133
134  <p>We study the theory of quantum fluids: many-body systems where waves, particles, vortices, dissipation, and entanglement meet.</p>
135
136<p>Based in the <a href="http://physics.otago.ac.nz">Physics Department</a> at the <a href="https://www.otago.ac.nz/">University of Otago</a>, our group develops theoretical and computational methods for ultracold atoms, quantum fluids of light, and open quantum systems. We work closely with experiment, using quantum field theory, quantum optics, and numerical modelling to understand how collective quantum behaviour emerges, evolves, and breaks down.</p>
137
138<p>Our current research spans quantum turbulence, finite-temperature superfluid dynamics, dissipative quantum systems, and light–matter platforms for exploring many-body physics.

Line numbers count LF bytes from the start of the resource, as the search results do. Vendor segments are library code the classifier recognised; they are stored but not indexed. Bytes are shown as Latin1 characters, one per byte.
