Quantum dot defined in a two-dimensional electron gas at a n
... formed in the gated two-dimensional electron gas. We focus our attention on the nanodevice that is probed by the quantum point contact as described in Refs. 9 and 10. The electrostatic confinement potential in vertical quantum dots was thoroughly studied in Refs. 19–26. Less attention was paid to do ...

Variation of the Gravitational Constant and its Consequences
... It must be realised however that Schwarzschild himself first stated this relation in 1917 in a paper designed to demonstrate that Einstein’s (then) new general theory of relativity necessarily implied an inner bound or horizon to the universe. This was in addition to the outer bound (now identified ...

... But that was not enough. In the next step, after laborious and detailed work, Ashtekar's version of Einstein's equations was successfully extended so that they could be quantized. "What we found exceeded our wildest expectations," remembers Lee Smolin. Together with the Italian physicist Carlo Rovel ...

For 800 nm and longer wavelength light interacting with many atoms and molecules tunnelling is an excellent approxim ...

Freezing of Reality: Is Flow of Time Real?

In such a perspective, all time moments exist at once, “simultaneously”, while the flow of time, past, present and future, are only an illusion ...

Quantum Mechanics in One Dimension
... The fundamental problem of quantum mechanics is this: Given the wavefunction at some initial instant, say t ⴝ 0, find the wavefunction at any subsequent time t. The wavefunction ⌿(x, 0) represents the initial information that must be specified; once this is known, however, the wave propagates accord ...
