In 1990, a seminar was initiated for QMC (formerly CNAM/CSR) graduate students in order to present their research to the other students, postdocs, and faculty in the Center. In addition to fostering a rich, collaborative environment in which students learn about the breadth and scope of research being done in QMC, the idea of this series is to teach several crucial skills to our students:
1) How to present their research in a clear and time-efficient way to an audience that was not expert in their area of research;
2) How to best answer questions during their presentations;
3) How to ask good questions when in an audience (or interview), in particular about research beyond their own narrow PhD topic.
In this seminar, students submit formalized feedback to each weekly presenter, providing informative information about presentation style, research content and tips for improvement.

Abstract:
Radio frequency Superconducting Quantum Interference Device (rf SQUID) has been established as a viable building block for microwave frequency metamaterials [1,2]. The rf SQUID resonance is tunable under applied dc flux, with upper-frequency range scaling as1+rf . Our previous design restricted the parameter rf below unity to avoid hysteresis, thus limited the resonance range. We have built new arrays of rf SQUID meta-atoms in the hysteretic regime (rf >1) to explore their interesting properties with the ultimate goal of extending the resonance frequency tunability. Much theoretical work has predicted chaotic dynamics and chimera states in such systems. Results from microwave transmission measurements showing signs of these phenomena will be reported. We will also discuss the future work of observing chimera in laser scanning microscopy [3]. This work is supported by DOE through grant # DESC0018788.
