Topological Gauge Fields and the Composite Particle Duality
Gerard Valentí-Rojas, Aneirin J. Baker, Alessio Celi +1
We introduce topological gauge fields as nontrivial field configurations enforced by topological currents. These fields crucially determine the form of statistical gauge fields tha…
The gauge coupled two-body problem in a ring
Joel Priestley, Gerard Valentí-Rojas, Ewan M. Wright +1
We study the properties of two quantum particles which are confined in a ring. The particles interact via a long-range gauge potential proportional to the distance between the part…
Barriers to Macroscopic Superfluidity and Insulation in a 2D Aubry-André Model
Dean Johnstone, Patrik Öhberg, Callum W. Duncan
We study the ground state phases of interacting bosons in the presence of a 2D Aubry-André potential. By using a a mean-field percolation analysis, we focus on several superlattice…
