Charge density wave transition probed by interferometric dilatometry

We report on new method of measuring sample length, based on interferometric measurements. Motivation for exploring this technique is to study the coupling between charge density wave (CDW) and underlying crystal lattice. Several papers report the dilatation measurements on CDW systems which can be related to CDW transition [1], CDW hysteresis [2], as well as low Temperature glass transition [3]. Coupling with lattice is also evident from calorimetric measurements at glass transition temperature [4]. Our aim is to apply this method to other CDW systems as well as other systems with electronic superstructure.
