Tunable superconducting diode effect in a topological nano-SQUID
Ella Nikodem, Jakob Schluck, Max Geier +6
A Josephson diode passes current with zero resistance in one direction but is resistive in the other direction. While such an effect has been observed in several platforms, a large…
Topological Insulator nano-SQUID: Flux-tunable platform for topological superconductivity
Ella Nikodem, Jakob Schluck, Henry F. Legg +5
Many efforts have been made in the past decade to realize topological superconductivity using superconducting proximity effect, but an ideal platform is still lacking. A 3D topolog…
Long-range crossed Andreev reflection in topological insulator nanowires proximitized by a superconductor
Junya Feng, Henry F. Legg, Mahasweta Bagchi +3
Crossed Andreev reflection (CAR) is a nonlocal transport phenomenon that creates/detects Cooper-pair correlations between distant places. It is also the basis of Cooper-pair splitt…
Universal Role of Combined Symmetry for the Protection of the Dirac Cone in Antiferromagnetic Topological Insulators
Asuka Honma, Noriyuki Kabeya, Seigo Souma +13
Antiferromagnetic topological insulators (AF TIs) are predicted to exhibit exotic physical properties such as gigantic optical and topological magnetoelectric responses. While a ke…
Robust gap closing and reopening in topological-insulator Josephson junctions
Jakob Schluck, Ella Nikodem, Anton Montag +4
In the seminal proposal by Fu and Kane, the superconducting proximity effect is used to realize topological superconductivity in the topological surface state (TSS) of a 3D topolog…
Phonon thermal Hall effect in charge-compensated topological insulators
Rohit Sharma, Mahasweta Bagchi, Yongjian Wang +2
From a systematic study of thermal and charge transport in various single crystals of compensated topological insulators we identify the evolution of a large low-temperature therma…
