Dynamical Instability of a Rotating Dipolar Bose-Einstein Condensate [PDF]
, 2007 We calculate the hydrodynamic solutions for a dilute Bose-Einstein condensate with long-range dipolar interactions in a rotating, elliptical harmonic trap, and analyse their dynamical stability.

Self-propelled particles with selective attraction-repulsion interaction - From microscopic dynamics to coarse-grained theories [PDF]
, 2013 In this work we derive and analyze coarse-grained descriptions of self-propelled particles with selective attraction-repulsion interaction, where individuals may respond differently to their neighbours depending on their relative state of motion ...

Defect-Mediated Stability: An Effective Hydrodynamic Theory of Spatio-Temporal Chaos
, 1994 Spatiotemporal chaos (STC) exhibited by the Kuramoto-Sivashinsky (KS) equation is investigated analytically and numerically. An effective stochastic equation belonging to the KPZ universality class is constructed by incorporating the chaotic dynamics of ...

Role of hydrodynamic flows in chemically driven droplet division
, 2018 We study the hydrodynamics and shape changes of chemically active droplets. In non-spherical droplets, surface tension generates hydrodynamic flows that drive liquid droplets into a spherical shape.

MHD Stability of ISM Phase Transition Layers I: Magnetic Field Orthogonal to Front [PDF]
, 2009 We consider the scenario of a magnetic field orthogonal to a front separating two media of different temperatures and densities, such as cold and warm interstellar gas, in a 2-D plane-parallel geometry.

Origins of Stability in Automated Underwater Vehicle Systems
IEEE AccessModern underwater vehicles typically operate under the influence of autopilots or control systems. The hydrodynamic design of these vehicles is often undertaken without consideration of how the control system will change the dynamical characteristics of ...
