We collect experimental and theoretical evidences on existence of microscopic solitons, and their determining role in electronic processes of quasi-1D conductors, see arXiv:0801.3202 and rfs. therein. The recent interest rises from a discovery of the ferroelectric charge ordering in organic conductors, and from nano-scale tunneling experiments in Charge Density Wave (CDW) materials. The charge ordering allows to observe several types of solitons in conductivity and permittivity, and solitons' bound pairs in optics - both in insulating and conducting cases, in a fruitful comparison with conducting polymers. Internal tunneling in CDWs goes through the channel of “amplitude solitons”, which correspond to the long sought quasi-particle - the spinon. The same experiment gives an access to the reversible reconstruction of the junction via spontaneous creation of a lattice of 2π solitons - a grid of dislocations. Individual 2π solitons have been visually captured in recent STM experiments. The resolved subgap tunneling recovers collective quantum processes - instantons, which study provides a tool for the corresponding theory. The theory relies upon a regime of quantum dissipation provided by soft mode emittance in the course of the soliton creation.
