Residual bulk viscosity of a disordered 2D electron gas [PDF]
Phys. Rev. B 103, 235305 (2021), 2021 The nonzero bulk viscosity signals breaking of the scale invariance. We demonstrate that a disorder in two-dimensional noninteracting electron gas in a perpendicular magnetic field results in the nonzero disorder-averaged bulk viscosity. We derive analytic expression for the bulk viscosity within the self-consistent Born approximation.

Kelvin-Helmholtz instability and collapse of a twisted magnetic null point with anisotropic viscosity [PDF]
A&A 650, A143 (2021), 2021 Context: Magnetic null points are associated with high-energy coronal phenomena such as solar flares and are often sites of reconnection and particle acceleration. Dynamic twisting of a magnetic null point can generate a Kelvin-Helmholtz instability (KHI) within its fan plane and, under continued twisting, can instigate spine-fan reconnection and an ...

Geophysical Journal of the Royal Astronomical Society, 2010 Direct and indirect estimates of the variation of viscosity with depth in the mantle indicate that a low viscosity layer exists in the upper mantle. A viscosity varying with depth can be used to reconcile the various estimates of relaxation times. If the seismic anelasticity can be used as a guide the average viscosity of the lower mantle is about 10 ...

Viscosity and thermalization [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2004 I solve the Relativistic Navier Stokes Equations assuming boost invariance and rotational symmetry. I compare the resulting numerical solutions for two limiting models of the shear viscosity. In the first model the shear viscosity is made proportional to the temperature.
