Inspired by the long carrier lifetimes (electron-electron and electron-phonon) in graphene and other 2D materials we have designed and developed computational strategies to integrate designer 2D metals, starting with Argentene and Cuphene. Cuphene and Argentene are new 2D materials that consist of a single atomic layer of silver/copper. These 2D metals have the potential to exhibit 10 times the conductance of optimally-doped graphene, and 50 times that of conventional 3D copper lines scaled to 1 nm dimensions. Achieving high carrier density and mobility in a 2D material like Cuphene or Argentene, will be transformative for atomic-scale photonics (extremely relevant in next generation architectures) and optical elements such as monolayer waveguides, sensors, and emission control layers. Realizing the potential of 2D metals, truly monolayer metals, requires an understanding of single-crystalline atomic layers of metals. Further, we identify suitable combinations of substrates and metals, with computational screening of thermodynamic stability. In addition to 3D crystalline substrates, we also investigate the feasibility of metal monolayers on existing 2D materials in order to facilitate their incorporation into van der Waals stacks. This is an example of carrier lifetime-driven approach to quantum materials where we expect time-domain properties of a monolayer to be distinct from few-layer and bulk. Taking this work further, we will discuss lifetimes and scattering in new classes of quantum materials including Weyl semimetals (WSMs). The field of topological materials with strong electron-electron interactions is well established and has been the subject of intense research over the past few decades. In parallel, the field of photonics has made tremendous progress in connecting spatio-temporal measurements of new quantum materials, including 2D plasmonics and Moir'{e} structure localized potentials, to theoretical predictions. The study of the interplay between topological properties, quantum optics and plasmonic interactions in these materials has only very recently started to receive attention. Experimental demonstrations in Type II Dirac/Weyl semimetals, materials where electrons effectively interact as massless relativistic particles (Weyl fermions) and in 3D the conduction and valence bands touch at isolated points, have shown evidence of a viscous electronic transport regime similar to hydrodynamic electron flow observed at charge neutrality in graphene. In this regime, electron-electron scattering dominates over impurity scattering and other momentum-relaxing processes so that momentum is quasi-conserved and electron flow can be described using the formalism of hydrodynamics. This leads to a variety of surprising behaviors such as breakdown of the Wiedemann-Franz law, appearance of electron vortices, and tunable viscosity via magnetic field in a Weyl semimetal.

With recent advances in nanophotonics, metasurfaces based on nano-resonators have facilitated novel types of optical devices. In particular, the interplay between different degrees of freedom, involving polarization and spatial modes, boosted classical polarization measurements and imaging applications. However, the use of metasurfaces for measuring the quantum states of light remains largely unexplored. Conventionally, the task of quantum state tomography is realized with several bulk optical elements, which need to be reconfigured multiple times. Such setups can suffer from decoherence, and there is a fundamental and practical interest in developing integrated solutions for measurement of multi-photon quantum states. We present a new concept and the first experimental realization of all-dielectric metasurfaces with no tuneable elements for imaging-based reconstruction of the full quantum state of entangled photons. Most prominently, we implement multi-photon interferometric measurements on a sub-wavelength thin optical element, which delivers ultimate miniaturization and extremely high robustness. Specifically, we realize a highly transparent all-dielectric metasurface, which spatially splits different components of quantum-polarization states. Then, a simple one-shot measurement of correlations with polarization-insensitive on-off click detectors enables complete reconstruction of multi-photon density matrices with high precision. In our experiment, we prepare sets of polarization states and reconstruct their density matrices with a high fidelity of over 99% for single photon states and above 95% for two-photon states. Our work provides a fundamental advance in the imaging of quantum states, where multi-photon quantum interference takes place at sub-wavelength scale.
