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…
Evidence for Isotropic s-Wave Superconductivity in High-Entropy Alloys
Casey K. W. Leung, Xiaofu Zhang, Fabian von Rohr +2
High-entropy alloys (HEA) form through the random arrangement of five or more chemical elements on a crystalline lattice. Despite the significant amount of resulting compositional…
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…
Tunneling spectroscopy of quantum spin liquids
Elio J. König, Mallika T. Randeria, Berthold Jäck
We examine the spectroscopic signatures of tunneling through a Kitaev quantum spin liquid (QSL) barrier in a number of experimentally relevant geometries. We combine contributions…
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…
