Phase-channel dynamics reveal the role of impurities and screening in a quasi-one-dimensional charge-density wave system

M. D. Thomson, K. Rabia, F. Meng +3

We investigate the low-energy phase excitations of the quasi-one-dimensional charge density wave (CDW) in ${\mathrm{K}}_{0.3}\mathrm{Mo}{\mathrm{O}}_3$, by direct probing of infrared-a…
