Critical properties of spherically symmetric black hole accretion in Schwarzschild geometry [PDF]

, 2007
The stationary spherically symmetric accretion flow in the Schwarzschild metric has been set up as an autonomous first-order dynamical system, and it has been studied completely analytically.

The role of flow geometry in influencing the stability criteria for low angular momentum axisymmetric black hole accretion

, 2010
Using mathematical formalism borrowed from dynamical systems theory, a complete analytical investigation of the critical behaviour of the stationary flow configuration for the low angular momentum axisymmetric black hole accretion provides valuable ...

Energy harvesting from transverse galloping [PDF]

, 2010
Some elastic bluff bodies under the action of a fluid flow can experience transverse galloping and lose stability if the flow velocity exceeds a critical value.

Entropy flow in near-critical quantum circuits

, 2019
Near-critical quantum circuits are ideal physical systems for asymptotically large-scale quantum computers, because their low energy collective excitations evolve reversibly, effectively isolated from the environment.
