16 Facts About Quantum tunneling
1.
2.
Quantum tunneling is not predicted by the laws of classical mechanics where surmounting a potential barrier requires potential energy.
| FactSnippet No. 1,553,663 |
3.
Quantum tunneling plays an essential role in physical phenomena such as nuclear fusion and alpha radioactive decay of atomic nuclei.
| FactSnippet No. 1,553,664 |
4.
Quantum tunneling was developed from the study of radioactivity, which was discovered in 1896 by Henri Becquerel.
| FactSnippet No. 1,553,665 |
5.
Quantum tunneling employed Earhart's method for controlling and measuring the electrode separation, but with a sensitive platform galvanometer.
| FactSnippet No. 1,553,666 |
6.
Quantum tunneling was first noticed in 1927 by Friedrich Hund while he was calculating the ground state of the double-well potential.
| FactSnippet No. 1,553,667 |
7.
Quantum tunneling realised that it was not restricted to nuclear physics, but was a general result of quantum mechanics that applied to many different systems.
| FactSnippet No. 1,553,668 |
8.
Quantum tunneling falls under the domain of quantum mechanics: the study of what happens at the quantum scale.
| FactSnippet No. 1,553,669 |
9.
In canonical field theory, the Quantum tunneling is described by a wave function which has a non-zero amplitude inside the tunnel; but the current is zero there because the relative phase of the amplitude of the conjugate wave function is orthogonal to it.

10.
Concept of quantum tunneling can be extended to situations where there exists a quantum transport between regions that are classically not connected even if there is no associated potential barrier.
| FactSnippet No. 1,553,671 |
11.
Concept of dynamical tunneling is particularly suited to address the problem of quantum tunneling in high dimensions.

12.
Resonant tunneling diode makes use of quantum tunneling in a very different manner to achieve a similar result.
| FactSnippet No. 1,553,673 |
13.
Radioactive decay is a relevant issue for astrobiology as this consequence of quantum tunneling creates a constant energy source over a large time interval for environments outside the circumstellar habitable zone where insolation would not be possible or effective.
