A cold-insertable scanning probe microscope for dry dilution refrigerators with picometer stability and ultra-low electron temperatures
Yizhou Wei, Berthold Jäck
Investigating the microscopic mechanisms of quantum materials requires high-resolution scanning probe techniques, often based on atomic force microscopy (AFM). However, implementin…
Detecting and Distinguishing Majorana Zero Modes with the Scanning Tunneling Microscope
Berthold Jäck, Yonglong Xie, Ali Yazdani
The goal of creating topologically protected qubits using non-Abelian anyons is currently one of the most exciting areas of research in quantum condensed matter physics. Majorana z…
Evidence for a Monolayer Excitonic Insulator
Yanyu Jia, Pengjie Wang, Cheng-Li Chiu +19
The interplay between topology and correlations can generate a variety of quantum phases, many of which remain to be explored. Recent advances have identified monolayer WTe2 as a p…
Observation of backscattering induced by magnetism in a topological edge state
Berthold Jäck, Yonglong Xie, B. Andrei Bernevig +1
The boundary modes of topological insulators are protected by the symmetries of the non-trivial bulk electronic states. Unless these symmetries are broken, they can give rise to no…
Observation of a Majorana zero mode in a topologically protected edge channel
Berthold Jäck, Yonglong Xie, Jian Li +3
Superconducting proximity pairing in helical edge modes, such as those of topological insulators (TI), is predicted to provide a unique platform for realizing Majorana zero modes (…
Spectroscopic signatures of many-body correlations in magic angle twisted bilayer graphene
Yonglong Xie, Biao Lian, Berthold Jäck +6
The discovery of superconducting and insulating states in magic angle twisted bilayer graphene (MATBG) has ignited considerable interest in understanding the nature of electronic i…
