The primary goal of this treatise is to introduce a new kind of generalized closed sets termed as Lgfs-closed sets in the light of fuzzy soft local function in a mixed fuzzy soft ideal topological space. Wealso define the notion of fuzzy soft ∗-separated set. In addition, we procure the idea of fuzzy soft regularity,normality and fuzzy soft compactness. We also study their behavior in terms of Lgfs-closed sets.

Motivated by recent scanning tuneling microscopy (STM) experiments on Bi 2 Sr 2 CaCu 2 O 8 + δ [J. E. Hoffman et al., Science 295, 466 (2002); C. Howald et al., cond-mat/0201546 (unpublished); J. E. Hoffman et al., Science 297, 1149 (2002): K. McElroy et al. (unpublished); C. Howald et al., cond-mat/0208442 (unpublished)], we study the effects of weak translational symmetry breaking on the quasiparticle spectrum of a d-wave superconductor. We develop a general formalism to discuss periodic charge order, as well as quasiparticle scattering off localized defects. We argue that the STM experiments in Bi 2 Sr 2 CaCu 2 O 8 + δ cannot be explained using a simple charge density wave order parameter, but are consistent with the presence of a periodic modulation in the electron hopping or pairing amplitude. We review the effects of randomness and pinning of the charge order and compare it to the impurity scattering of quasiparticles. We also discuss implications of weak translational symmetry breaking for angle resolved photoemission spectroscopy experiments.
