Recent views on solitons in density waves

Recent experiments on coherent interlayer tunneling in Charge Density Wave materials can be interpreted as direct observation of microscopic solitons in single electronic processes. Tunneling of electrons can go through the channel of solitons which are more favorable quantum particles than electrons. These solitons might correspond to the well searched special quasiparticle - the spinon. We shall summarize the necessary elements of theory in conjunction with both new experiments and earlier available data.
