The Haldane Model with Chiral Edge States using a Synthetic Dimension
Joel Priestley, Gerard Valentí-Rojas, Patrik Öhberg
We explicitly show that the differences, with respect to the appearance of topological phases, between the traditional Haldane model, which utilises a honeycomb lattice structure,…
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…
Bulk Localised Transport States in Infinite and Finite Quasicrystals via Magnetic Aperiodicity
Dean Johnstone, Matthew J. Colbrook, Anne E. B. Nielsen +2
Robust edge transport can occur when particles in crystalline lattices interact with an external magnetic field. This system is well described by Bloch's theorem, with the spectrum…
Gauge transformations and Galilean covariance in nonlinear gauge-coupled quantum fluids
Yvan Buggy, Patrik Öhberg
We investigate certain invariance properties of quantum fluids subject to a nonlinear gauge potential. In particular, we derive the covariant transformation laws for the nonlinear…
