Multifractal finite-size scaling at the Anderson transition in the unitary symmetry class — Jakob Lindinger, Andreas Buchleitner, and •Alberto Rodríguez — Physikalisches Institut, Universität Freiburg, Hermann-Herder-Str. 3, D-79104 Freiburg, Germany
We carry out a full characterisation of the Anderson transition in the unitary symmetry class. We apply multifractal finite-size scaling [A. Rodriguez, L. J. Vasquez, K. Slevin, R. A. Römer, Phys. Rev. B 84, 134209 (2011)] to the 3-D Anderson model subjected to a random magnetic field, and estimate the critical parameters as well as the multifractal exponents with high precision using wavefunction data of systems up to L3 = 1503. We also examine the scaling of the probability density function and the spatial correlations of the wavefunctions intensities as the system undergoes the transition.
