Klein paradox
名詞
(quantum
mechanics)
A
surprising
result
of
applying
the
Dirac
equation
to
the
problem
of
electron
scattering
from
a
potential
barrier.
In
non-relativistic
quantum
mechanics,
electron
tunnelling
into
a
barrier
is
observed,
with
exponential
damping.
However,
if
the
potential
is
of
the
order
of
the
electron
mass,
V∼mc²,
the
barrier
is
nearly
transparent;
moreover,
as
the
potential
approaches
infinity,
the
reflection
diminishes
and
the
electron
is
always
transmitted.
日本語の意味
クラインパラドックス：量子力学において、ディラック方程式を用いて電子のポテンシャル障壁における散乱問題を解析する際に、通常の非相対論的な電子トンネル効果（指数減衰を伴う）とは対照的に、ポテンシャルが電子の質量エネルギー程度（V≈mc²）に達すると障壁がほぼ透明になり、ポテンシャルが無限に近づくと反射が減少し、常に透過するという予想外の現象を示すものです
