• Abstract: Periodic driving of systems of particles can create crystalline structures in time. Such systems can be used to study solid-state physics phenomena in the time domain. In addition, it is possible to engineer the wave-number band structure of optical systems and to realize photonic time crystals by periodic temporal modulation of the material properties of the electromagnetic wave propagation medium. We introduce here a versatile averaged-permittivity approach which empowers emulating various condensed matter phases in the time dimension in a traveling wave resonator. This is achieved by utilizing temporal modulation of permittivity within a small segment of the resonator and the spatial shape of the segment. The required frequency and depth of the modulation are experimentally achievable, opening a pathway for research into the practical realisation of crystalline structures in time utilising microwave and optical systems.

  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.

We show that the geometry of the ferromagnet plays also an important role, by setting the fundamental frequency of the magnonic resonator.

• Controlled preparation of phases in two-dimensional time crystals [0.0]
  Time crystals constitute periodically driven interacting many-body systems that spontaneously break time translation symmetry. We identify the different phases that characterize the two-dimensional time crystal. These different phases can be mapped to the many-body states existing on a two-dimensional Hubbard lattice model.

We develop a microscopic theory that applies both to moving mirrors with surface profile and atomic array meta-mirrors with perturbed lattice configuration. The proposed space-time dynamical Casimir effect can be interpreted as an induced dynamical asymmetry in the quantum vacuum.

  Entanglement in high-dimensional quantum systems, where one or more degrees of freedom of light are involved, offers increased information capacities and enables new quantum protocols. Here, we demonstrate a functional source of high-dimensional, noise-resilient hyperentangled states encoded in time-frequency and vector-vortex structured modes. We generate highly entangled photon pairs at telecom wavelength that we characterise via two-photon interference and quantum state tomography, achieving near-unity visibilities and fidelities.
