Amplitude-mode dynamics of polariton condensates
(2011)We study the stability of collective amplitude excitations in nonequilibrium polariton condensates. These excitations correspond to renormalized upper polaritons and to the collective amplitude modes of atomic gases and ... -
Demonstration and interpretation of "scutoid" cells formed in a quasi-2D soap froth
(2018)Recently a novel type of epithelial cell has been discovered and dubbed the ‘scutoid’. It is induced by curvature of the bounding surfaces. We show by simulations and experiments that such cells are to be found in a dry ... -
A simple experimental system to illustrate the nonlinear properties of a linear chain under compression.
(2020)A linear chain of spheres confined by a transverse harmonic potential experiences localized buckling under compression. We present simple experiments using gas bubbles in a liquid-filled tube to demonstrate this phenomenon. ... -
Theoretical analysis of the performance of a foam fractionation column
(2014)A model system for theory and experiment which is relevant to foam fractionation consists of a column of foam moving through an inverted U-tube between two pools of surfactant solution. The foam drainage equation is used ... -
Using Your Beam Efficiently: Reducing Electron Dose in the STEM via Flyback Compensation
(2022)In the scanning transmission electron microscope, fast-scanning and frame-averaging are two widely used approaches for reducing electron-beam damage and increasing image signal noise ratio which require no additional ...
