Abstract :
Electron in a quasi one-dimensional NbSe3 whisker crystal form a collective state at low temperature. It is called charge density wave (CDW) state. This article discusses about the coherence properties of the quasi one-dimensionality globally along the entire closed loop which is probed using the polarization vortex.
