Anomalous low-temperature enhancement of supercurrent in topological-insulator nanoribbon Josephson junctions: evidence for low-energy Andreev bound states
Morteza Kayyalha, Mehdi Kargarian, Aleksandr Kazakov +5
We report anomalous enhancement of the critical current at low temperatures in gate-tunable Josephson junctions made from topological insulator BiSbTeSe nanoribbons with superc…
Gate-tunable supercurrent and multiple Andreev reflections in a superconductor-topological insulator nanoribbon-superconductor hybrid device
Luis A. Jauregui, Morteza Kayyalha, Aleksander Kazakov +3
We report on the observation of gate-tunable proximity-induced superconductivity and multiple Andreev reflections (MAR) in a bulk-insulating BiSbTeSe topological insulator nano…
Parafermion supporting platform based on spin transitions in the fractional quantum Hall effect regime
Tailung Wu, Aleksandr Kazakov, George Simion +7
We propose an experimentally-feasible system based on spin transitions in the fractional quantum Hall effect regime where parafermions, high-order non-abelian excitations, can be p…
Disorder-generated non-Abelions
G. E. Simion, A. Kazakov, L. P. Rokhinson +2
Two classes of topological superconductors and Majorana modes in condensed matter systems are known to date: one, in which impurity disorder strongly suppresses topological superco…
Mesoscopic transport in electrostatically-defined spin-full channels in quantum Hall ferromagnets
Aleksandr Kazakov, George Simion, Yuli Lyanda-Geller +5
In this work we use electrostatic control of quantum Hall ferromagnetic transitions in CdMnTe quantum wells to study electron transport through individual domain walls (DWs) induce…
