Feedback Induced Magnetic Phases in Binary Bose-Einstein Condensates

December 7, 2020
Author(s)
Ian B. Spielman, Shangjie Guo, Hilary M. Hurst
Weak measurement in tandem with real-time feedback control is a new route toward engineering novel non-equilibrium quantum matter. Here we develop a theoretical toolbox for quantum feedback control of multicomponent Bose-Einstein condensates (BECs) using

Electron Induced Massive Dynamics of Magnetic Domain Walls

February 4, 2020
Author(s)
Hilary M. Hurst, Victor Galitski, Tero T. Heikkila
We study the dynamics of domain walls (DWs) in a metallic, ferromagnetic nanowire. We develop a Keldysh collective coordinate technique to describe the effect of conduction electrons on rigid magnetic structures. The effective Lagrangian and Langevin

Induced quantum dot probe for materials characterization

April 19, 2019
Author(s)
Hilary M. Hurst, Yun-Pil Shim, Rusko Ruskov, Charles Tahan
We propose a non-destructive means of characterizing a semiconductor wafer via measuring parameters of an induced quantum dot on the material system of interest with a separate probe chip that can also house the measurement circuitry. We show that a single
