• Abstract: One-dimensional Mott insulators can be described using the sine-Gordon model, an integrable quantum field theory that provides the low-energy effective description of several one-dimensional gapped condensed matter systems, including recent realizations with trapped ultra-cold atoms. Employing the theory of Generalized Hydrodynamics, we demonstrate that this model exhibits separation of the transport of topological charge vs. energy. Analysis of the quasiparticle dynamics reveals that the mechanism behind the separation is the reflective scattering between topologically charged kinks/antikinks. The effect of these scattering events is most pronounced at strong coupling and low temperatures, where the distribution of quasiparticles is narrow compared to the reflective scattering amplitude. This effect results in a distinctively shaped "arrowhead" light cone for the topological charge.

  Coupling excitons with quantized radiation has been shown to enable coherent ballistic transport at room temperature inside optical cavities. We develop an efficient mixed-quantum-classical approach to simulate the exciton-polariton quantum dynamics. We find that this enhanced coherence can be traced to a synchronization of phonon fluctuations over multiple layers.

We analyze the impact of the classical transmission and absorption dyadics on the transitions from ingoing to outgoing s-polariton.

  We investigate coherent single-photon transport in a waveguide quantum electrodynamics system containing multiple giant atoms. We find that the non-dipole effects of giant atoms can strongly manipulate several types of collective properties of the output fields. We propose to probe the topological states of a chain of braided giant atoms by using photon scattering spectra.

  We study a variety of topology-related phenomena for phonon-like collective modes in arrays of ultracold polarized dipolar particles. These modes are coherently propagating vibrational excitations, corresponding to oscillations of particles around their equilibrium positions. We demonstrate that such systems offer a distinct and versatile tool to investigate a wide range of topological effects in a single experimental setup.

  In spite of particle losses the quantum entanglement propagation exhibits a ballistic character with propagation speeds related to the differerent quasiparticles that are involved in the dynamics. Our analysis reveals that photon dissipation has a strikingly asymmetric behavior in the two configurations with a much more dramatic role on the holon entanglement propagation than for the doublon case.
