Modified interferometer to measure anyonic braiding statistics
Steven A. Kivelson, Chaitanya Murthy
Existing quantum Hall interferometers measure twice the braiding phase, , of Abelian anyons, i.e. the phase accrued when one quasi-particle encircles another clockwise. We…
Quantum-critical dynamics of a Josephson junction at the topological transition
Vladislav D. Kurilovich, Chaitanya Murthy, Pavel D. Kurilovich +3
We find the admittance of a Josephson junction at or near a topological transition. The dependence of the admittance on frequency and temperature at the critical point is un…
Energy spectrum and current-phase relation of a nanowire Josephson junction close to the topological transition
Chaitanya Murthy, Vladislav D. Kurilovich, Pavel D. Kurilovich +3
A semiconducting nanowire proximitized by an -wave superconductor can be tuned into a topological state by an applied magnetic field. This quantum phase transition is marked by…
Spectral response of Josephson junctions with low-energy quasiparticles
Anna Keselman, Chaitanya Murthy, Bernard van Heck +1
We study nanowire-based Josephson junctions shunted by a capacitor and take into account the presence of low-energy quasiparticle excitations. These are treated by extending conven…
Observation of the 4-periodic Josephson effect in indium arsenide nanowires
Dominique Laroche, Daniël Bouman, David J. van Woerkom +9
Quantum computation by non-Abelian Majorana zero modes (MZMs) offers an approach to achieve fault tolerance by encoding quantum information in the non-local charge parity states of…
