DESCRIPTION:Speaker: Joscha Henheik\nhosted by Laszlo Erdös\nAbstract: We 
 prove that a class of weakly perturbed Hamiltonians of the form $H_\\lambd
 a = H_0 + \\lambda W$\, with $W$ being a Wigner matrix\, exhibits pretherm
 alization. That is\, the time evolution generated by $H_\\lambda$ relaxes 
 to its ultimate thermal state via an intermediate prethermal state with a 
 lifetime of order $\\lambda^{-2}$. Moreover\, we obtain a general relaxati
 on formula\, expressing the perturbed dynamics via the unperturbed dynamic
 s and the ultimate thermal state. The proof relies on a two-resolvent law 
 for the deformed Wigner matrix $H_\\lambda$. Based on a joint work with L
 . Erdös\, J. Reker\, and V. Riabov.
