Chaos in fermionic many-body systems and the metal-insulator transition
T. Papenbrock, Z. Pluhar, J. Tithof +1
We show that finite Fermi systems governed by a mean field and a few-body interaction generically possess spectral fluctuations of the Wigner-Dyson type and are, thus, chaotic. Our…

Spectral fluctuation properties of constrained unitary ensembles of Gaussian-distributed random matrices
Z. Pluhar, H. A. Weidenmueller
We investigate the spectral fluctuation properties of constrained ensembles of random matrices (defined by the condition that a number N(Q) of matrix elements vanish identically; t…
