Ion thermal effects on E-region instabilities: 2D kinetic simulations
E-region electrojet Ionospheric irregularities Plasma instabilities
2017/3/22
Radars frequently receive strong returns from naturally occurring plasma density irregularities centered around
100 km altitude in the atmosphere. These E-region ionospheric irregularities occur when...
Plasma instabilities in meteor trails: 2-D simulation studies
2-D simulation studies Plasma instabilities
2017/3/22
Field-aligned plasma density irregularities detected as nonspecular echoes by radars
with large aperture-power products indicate the presence of plasma turbulence within
meteor trails. This paper pr...

Period fissioning and other instabilities of stressed elastic membranes
Under elastic membrane the shape of stretching two dimensional parameter space
2014/12/19
We study the shapes of elastic membranes under the simultaneous exertion of tensile and compressive forces when the translational symmetry along the tension direction is broken. We predict a multitude...
Reactive-infiltration instabilities in rocks. Fracture dissolution
Reactive-infiltration instabilities rocks Fracture dissolution Fluid Dynamics
2012/4/19
A reactive fluid dissolving the surface of a uniform fracture will trigger an instability in the dissolution front, leading to spontaneous formation of pronounced well-spaced channels in the surroundi...
Chemo-mechanical instabilities in polarizable active layers
Chemo-mechanical instabilities polarizable active layers Biological Physics
2012/4/19
We formulate and explore a generic continuum model of a polarizable active layer with neo-Hookean elasticity and chemo-mechanical interactions. Homogeneous solutions of the model equations exhibit a s...
On the connection between the magneto-elliptic and magneto-rotational instabilities
On the connection magneto-elliptic magneto-rotational instabilities
2012/2/23
It has been recently suggested that the magneto-rotational instability (MRI) is a limiting case of the magneto-elliptic instability (MEI). This limit is obtained for horizontal modes in the presence o...

Thermodynamics Instabilities Anisotropic Plasma
2011/7/21
We extend our analysis of a IIB supergravity solution dual to a spatially anisotropic finite-temperature N=4 super Yang-Mills plasma. The solution is static, possesses an anisotropic horizon, and is c...
Turing instabilities in a mathematical model for signaling networks
Turing instability non-local reaction-diffusion system signaling molecules
2011/8/30
Abstract: GTPase molecules are important regulators in cells that continuously run through an activation/deactivation and membrane-attachment/membrane-detachment cycle. Activated GTPase is able to loc...
Mechanism of ferroelectric instabilities in non d^0 perovskites: LaCrO_3 versus CaMnO_3
Mechanism of ferroelectric instabilities non d^0 perovskites
2010/11/24
The incompatibility of partial d occupation on the perovskite B-site with the standard charge
transfer mechanism for ferroelectricity has been a central paradigm in multiferroics research. Nev-erthel...

Detection of spin injection double quantum dot: Violation nuclear polarization instabilities
2010/11/19
In mesoscopic systems with spin-orbit coupling, spin-injection into quantum dots at zero magnetic eld is expected under a wide range of conditions. However, up to now, a viable approach for experimen...

Sun oscillations Physical Data and Processes magnetic fields MHD—waves
2010/11/11
Quasi-biennial oscillations (QBO) are frequently observed in the solar activity indices. However, no clear physical mechanism for the observed variations has been suggested so far. Here we study the s...
