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…
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…
Anomalous terahertz photoconductivity caused by the superballistic flow of hydrodynamic electrons in graphene
M. Kravtsov, A. L. Shilov, Y. Yang +18
Light incident upon materials can induce changes in their electrical conductivity, a phenomenon referred to as photoresistance. In semiconductors, the photoresistance is negative,…
Probing polarization response of monolayer cell cultures with photon entanglement
L. Zhang, V. R. Besaga, P. Rühl +4
This study addresses the critical need for high signal-to-noise ratio in optical detection methods for biological sample discrimination under low-photon-flux conditions to ensure a…
