Electronic bistability, discontinuous switching and stochasticity in a two-dimensional semiconductor
S. Jana, M. Kravtsov, A. Ermakov +11
Bistability - two stable electronic states under the same bias - underlies switching and memory, but is usually absent in transistors and must be engineered through material means:…
Correlated Insulator Moiré Bolometer
L. Elesin, A. L. Shilov, M. Kravtsov +14
Light incident on an insulator is generally not expected to turn it into a metal without invoking intense ultrafast excitation that leads to transient structural transitions. Here…
Interaction-limited conductivity of twisted bilayer graphene revealed by giant terahertz photoresistance
A. L. Shilov, M. Kravtsov, J. Covey +15
Identifying the microscopic processes that limit conductivity is essential for understanding correlated and quantum-critical states in quantum materials. In twisted bilayer graphen…
Reconstructing Critical Current Density in Josephson Junctions with Phase Non-linearity
A. Kudriashov, R. A. Hovhannisyan, X. Zhou +4
In this Letter, we show that the standard Dynes-Fulton analysis, commonly used to reconstruct the critical current density from interference patterns, breaks down in Josephson junc…
Non-Reciprocal Current-Phase Relation and Superconducting Diode Effect in Topological-Insulator-Based Josephson Junctions
A. Kudriashov, X. Zhou, R. A. Hovhannisyan +11
Josephson junctions (JJ) are essential for superconducting quantum technologies and searches of self-conjugate quasiparticles, pivotal for fault-tolerant quantum computing. Measuri…
