Transport theory for a generic two-arm co-propagating Majorana interferometer with Majorana fermion and edge vortex tunneling
Domenico Giuliano, Andrea Nava, Fabian Hassler +1
Co-propagating chiral Majorana edge modes are predicted to exist in proximity-coupled quantum anomalous Hall systems. They combine the exciting prospects of edge vortices as flying…
Probing proximity-induced superconductivity in bilayer graphene using gate-defined quantum dots
Philipp Schmidt, Mathies Funke, Till Tenger +8
Van der Waals heterostructures offer a direct way of combining two-dimensional (2D) materials with different electronic properties, such as 2D semiconductors, metals, and supercond…
DC Conductance of X-shaped Majorana Interferometer reveals Non-Abelian Anyon Statistics
Domenico Giuliano, Andrea Nava, Reinhold Egger +1
We propose a four-terminal, X-shaped chiral Majorana interferometer with a central floating superconducting island, enabling the direct detection of the non-Abelian statistics of I…
Gate-tunable Josephson diodes in magic-angle twisted bilayer graphene
A. Rothstein, R. J. Dolleman, L. Klebl +8
We report low-temperature measurements of two adjacent, gate-defined Josephson junctions (JJs) in magic-angle twisted bilayer graphene (MATBG) at a moiré filling factor near $ν= -2…
Superbunched radiation of a tunnel junction due to charge quantization
Steven Kim, Fabian Hassler
A chaotic light source is characterized by the fact that many independent emitters radiate photons with a random optical phase. This is similar compared to a tunnel junction where…
Non-Abelian anyon statistics through AC conductance of a Majorana interferometer
Andrea Nava, Reinhold Egger, Fabian Hassler +1
Demonstrating the non-Abelian Ising anyon statistics of Majorana zero modes in a physical platform still represents a major open challenge in physics. We here show that the linear…
Tuning the supercurrent distribution in parallel ballistic graphene Josephson junctions
Philipp Schmidt, Luca Banszerus, Benedikt Frohn +7
We report on a ballistic and fully tunable Josephson junction system consisting of two parallel ribbons of graphene in contact with superconducting MoRe. By electrostatic gating of…
Particle-hole symmetry protects spin-valley blockade in graphene quantum dots
Luca Banszerus, Samuel Möller, Katrin Hecker +6
Particle-hole symmetry plays an important role for the characterization of topological phases in solid-state systems. It is found, for example, in free-fermion systems at half fill…
Observation of the spin-orbit gap in bilayer graphene by one-dimensional ballistic transport
L. Banszerus, B. Frohn, T. Fabian +10
We report on measurements of quantized conductance in gate-defined quantum point contacts in bilayer graphene that allow the observation of subband splittings due to spin-orbit cou…
Weak measurement protocols for Majorana bound state identification
Jan Manousakis, Carolin Wille, Alexander Altland +3
We propose a continuous weak measurement protocol testing the nonlocality of Majorana bound states through current shot noise correlations. The experimental setup contains a topolo…
