Extracting the anyonic exchange phase from co-tunneling through an open quantum dot
Felix Puster, Matthias Thamm, Bernd Rosenow
The elementary excitations of fractional quantum Hall states obey anyonic statistics, described by an exchange phase intermediate between the bosonic and fermionic values. We s…
Anyon Exchange Phase from Antidot Interferometry
Matthias Thamm, Felix Puster, Bernd Rosenow
Quasiparticles in fractional quantum Hall systems are anyons, carrying a fraction of the electron charge. Exchanging two of them gives rise to a fractional exchange phase. While th…
Extracting the Anyonic Exchange Phase from Hanbury Brown-Twiss Correlations
Felix Puster, Matthias Thamm, Bernd Rosenow
In recent years, interferometry experiments in fractional quantum Hall devices have reported signatures of a fractional braiding phase for quasiparticles. It was noted, however, th…
Edge Reconstruction in a Quantum Spin Hall Insulator
Rahul Soni, Matthias Thamm, Gonzalo Alvarez +2
We study interaction-driven edge reconstruction in a quantum spin Hall insulator described by the Bernevig-Hughes-Zhang model with Kanamori-Hubbard interactions using the real-spac…
Finite Soliton Width Matters: Investigating Non-equilibrium Exchange Phases of Anyons
Matthias Thamm, Bernd Rosenow
Unlike bosons and fermions, quasi-particles in two-dimensional quantum systems, known as anyons, exhibit statistical exchange phases that range between and . In fractional q…
Topological gap protocol based machine learning optimization of Majorana hybrid wires
Matthias Thamm, Bernd Rosenow
Majorana zero modes in superconductor-nanowire hybrid structures are a promising candidate for topologically protected qubits with the potential to be used in scalable structures.…
Machine learning optimization of Majorana hybrid nanowires
Matthias Thamm, Bernd Rosenow
As the complexity of quantum systems such as quantum bit arrays increases, efforts to automate expensive tuning are increasingly worthwhile. We investigate machine learning based t…
Transmission Amplitude through a Coulomb blockaded Majorana Wire
Matthias Thamm, Bernd Rosenow
We study coherent electronic transport through a Coulomb blockaded superconducting Rashba wire in the co-tunneling regime between conductance resonances. By varying an external Zee…
