Lessons from Transforming Second-Year Honors Physics Lab
Danny Doucette, Brian D'Urso, Chandralekha Singh
New technology like the Arduino microcontroller platform presents an opportunity to transform Beyond the First Year (BFY) physics labs to better prepare physics students for work i…
Active Optical Table Tilt Stabilization
Charles W. Lewandowski, Tyler D. Knowles, Zachariah B. Etienne +1
We show that a simple modification to an optical table with pneumatic vibration isolation can be used to actively reduce the long term drift in the tilt of the table by nearly a fa…
High sensitivity accelerometry with a feedback-cooled magnetically levitated microsphere
Charles W. Lewandowski, Tyler D. Knowles, Zachariah B. Etienne +1
We show that a magnetically levitated microsphere in high vacuum can be used as an accelerometer by comparing its response to that of a commercially available geophone. This system…
Reconfigurable edge-state engineering in graphene using LaAlO/SrTiO nanostructures
Jianan Li, Qing Guo, Lu Chen +9
The properties of graphene depend sensitively on doping with respect to the charge-neutrality point (CNP). Tuning the CNP usually requires electrical gating or chemical doping. Her…
Cooling the Motion of a Silica Microsphere in a Magneto-Gravitational Trap in Ultra-High Vacuum
Bradley R. Slezak, Charles W. Lewandowski, Jen-Feng Hsu +1
Levitated optomechanical systems, and particularly particles trapped in vacuum, provide unique platforms for studying the mechanical behavior of objects well-isolated from their en…
Graphene-Complex-oxide Nanoscale Device Concepts
Giriraj Jnawali, Hyungwoo Lee, Jung-Woo Lee +9
The integration of graphene with complex-oxide heterostructures such as LaAlO/SrTiO offers the opportunity to combine the multifunctional properties of an oxide interface w…
