Abstract: Atomtronics, an ultracold atom analog of electronics, provides a practical pathway for utilizing the quantum character of ultracold atoms in a variety of compelling applications involving sensing and signal processing. The atomtronic transistor, for example, is an analog of the electronic transistor that is exceedingly useful for creating amplifiers, oscillators, switches and so on. The understanding of atomtronic circuitry takes us to fundamental depths of field theory applied to a very practical domain. Along with many familiar parallels to Maxwell’s equations and electromagnetics, the physics of atomtronics is also surprising, sometimes seemingly absurd. I will take some time to draw the connection between fundamental physics starting with CU’s Nobel-recognized accomplishments in Bose-Einstein Condensation and the impact on and by the very practical technology developed by CU spinoff ColdQuanta (now Infleqtion), recently honored to have one of Time’s 2022 Invention of the year award for its quantum matter machine “Albert” that is used for developing atomtronic circuits.


Coffee, tea and cookies will be available in G1B31 (across from G1B20) from 3:30 - 3:50 p.m.

Physics Colloquia are held Wednesdays at 4:00 p.m. in the JILA Auditorium.
