Eigenstate thermalization hypothesis versus Bohigas-Giannoni-Schmit conjecture: a comparison
Hans A. Weidenmüller
Thermalization of a closed chaotic quantum system is commonly addressed in terms of the eigenstate thermalization hypothesis (ETH). An alternative approach uses the Bohigas-Giannon…
The rise of stochasticity in physics
Hans A. Weidenmüller
In the last 175 years, the physical understanding of nature has seen a revolutionary change. Until about 1850, Newton's theory and the mechanical world view derived from it provide…
Out-of-Time Ordered Correlator for a Chaotic Many-Body Quantum System
Hans A. Weidenmüller
Using the parametric representation of a chaotic many-body quantum system derived earlier, we calculate explicitly the large-time dependence and asymptotic value of the out-of-time…
Statistical Theory of Neutron-Induced Nuclear Fission and of Heavy-Ion Fusion
Hans A. Weidenmüller
For both reactions we use an approach similar to that of compound-nucleus reaction theory. For neutron-induced fission, we describe the compound system generated by absorption of t…
