Critical level-statistics for weakly disordered graphene
H. Amanatidis, I. Kleftogiannis, D. E. Katsanos +1
In two dimensions chaotic level-statistics is expected for massless Dirac fermions in the presence of disorder. For weakly disordered graphene flakes with zigzag edges the obtained…
Quantum Walks on a Random Environment
Yue Yin, D. E. Katsanos, S. N. Evangelou
Quantum walks are considered in a one-dimensional random medium characterized by static or dynamic disorder. Quantum interference for static disorder can lead to Anderson localizat…
Quantum correlations from Brownian diffusion of chaotic level-spacings
S. N. Evangelou, D. E. Katsanos
Quantum chaos is linked to Brownian diffusion of the underlying quantum energy level-spacing sequences. The level-spacings viewed as functions of their order execute random walks w…
Fractal Noise in Quantum Ballistic and Diffusive Lattice Systems
E. J. Amanatidis, D. E. Katsanos, S. N. Evangelou
We demonstrate fractal noise in the quantum evolution of wave packets moving either ballistically or diffusively in periodic and quasiperiodic tight-binding lattices, respectively.…
Level-spacing distribution of a fractal matrix
D. E. Katsanos, S. N. Evangelou
We diagonalize numerically a Fibonacci matrix with fractal Hilbert space structure of dimension We show that the density of states is logarithmically normal while…
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…
