• Abstract: Recent measurements of Casimir forces have provided evidence of an intricate modification of quantum fluctuations of the electromagnetic field in complex geometries. Here we introduce a multiple scattering description for Casimir interactions between bodies of arbitrary shape and material composition, admitting an expansion as a sequence of inter- and intra-body wave scatterings. Interactions in complex geometries can be computed within the current experimental resolution from typically a few wave scatterings, notably without any a priori knowledge of the scattering amplitudes of the bodies. Some first applications demonstrate the power of the approach.

  We study theoretically an array of two-level qubits moving relative to a one-dimensional waveguide. When the frequency of this motion approaches twice the qubit resonance frequency, it induces parametric generation of photons and excitation of the qubits. We develop a comprehensive general theoretical framework that incorporates both perturbative diagrammatic techniques and a rigorous master-equation approach.

• Single photon scattering from a chain of giant atoms coupled to a one-dimensional waveguide [0.0]
  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.
