\nAbstract: \;Q uantum interference phenomena in superconductors\, such as Josephson inter ference and Little-Parks oscillations\, serve as powerful probes of phase coherence\, symmetry breaking and vortex dynamics. The resulting interfere nce patterns can encode rich information about topological states\, magnet ism\, and other intrinsic properties of materials placed in close proximit y to a superconducting system or the superconductor itself.
\nIn this talk\, I will present three examples illus trating how superconducting interference can be used to uncover novel phys ical phenomena in quantum materials. In one example\, spin-polarized super currents are engineered through the superconducting proximity effect\, rev ealing spatially localized topological edge states via Josephson interfere nce patterns [1]. In another\, an orbital-magnetic Josephson junction and a zero-field superconducting diode effect are realized in fully gate-defin ed magic-angle twisted bilayer graphene [2]. In the last part\, I will dis cuss how superconducting interference provides new insights into two-dimen sional superconductors within the superconducting fluctuation regime [3].< /p>\n

\nShort bio: Dr Elisa Shuoying Yang recei ved her Bachelor’s degree from Bryn Mawr College in 2014 and her Master ’s degree from Columbia University in 2016. In 2020\, she obtained her P h.D. in condensed matter physics from the Max Planck Institute of Microstr ucture Physics in Germany. Subsequently\, she moved to Spain and conducted postdoctoral research at ICFO and ICN2. Since November 2023\, she has joi ned the Department of Physics at the Southern University of Science and Te chnology as an assistant professor. Her current interests involve around t opological quantum states of matter\, magnetism\, unconventional supercond uctivity\, and the interactions among them. By utilizing various forms of van der Waals materials\, stacking order\, and novel designs\, her group e ngineers and probes exotic quantum states of matter by low-temperature qua ntum transport techniques. \;
