Abstract: Topological states emerge at the boundary of solids as a consequence of the nontrivial topology of the bulk. Recently, theory predicts a topological edge state on single layer transition metal dichalcogenides with 1T’ structure. However,… read more here.

DOI: 10.1103/physrevb.100.184511
Abstract: Most topological superconductors known to date suffer from low transition temperatures (Tc) and/or high fragility to disorder and dopant levels, which is hampering the progress in this promising field. Here, utilizing a combination of angle-resolved… read more here.

DOI: 10.1364/ol.461485
Abstract: We report on the experimental observation of the topological Anderson phase in one-dimensional quasi-periodical waveguide arrays produced by femtosecond laser writing. The evanescently coupled waveguides are with alternating coupling constants, constructing photonic lattices analogous to… read more here.

DOI: 10.1364/ome.414517
Abstract: We have designed honeycomb lattices for microwave photons with a frequency imbalance between the two sites in the unit cell. This imbalance is the equivalent of a mass term that breaks the lattice inversion symmetry.… read more here.
