• profound implications for materials science. Recent studies have shown that spatial correlations of disorder potential can improve superconductivity, prompting a re-evaluation of some theoretical models. This paper explores the influence of disorder correlations on the fundamental properties of

• coupling constant and their impact on the localization length. Our findings offer valuable insights into the role of disorder correlations in shaping the behavior of superconducting materials.

• numerical solutions of microscopic theory equations in low-dimensional samples [19][20]. In most materials, inhomogeneities exhibit a certain structure characterized by long-range spatial correlations. There is a growing recognition that such correlations exert profound alterations of the basic properties

• Discussion GISAXS and XRR We investigate the formation, size and arrangement properties of tantalum nitride nanoparticles within an Al2O3 matrix. GISAXS is especially suitable for this kind of analysis, because it allows for the precise determination of the morphology and spatial correlations of the

Since sequential imaging is subject to lateral drift (lateral movement in between images), an automatic cross

The dynamics of the tethered OML will be discussed in terms of a collective behaviour, with three complementary approaches: a) The DH model addresses spatial
