    Abstract: Transition metal dichalcogenides (TMDCs) have attracted much interest for their potential applications in opto-electronic, spintronics and valleytronics devices. Direct determination of the electronic- and surface structure of TMDCs is crucial to the full understanding of their distinctive properties. In particular, like other atomically thin materials, the interactions with substrate impact the surface structure and morphology of TMDCs, and as a result, their structural and physical properties can be affected.

    Abstract: In strongly correlated electron materials (CEMs), the delicate interplay between spin, charge, and lattice degrees of freedom often leads to extremely rich phase diagrams exhibiting intrinsic phase inhomogeneities. The key to understand such complexities usually lies in the characterization and control of these materials at fundamental energy, time and length scales.

    Abstract: The electronic nematic state has become one of the hottest topics in the research of quantum materials. The most intriguing part of this phase is the correlation effects: electrons in the system are correlated and organize themselves into a unidirectional phase – a quantum version of liquid crystals, with only rotation symmetry broken. Although proposed decades ago, this phase was observed only recently in iron superconductors, cuprates, heavy fermion, and several other systems.

    Abstract: Generation of entangled photons in nonlinear media constitutes a basic building block of modern photonic quantum technology. Current optical materials are severely limited in their ability to produce three or more entangled photons in a single event due to weak nonlinearities and challenges in achieving phase-matching. Photon losses in materials and devices further limit performance. We are developing integrated nanoscale TiO2 waveguides to enable efficient generation of entangled photon triplets using third-order spontaneous parametric down-conversion.

    Abstract: Two-dimensional layered materials such as graphene, h-BN and transition metal dichalcogenides, by the virtue of their unique properties provide immense opportunities not only to explore fundamental physics but also to solve critical technological problems. Transition metal dichalcogenides (TMDs), such as MoS2, WSe2, MoSe2 and many others belong to this class of materials, which we are exploring.
