Аннотация:We show that the charge density wave (CDW) ground state below the Peierls transition temperature TCDW ofrare-earth tritellurides is not at its equilibrium value, but depends on the time where the system was kept at a fixedtemperature below TCDW . This ergodicity breaking is revealed by the increase of the threshold electric field forCDW sliding which depends exponentially on time. We tentatively explain this behavior by the reorganizationof the oligomeric (Tex )2− sequence forming the CDW modulation.
