Despite the previously debated d-wave symmetry of the superconducting gap in YNi2B2C as suggested from the interpretation of specific-heat (Cp) data (Nohara et al., 1997), additional mechanisms for the T3 dependence of the electronic part of Cp and its unusual magnetic-field dependence were discussed, including the shrinking of the vortex core radius with increasing field (Nohara et al., 1999). The influence of disorder is discussed in Section 6.2. Measurements of the microwave... 

The theoretical problems raised by the study of CPs will be discussed below as the need arises. Many special properties of CPs are related to their quasi-one-dimensional character for instance, the large influence of disorder, the importance of residual three-dimensional coupling, and the importance of electron-phonon interactions, which, among other consequences, manifests itself in the case of a half-filled band by the occurrence of the Peierls instability. Much of the early theoretical work was concerned with PA, which, as we shall see, is peculiar among presently known CPs by having a degenerate ground state (see Section IV.B). 

A question of great interest is the influence of disorder in the medium on the universality class of dissolved flexible polymers, namely ire the imiversal exponents (1) in this c ise the same as in the pure case The question of how line tr polymers behave in disordered media is not only interesting from a theoretical point of view, but is also relevant for understanding transport properties of polymer chains in porous media, such as an oil recovery, gel electrophoresis, gel permeation chromatography, etc. [14]. 

Iterating the RSRG transformation e.g. for the Wheatstone bridge as described in section 2.4 one effectively operates on a hierarchical lattice, see Fig. 10. One may then investigate the influence of disorder on models defined on such lattices by RSRG methods.

In the first method we employ the first Born approximation for the impurity self-energy [11], This enables us to formulate equations of motion for the full space-dependent Green functions and thus consider the influence of disorder on the non-linear excitations as well [12] (see next Chapter). Furthermore, the replacement of Eq. 3 and Eq. 4 by random (Gaussian) fields...

Various models have been proposed to account for the transport and magnetic properties of these molecular materials [477]. Without going into detail, the influence of disorders on a low-dimensional conductor can be classified in two parts ...
