Small fluctuations in epitaxial growth via conservative noise
Small fluctuations epitaxial growth conservative noise
2015/10/16
We study the combined effect of growth (material deposition from above) and nearest-neighbor entropic and force-dipole interactions in a stochastically perturbed system of N line defects (steps) on a ...
Natural and man-made terrestrial electromagnetic noise: an outlook
radio noise background noise
2015/9/2
The terrestrial environment is continuously exposed to electromagnetic radiations which set up a «background»
electromagnetic noise. Within the Non Ionizing Radiation band (NIR), i.e. for f...

Negative Backaction Noise in Interferometric Detection of a Microlever
Negative Backaction Noise Interferometric Detection Microlever
2011/8/11
Abstract: Interferometric detection of mirror displacements is intrinsically limited by laser shot noise. In practice, however, it is often limited by thermal noise. Here we report on an experiment pe...
We show how sign problems in simulations of many-body systems can manifest themselves in the form of heavy-tailed correlator distributions, similar to what is seen in electron propagation through diso...
