Selected Publications

Creating a supersolid in one-dimensional Bose mixtures

Author(s)
Ludwig G. Mathey, Ippei Danshita, Charles W. Clark
We identify a one-dimensional supersolid phase in a binary mixture of near-hardcore bosons with weak, local interspecies repulsion. We find realistic conditions

Ultracold Atom Spin Field Effect Transistor

Author(s)
Jay Vaishnav, Julius Ruseckas, Charles W. Clark, Gediminas Juzelunas
We propose a method of constructing cold atom analogs of the spintronic device known as the Datta-Das transistor (DDT), which despite its seminal conceptual
