# Project Overview

## Nonlinear Dynamics in Superconducting Networks

### Department(s)

Physics and Astronomy

### Abstract

Two positions are available in the study of superconducting networks in the lab of Ken Segall (see http://departments.colgate.edu/physics/faculty/KenSegall/index.html). Positions will last for eight weeks; starting times are negotiable. The work involves studying the nonlinear and quantum properties of arrays of circuits of Josephson junctions, which are small circuit elements made of superconducting materials. Their nonlinear properties include localization, chaos, vorticity and complexity; quantum properties include quantum coherence and quantum tunneling. We also have an exciting project which uses Josephson junctions as an analog model of neurons in the brain. All students will be involved in cryogenic, data collection and data analysis. In addition, some students will specialize in either computational studies, electronics instrumentation, machine shop work or noise studies when we are not taking data. The sum will be a nice broad exposure to low-temperature physics, applied physics, nonlinear dynamics and computational neuroscience. Students should have taken Physics 232, 233, 334 and 336 to work on these projects. Students interested in pairing this work with Physics 410 in the following year are especially invited to apply.

### Student Qualifications

Students should have taken Physics 232, 233, 334 and 336 to work on these projects, and should be interested in a career in solid state physics, superconductivity, nonlinear dynamics, electrical engineering, experimental physics or computational studies. All students will be involved in cryogenic, data collection and data analysis. In addition, some students will specialize in either computational studies, electronics instrumentation, machine shop work or noise studies when we are not taking data. The sum will be a nice broad exposure to low-temperature physics, applied physics, nonlinear dynamics and computational neuroscience.
