Hydrodynamic interactions between fluid-dispersed particles are ubiquitous in soft matter and biological systems and they give rise to intriguing collective phenomena. While it was reported that these interactions can facilitate force-driven particle motion over energetic barriers, here we show the opposite effect in a flow-driven system, i.e. that hydrodynamic interactions hinder transport across barriers. We demonstrate this result by combining experiments and theory. In the experiments, we dr...
The study of magnonic thermal Hall effect has recently attracted attention because this effect can be associated with topological phases activated by Dzyaloshinskii-Moriya interaction, which acts similar to a spin-orbital coupling in an electronic system. A topological phase transition may arise when there exist two or more distinct topological phases, and this transition is often revealed by a gap closing. In this work, we consider a ferromagnetic honeycomb lattice described by a Hamiltonian th...
