Two-dimensional transition-metal dichalcogenides (TMDs) are atomically thin semiconductors that exhibit strong excitonic effects, high optical nonlinearities, and valley-contrasting optical selection rules. In monolayer TMDs, circularly polarized light selectively addresses the inequivalent K and K′ valleys, enabling optical initialization and readout of the valley degree of freedom. These...

Binary group IV-VI chalcogenides, like SnTe, GeTe and SnSe, are of great scientific interest due to their diverse possible applications ranging from thermoelectrica to phase change memory. As possible origin of these remarkable properties, the interatomic bonding is center of an ongoing scientific debate. All binary group IV-VI compounds exhibit an average number of five valence electrons per...

We present a joint experimental and theoretical study of a ratchet implemented in arrays of evanescently coupled plasmonic waveguides with tailored losses. In this setup the time-periodic dissipation is the only active mechanism and notably, we find better rectified transport and lower losses in the transmitted signal with increased local dissipation. Using Floquet theory, we uncover a driving...
