Boundary-induced Majorana coupling in a planar topological Josephson junction
Hyeongseop Kim, Sang-Jun Choi, H. -S. Sim +1
Understanding environmental effects in a topological Josephson junction is vital for identifying signatures of Majorana modes. We consider a planar Josephson junction formed on the…
Origin of Subharmonic Gap Structure of DC Current-Biased Josephson Junctions
Aritra Lahiri, Sang-Jun Choi, Björn Trauzettel
The current-voltage characteristics of Josephson junctions exhibit a subharmonic gap structure (SGS), denoting jumps at specific voltages. While the prevalent multiple Andreev refl…
AC Josephson Signatures of the Superconducting Higgs Mode
Aritra Lahiri, Sang-Jun Choi, Björn Trauzettel
The Higgs mode in superconductors corresponds to oscillations of the amplitude of the order parameter. While its detection typically entails resonant optical excitation, we present…
