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 ...

... 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 ...

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