We find that the amplitude of the Rxx radiation-induced magnetoresistance oscillations in
GaAs/AlGaAs system grows nonlinearly as A / P where A is the amplitude and the exponent
< 1. This strikin...

Using a global equation of state, empirically derived by Luding, we ac-curately model the density profile of a two-dimensional hard sphere system with diameter D and mass m under gravity with a given ...
Asymptotic analysis of stresses near a crack tip in a two dimensional colloidal packing saturated with liquid
Asymptotic analysis of stresses two dimensional colloidal
2010/11/24
The consolidation of colloidal particles in drying colloidal dispersions is in-uenced by various factors such as particle size and shape, and inter-particle potential. The capillary pressure induced b...

We present a derivation of the recently proposed eighth order phase field crystal model [Jaatinen et al. , Phys. Rev. E 80, 031602 (2009)] for the crystallization of a solid from an undercooled melt.
Lifshitz transition in two-dimensional spin-density wave models
Lifshitz transition two-dimensional spin-density wave models
2010/11/23
We argue that both pocket-disappearing and neck-disrupting types of Lifshitz transitions can be
realized in two-dimensional spin-density wave models for underdoped cuprates, and study both
types of ...
