Tunable correlations in a 2x2 hermitian random matrix modelPierpaolo VivoSatya N. Majumdar
(A (T), B (T)T = Φ(q)(A (0), B (0))T, the quasi energies E±(q) of the two mini bands for the Hamiltonian Hˆ are defined as the eigenvalues of the 2 × 2 matrix (q). Quasi energies are defined apart from integer multiples than ω/N; for the sake of...
