charged Dirac fermion, and enables electrical detection of a qubit by an interferometric measurement.

We explore a long Josephson contact transporting Cooper pairs between one-dimensional (1D) charge-neutral chiral Majorana modes in the leads via charged Dirac chiral modes in the normal region. We

A point contact formed by a superconducting junction is introduced and it is shown that its transmission can be controlled by the phase difference across the junction.

Quantized conductance at the Majorana phase transition in a disordered superconducting wire.

It is shown that the phase transition itself is signaled by a quantized thermal conductance and electrical shot noise power, irrespective of the degree of disorder, in a ring geometry.
