We provide a comprehensive theoretical description of low-energy quantum transport for a Coulomb–Majorana junction, where several helical Luttinger liquid nanowires are coupled to a joint mesoscopic superconductor with finite charging energy. Including the Majorana bound states formed near the ends of superconducting wire parts, we derive and analyze the Keldysh phase action describing non-equilibrium charge transport properties of the junction. The low-energy physics corresponds to a two…

Non-Fermi-liquid manifold in a Majorana device.
TLDR
A nontrivial interplay between multichannel Kondo and resonant Andreev reflection processes, which results in the fixed point manifold, is found.
Kondo physics from quasiparticle poisoning in Majorana devices
Here, we present a theoretical analysis of quasiparticle poisoning in Coulomb-blockaded Majorana fermion systems tunnel-coupled to normal-conducting leads. Taking into account finite-energy…
Charge Fractionalization in the Two-Channel Kondo Effect.
TLDR
It is elucidated that precisely such an unusual effect may occur in the simplest possible non-Fermi liquid, the two-channel Kondo effect, and elementary transport processes of emergent fermions carrying half-integer charge are identified.
Thermodynamics of the topological Kondo model
Topological Kondo Effect
We review recent theoretical progress in the understanding of the topological Kondo effect in Coulomb-blockaded Majorana devices and generalizations thereof. The central ingredient in Majorana…
Emerging Majorana Modes in Junctions of One-Dimensional Spin Systems
The non-local effects induced by Majorana fermions in field theories for condensed matter systems are deeply related to the fermion charge fractionalization discovered by Roman Jackiw in relativistic…

We study multiterminal Majorana and conventional superconducting islands in the vicinity of the charge degeneracy point using bosonization and numerical renormalization group. Both models map to the…
Transport across a system with three p-wave superconducting wires: effects of Majorana modes and interactions
We study the effects of Majorana modes and interactions between electrons on transport in a one-dimensional system with a junction of three p-wave superconductors (SCs) which are connected to normal…
Multichannel Kondo impurity dynamics in a Majorana device.
TLDR
The topological protection of the system raises the perspective to observe multichannel Kondo impurity dynamics in experimentally realistic environments and explores the spin dynamics and its observable ramifications near the low-temperature fixed point.
Tunable spin/charge Kondo effect at a double superconducting island connected to two spinless quantum wires
We propose that a pertinently engineered double superconducting island connected to two spinless one-dimensional conducting leads can work as a tunable (iso)spin Kondo and charge Kondo system, with…

TLDR
A powerful and general approach to describe the coupling of Majorana fermions to external leads, of interacting or noninteracting electrons, is presented, analyzing a highly nontrivial SO(M) Kondo problem arising in topological superconductors with M Majorana-lead couplings, allowing for arbitrary M and for conduction electron interactions.
Majorana single-charge transistor.
TLDR
Coulomb oscillations with universal halving of the finite-temperature peak conductance under strong blockade conditions are found, where the valley conductance mainly comes from elastic cotunneling.
Coulomb-assisted braiding of Majorana fermions in a Josephson junction array
We show how to exchange (braid) Majorana fermions in a network of superconducting nanowires by control over Coulomb interactions rather than tunneling. Even though Majorana fermions are…
Multiterminal Coulomb-Majorana junction.
TLDR
It is shown that a weak finite charging energy of the center island may dramatically affect the low-energy behavior of the system, and the ideally Andreev reflecting fixed point characteristic for infinite capacitance (grounded) devices gets destabilized by interactions.
Majorana fermions and a topological phase transition in semiconductor-superconductor heterostructures.
TLDR
The measurement of the supercurrent through the junction allows one to discern topologically distinct phases and observe a topological phase transition by simply changing the in-plane magnetic field or the gate voltage, which will be a direct demonstration of the existence of Majorana particles.

Helical liquids and Majorana bound states in quantum wires.
TLDR
It is argued that zero-energy Majorana bound states are formed in various situations when such wires are situated in proximity to a conventional s-wave superconductor when the external magnetic field, the superconducting gap, or the chemical potential vary along the wire.
Junctions of three quantum wires
We study a junction of three quantum wires enclosing a magnetic flux. The wires are modelled as single-channel spinless Tomonaga–Luttinger liquids. This is the simplest problem of a quantum junction…

This work predicts a striking nonlocal phase-coherent electron transfer process by virtue of tunneling in and out of a pair of Majorana bound states in a superconductor-quantum-spin-Hall- insulator-magnetic-insulator hybrid system.
