DOI: 10.1093/mnras/stx1073
Abstract: It is known that an embedded massive planet will open a gap in a protoplanetary disc via angular momentum exchange with the disc material. The resulting surface density profile of the disc is investigated for… read more here.

DOI: 10.1093/mnras/sty2475
Abstract: We have performed general relativistic hydrodynamics (GRHD) simulations of 2D discs orbiting around spinning black holes and prone to the Rossby Wave Instability (RWI). We show that the RWI can develop at any location in… read more here.

DOI: 10.1103/physreve.107.034603
Abstract: Granular materials are critical to many natural and industrial processes, yet the chaotic flow behavior makes granular dynamics difficult to understand, model, and control, causing difficulties for natural disaster mitigation as well as scale-up and… read more here.

DOI: 10.1109/tps.2018.2848597
Abstract: The shock wave instability induced when interacting with a small waviness on an interface with plasma was investigated analytically and numerically. The perturbation to the shock was phenomenologically treated assuming this as the consequence of… read more here.

DOI: 10.1126/sciadv.abm5180
Abstract: Quantum materials are notoriously sensitive to their environments, where small perturbations can tip a system toward one of several competing ground states. Graphene hosts a rich assortment of such competing phases, including a bond density… read more here.
