Abstract

One way to experimentally characterize collective oscillations is to measure the magnitude of the steady-state response. In order to examine more dynamic aspects of the behavior, we have measured the hysteresis of the collective response as we vary the collective bifurcation value. Specifically, in our collection of electronic oscillators, we produce a hysteresis by sequentially lowering then raising the bifurcation setting of each oscillator such that the collective bifurcation parameter goes below and above is critical value. The shape of the hysteresis loop exhibits a strong dependence on the rate at which we drive the system through the transition.

We found that the area of the hysteresis loop exhibits a square-root dependence on the driving frequency. This is in contrast to feromagnetic and feroelectric systems, which exhibit power-law frequency dependence with much weaker exponents. 

Skills utilized & developed

• In-Depth Research and Analysis: Understanding the theoretical underpinnings of voltage oscillators, circuit design principles, and Perl programming necessitates rigorous research and analytical skills.

• Experimental Design and Execution: Designing experiments to test the oscillator system's behavior, collecting and analyzing data, and interpreting results are crucial skills for scientific inquiry.

• Technical Writing and Communication: Clearly and concisely conveying complex technical information to a specific audience (e.g., academic peers) requires excellent technical writing skills.

• Problem-Solving and Critical Thinking: Troubleshooting issues with circuit boards, debugging Perl code, and overcoming experimental challenges demand strong problem-solving and critical thinking abilities.

• Time Management and Project Management: Balancing research, circuit design, programming, experimentation, and writing within a thesis deadline requires effective time management and project management skills.

Description

Invited to present annually to the the Academy of Senior Professionals regarding the Nobel Prizes awarded in Physics at the ASPEC Nobel Brunch. This would involve preparing & presenting slides & associated materials, facilitating small group discussions, and answering questions from the attendees.

Skills utilized & developed

• Effective Communication: I have the ability to break down intricate physics concepts into easily understandable terms. This involves clear and concise language, engaging storytelling, and the use of analogies or metaphors.

• Public Speaking: From this experience, I developed confidence, charisma, and the ability to maintain audience engagement.

• Interpersonal Skills: At the ASPEC Nobel Brunch, I answered questions and fostered discussions. This helped develop my strong interpersonal skills, including active listening, empathy, and the ability to build rapport with a diverse audience.

• Critical Thinking and Problem-Solving: Anticipating potential questions and misunderstandings requires critical thinking and problem-solving skills. This involves identifying potential challenges and developing clear and accurate responses.

• Knowledge Synthesis: To effectively communicate these ideas, I had to have a deep understanding of the underlying concepts. I was able to synthesize information from various sources and present it in a coherent and logical manner.
