Abstract :
Modulated charge or spin superstructures of organic quasi-one-dimensional conductors exhibit specific low-energy excitations (LEE) at very low temperatures due to metastable states caused by strong pinning centers. These phase excitations (soliton-like topological defects) demonstrate rich and unexpected properties in a magnetic field, due to their magnetic moments. We discuss mainly on the dynamical aspects related to the non-equilibrium phenomena measured in heat relaxation below 1 K.
