Steady Floquet-Andreev States in Graphene Josephson Junctions

Explore the generation and measurement of steady Floquet-Andreev states in graphene Josephson junctions through a 40-minute lecture by Gil-Ho Lee from PCS Institute for Basic Science. Delve into the paradigm-shifting realm of engineering quantum states through light-matter interaction, focusing on the creation of Floquet-Bloch states in crystals. Discover how continuous microwave application overcomes the limitations of transient Floquet states produced by optical pulses, allowing for direct measurement of spectra using superconducting tunnelling spectroscopy. Examine the quantitative analysis of spectral characteristics while varying superconductor phase differences, temperature, microwave frequency, and power. Gain insights into non-equilibrium quantum states in dissipative condensed matter systems, covering topics such as band engineering, tunneling spectroscopy, Andreev Bound States, and the comparison between Tien-Gordon and Floquet models. Understand the experimental setup for microwave irradiation and its implications for future research in this cutting-edge field of condensed matter physics.
