Anomalously large critical regions in power-law random matrix ensembles
E. Cuevas, V. Gasparian, M. Ortuno
We investigate numerically the power-law random matrix ensembles. Wavefunctions are fractal up to a characteristic length whose logarithm diverges asymmetrically with different exp…

Non-ergodic effects in the Coulomb glass: specific heat
A. Díaz-Sánchez, A. Möbius, M. Ortuño +2
We present a numerical method for the investigation of non-ergodic effects in the Coulomb glass. For that, an almost complete set of low-energy many-particle states is obtained by…
