• Title: The Haldane Model with Chiral Edge States using a Synthetic Dimension
• Authors: Joel Priestley, Gerard Valent\'i-Rojas, and Patrik \"Ohberg
• Abstract summary: We show that the differences between the traditional Haldane model, which utilise a honeycomb lattice structure, and that of the Haldane model imbued onto a brick-wall lattice geometry, are inconsequential. A proposal is then put forward to realise the Haldane model by exploiting the internal degrees of freedom of atoms as a synthetic dimension.

• Abstract: 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, to that of the Haldane model imbued onto a brick-wall lattice geometry, are inconsequential. A proposal is then put forward to realise the Haldane model by exploiting the internal degrees of freedom of atoms as a synthetic dimension. This leads to a convenient platform for the investigation of chiral edge states due to the hard boundaries provided by the hyperfine manifold. We make some cursory comments on the effects of interactions in the system.

• Extended Haldane model -- a modern gateway to topological insulators [0.0]
  We dwell into the Haldane model considering a full parameter space in the presence of spin-orbit interaction. We explain various anomalous quantum Hall effects and quantum spin Hall effects in the extended Haldane model. We demonstrate the concepts of higher order topological insulator phases along with the topological invariants in the anisotropic limit of the extended Haldane model.

• Latent Haldane Models [0.0]
  Latent symmetries, which materialize after performing isospectral reductions, have been shown to be instrumental in revealing novel topological phases in one-dimensional systems. We construct a family of seemingly complicated two-dimensional models that result in energy-dependent Haldane models upon performing an isospectral reduction. We then predict the location of the topological gaps in the aforementioned family of models and construct phase diagrams to determine where the topological phases lie in parameter space.

  We focus on the Kane-Mele model with and without Rashba spin-orbit coupling as a well-known model. We derive explicit expressions for the wave functions, energy dispersion relations, and the spin rotations of the (generic) helical edge states. Our perturbative framework also allows deriving an explicit form for the rotation of the spins of the momentum edge states in the absence of axial spin symmetry.

  We investigate a realistic scenario for the quantum simulation of such systems using cold Rydberg-dressed atoms in optical lattices. We perform a detailed analysis of the phase diagram at half- and incommensurate fillings, in the mean-field approximation. We furthermore study the stability of the phases with respect to temperature within the mean-field approximation.

  We compute the geometric phases acquired in both unitary and dissipative Jaynes-Cummings models. In the dissipative model, the non-unitary effects arise from the outflow of photons through the cavity walls. We show the geometric phase is robust, exhibiting a vanishing correction under a non-unitary evolution.

• Probing chiral edge dynamics and bulk topology of a synthetic Hall system [52.77024349608834]
  Quantum Hall systems are characterized by the quantization of the Hall conductance -- a bulk property rooted in the topological structure of the underlying quantum states. Here, we realize a quantum Hall system using ultracold dysprosium atoms, in a two-dimensional geometry formed by one spatial dimension. We demonstrate that the large number of magnetic sublevels leads to distinct bulk and edge behaviors.
