Local Response of Topological Order to an External Perturbation
Local Response Topological Order External Perturbation
2016/1/23
We study the behavior of the Re ′nyi entropies for the toric code subject to a variety of different perturbations, by means of 2D density matrix renormalization group and analytical methods. We find t...

Resonance MEMS Bifurcation Perturbation
2015/8/27
We study the dynamics of a thermo-mechanical model for a forced disc shaped, micromechanical limit cycle oscillator.The forcing can be accomplished either parametrically, by modulating the laser beam ...
Environmental perturbation effects on baseline δ15N values and zooplankton trophic flexibility in the southern California Current Ecosystem
Environmental perturbation baseline δ15N values zooplankton trophic flexibility southern California Current Ecosystem
2014/4/2
Nitrogen isotopic compositions of zooplankton in the California Current Ecosystem (CCE) are known to vary over inter-annual scales of climate variability, but the extent to which those changes are dri...
