Orientation dependence of the elastic instability on strained SiGe films
, 2010 At low strain, SiGe films on Si substrates undergo a continuous nucleationless morphological evolution known as the Asaro-Tiller-Grinfeld instability. We demonstrate experimentally that this instability develops on Si(001) but not on Si(111) even after ...

Hydrodynamic fingering instability of driven wetting films: hindrance by diffusion [PDF]
, 1990 Recent experimental and theoretical efforts have revealed the existence of a fingering instability at the moving front of thin liquid films forced to spread under gravitational, rotational or surface shear stresses, as for example by using the Marangoni ...

Inhomogeneous instability patterns in polyacrylamide hydrogel bilayers
Mechanical Engineering JournalInstability-induced patterns with spatially varying dimensions and geometric shapes, or inhomogeneous instability patterns, are ubiquitous in biological structures and have attracted much interest in both fundamental research and engineering applications.

Regular black holes without mass inflation instability
Journal of High Energy Physics, 2022 Generic models of regular black holes have separate outer and inner horizons, both with nonzero surface gravity. It has been shown that a nonzero inner horizon surface gravity results in exponential instability at the inner horizon controlled by this ...

Mounding instability and incoherent surface kinetics [PDF]
Physical Review E, 2003 Mounding instability in a conserved growth from vapor is analysed within the framework of adatom kinetics on the growing surface. The analysis shows that depending on the local structure on the surface, kinetics of adatoms may vary, leading to disjoint regions in the sense of a continuum description. This is manifested particularly under the conditions

Instabilities during the evaporation of a film: non glassy polymer + volatile solvent
, 2001 We consider solutions where the surface tension of the solvent is smaller than the surface tension of the polymer. In an evaporating film, a plume of solvent rich fluid, then induces a local depression in surface tension, and the surface forces tend to ...

On effect of surface tension in the Rayleigh–Taylor problem of stratified viscoelastic fluids
Boundary Value Problems, 2019 In this article, we investigate the effect of surface tension in the Rayleigh–Taylor (RT) problem of stratified incompressible viscoelastic fluids. We prove that there exists an unstable solution to the linearized stratified RT problem with a largest ...

Low density instability in a nuclear Fermi liquid drop
, 1998 The instability of a Fermi-liquid drop with respect to bulk density distortions is considered. It is shown that the presence of the surface strongly reduces the growth rate of the bulk instability of the finite Fermi-liquid drop because of the anomalous ...

Fermi surface instabilities at finite temperature [PDF]
The European Physical Journal B, 2013 We present a new method to detect Fermi surface instabilities for interacting systems at finite temperature. We first apply it to a list of cases studied previously, recovering already known results in a very economic way, and obtaining most of the information on the phase diagram analytically.

Metastability of a granular surface in a spinning bucket
, 1998 The surface shape of a spinning bucket of granular material is studied using a continuum model of surface flow developed by Bouchaud et al. and Mehta et al. An experimentally observed central subcritical region is reproduced by the model. The subcritical
