The Bohr atom and the Uncertainty Principle
... Suppose an electron is inside a box 1 nm in width. There is some uncertainty in the momentum of the electron. We then squeeze the box to make it 0.5 nm. What happens to the momentum? ...

lesson 6: Heisenberg Uncertainty Principle
... One of the reasons why computer chips have been able to get smaller is that they are using shorter wavelengths to draw the pattern on the chips. “Current state-of-the-art photolithography tools use deep ultraviolet (DUV) light with wavelengths of 248 and 193 nm, which allow minimum feature sizes dow ...

... We demonstrate the experimental realization of Bohr -like atoms by applying a pulsed unidirectional field, termed a half-cycle pulse (HCP), to atoms in quasi-two-dimensional nearcircular states. This leads to creation of localized wave packets that travel in near-circular orbits and mimic the dynami ...
