Inhibition of tunnelling and edge state control in polariton topological insulators
Yiqi Zhang, Yaroslav V. Kartashov, Yanpeng Zhang +2
We address the inhibition of tunnelling in polariton condensates confined in a potential landscape created by a honeycomb array of microcavity pillars in the presence of spin-orbit…
Resonant edge-state switching in polariton topological insulators
Yiqi Zhang, Yaroslav V. Kartashov, Yanpeng Zhang +2
Topological insulators are unique devices supporting unidirectional edge states at their interfaces. Due to topological protection, such edge states persist in the presence of diso…
Clusters of cavity solitons bounded by conical radiation
Carles Milian, Yaroslav V. Kartashov, Dmitry V. Skryabin +1
We introduce a new class of self-sustained states, which may exist as single solitons or form multisoliton clusters, in driven passive cylindrical microresonators. Remarkably, such…
Three-dimensional droplets of swirling superfluids
Yaroslav V. Kartashov, Boris A. Malomed, Leticia Tarruell +1
A new method for the creation of 3D solitary topological modes, corresponding to vortical droplets of a two-component dilute superfluid, is presented. We use the recently introduce…
Lieb polariton topological insulators
Chunyan Li, Fangwei Ye, Xianfeng Chen +4
We predict that the interplay between the spin-orbit coupling, stemming from the TE-TM energy splitting, and the Zeeman effect in semiconductor microcavities supporting exci- ton-p…
Cavity solitons in a microring dimer with gain and loss
Carles Milian, Yaroslav V. Kartashov, Dmitry V. Skryabin +1
We address a pair of vertically coupled microring resonators with gain and loss pumped by a single-frequency field. Coupling between microrings results in a twofold splitting of th…
