Abstract A fascinating result of quantum mechanics is that objects can tunnel through barriers even if they lack the energy to climb over them. Recent experiments involving carbene rearrangements demonstrate that these reactions proceed through quantum mechanical tunneling. An exciting outcome is that a third control mechanism, tunneling

The talk reviews some recent developments in the theory of quantum mechanical tunneling. The new phenomena discussed arise from the coupling of the tunneling system to a heat bath of temperature T. The question is how dissipation and thermal fluctuation affect the tunneling rate.

The positive muon (μ+) is one of the elementary particles classified as leptons, which is mass-produced as secondary ion beams in modern proton accelerator facilities. Because of the parity violation in the weak interaction which causes the parent pion (π +) to decay into a muon and a neutrino (ν μ ), muons are always 100% spin-polarized along the ...
