Multifractality and chaos in spin chainsMI 03.10.011 (Boltzmannstr. 3, 85748 Garching)
Spin-chain models are archetypical examples of many-body problems. Three subjects related with such models (but not restricted only for them) will be briefly discuss: multifractality of low-lying states, statistical description of high-excited states, and Gaussian and multi-Gaussian approximations for spectral densities.
