Spectral Statistics in Chiral-Orthogonal Disordered Systems
S. N. Evangelou, D. E. Katsanos
We describe the singularities in the averaged density of states and the corresponding statistics of the energy levels in two- (2D) and three-dimensional (3D) chiral symmetric and t…
Power-law Localization in 2D, 3D with Off-diagonal Disorder
Shi-Jie Xiong, S. N. Evangelou
We describe non-conventional localization of the midband E=0 state in square and cubic finite bipartite lattices with off-diagonal disorder by solving numerically the linear equati…
Localization Transition in Multilayered Disordered Systems
S. N. Evangelou, Shi-Jie Xiong, P. Markov +1
The Anderson delocalization-localization transition is studied in multilayered systems with randomly placed interlayer bonds of density and strength . In the absence of diag…
First Order Metal-Insulator Transition in Two-dimensional Disordered Systems
Shie-Jie Xiong, G. N. Katomeris, S. N. Evangelou
In the absence of magnetic field or spin-orbit coupling the one-parameter scaling theory predicts localization of all states in two-dimensional (2D) disordered systems, for any amo…
Anisotropic Quantum Transport in Layered High-- Cuprates
S. N. Evangelou, Shi-Jie Xiong, Ding-Yu Xing +1
A random lattice model with dilute interlayer bonds of density is proposed to describe the underdoped high-- cuprates. We show analytically via an appropriate perturbation…
Superconductivity-Induced Anderson Localisation
D. E. Katsanos, S. N. Evangelou, C. J. Lambert
We have studied the effect of a random superconducting order parameter on the localization of quasi-particles, by numerical finite size scaling of the Bogoliubov-de Gennes tight-bi…
Sparse random matrix configurations for two or three interacting electrons in a random potential
Shi-Jie Xiong, S. N. Evangelou
We investigate the random matrix configurations for two or three interacting electrons in one-dimensional disordered systems. In a suitable non-interacting localized electron basis…
