Thin-shell instability is one process which can generate entangled structures in astrophysical plasma on collisional (fluid) scales. It is driven by a spatially varying imbalance between the ram pressure of the inflowing upstream plasma and the downstream's thermal pressure at a nonplanar shock. Here we show by means of a particle-in-cell simulation that an analog process can destabilize a thin...

Our model consists of intersecting 2255 brane configuration in M theory, distributed uniformly in the common transverse space and assumed to describe early universe. Equations of state are those following from U duality symmetries and a few standard assumptions. In this model, three spatial directions expand, and seven directions stabilise to constant sizes which depend on certain imbalance amo...

The macroscopic rings observed in the photoluminescence patterns of excitons in coupled quantum wells are explained by a mechanism of carrier imbalance, transport, and recombination. The rings originate from the spatial separation of p and n carriers, and occur at the interface of the p and n domains, where excitons are generated. We explore the states of excitons in the ring over a range of te...
