Ultracold Quantum Matter Theory
Ultracold quantum matter theory
The theory group led by Russell Bisset explores novel phases of matter using ultracold gases. At nanokelvin temperatures, gases can become superfluid, flowing without resistance. These exotic states provide a unique window into the quantum world, enabling direct observations of macroscopic quantum phenomena in highly controllable settings. Our research focuses on the theoretical modeling of ultracold quantum gases and the investigation of their incredibly rich phenomena.
Our research interests include:
- Supersolidity: Phases of matter that simultaneously exhibit both solid and superfluid properties, recently realized in dipolar Bose-Einstein condensates.
- Quantum droplets: Quantum gases with nontrivial interactions can form dilute, self-bound liquids stabilized by quantum fluctuations.
- Quasiparticles and topological defects: The novel phases of quantum gasses support a rich array of excitations, including Nambu-Goldstone modes, Higgs excitations, phonons, rotons, solitons and quantized vortices.

Ultracold Atoms and Quantum Gases
Russell Bisset is a theoretical physicist specializing in ultracold quantum gases, which offer platforms with a nearly endless level of control and flexibility. His research focuses on exploring novel quantum phases and uncovering their exciting properties. In addition to purely theoretical work, Russell also collaborates with experimentalists, achieving, among other milestones, the first dipolar supersolid states, 2D supersolids, and quantized vortices in dipolar condensates.
