Hans A. Bethe (1906–2005)

6 J ul 2 00 5 Hans Bethe and the Global Energy Problems . Boris Ioffe

Bethe’s view-point on the global energy problems is presented. Bethe claimed that the nuclear power is a necessity in future. Nuclear energetic must be based on breeder reactors. Bethe considered the non-proliferation of nuclear weapons as the main problem of long-range future of nuclear energetics. The solution of this problem he saw in heavy water moderated thermal breeders, using uranium-233...

Hans Thoenen: A Tribute

Hans Thoenen: 1928–2012 Hans Thoenen passed away on June 23, 2012, a fewmonths after being diagnosed with lung cancer. He left us grateful for what he had been able to accomplish in his life as scientist, but he was neither exuberant nor proud. Hans remained extraordinarily modest about his achievements—he felt far more comfortable by understating his contributions and never liked receiving com...

Spin systems on hypercubic Bethe lattices: A Bethe-Peierls approach

We study spin systems on Bethe lattices constructed from ddimensional hypercubes. Although these lattices are not tree-like, and therefore closer to real cubic lattices than Bethe lattices or regular random graphs, one can still use the Bethe-Peierls method to derive exact equations for the magnetization and other thermodynamic quantities. We compute phase diagrams for ferromagnetic Ising model...
