Chiral tunnelling and the Klein paradox in graphene
, 2006The so-called Klein paradox—unimpeded penetration of relativistic particles through high and wide potential barriers—is one of the most exotic and counterintuitive consequences of quantum electrodynamics.

It was shown earlier that during quantum mechanical tunnelling, a microscopic particle has a distributed probability of emission about its original energy and is not constrained to be field-emitted only at its initial energy. Such an energy distribution process appears obvious on the quantum theory of observation and measurement which relates the ...

Abstract A distinguishing feature of quantum mechanics, as compared with classical mechanics, is the phenomenon of matter exhibiting wave-like properties. A direct consequence of this wave property of particles is the tunneling of particles through potential energy barriers.-3 The classical particle is forbidden from penetrating the ...

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.
