Charge density waves - case not closed

The quasi-onedimensional (Q1D) systems with charge density wave (CDW) ground state have been extensively investigated in the eighties until a “ concensus” on their properties has been reached, or maybe until the high temperature superconductors have been discovered. However, even 20 years later these systems do not end to surprise us that have continued the efforts to study them. Glass transition in the superstructure, random exchange Heisenberg antiferromegnetic chain (REHAC) behaviour of the susceptility, extreme doping sensitivity of the dielectric response and heat capacity, large thermal hysteresis in the dielectric response, large sensitivity of the low temperature conductivity on electric excitations which I will present are only some of many interesting phenomena that we have recently observed.
