	abstract = {The single-body and anomalous (pair) correlation functions of Jordan-Wigner fermions in the ground state of a disordered XY chain are calculated. Disorder is introduced into this system as a site-dependent transverse field taken from a uniform distribution of fixed width and within the ferromagnetic phase. Results show that increasing the disorder strength by increasing the distribution width leads to a more rapid decay of correlations within the bulk. The average local transverse magnetization of the spin chain decreases with increasing disorder strength, having greater fluctuations in the middle bulk of the chain.},

	abstract = {The quasi-particle excitation spectrum of an XY spin chain in a random transverse field was calculated by an exact singular value decomposition. The spectrum was found to be robust at small disorder strengths and deep within the paramagnetic phase. For larger disorder strengths, and about the ferromagnetic region, the spectrum deviated further from the quasi-excitation spectrum of the ordered chain. These deviations lead to the disorder-averaged ground state energy E0 to increase with disorder strength, even as the average field strength remains constant.},
