Spin Squeezing on an Atomic Clock Transition.
... Fig. 2. Measurement-induced pseudo-spin squeezing on an atomic clock transition. (a) Setup. A laser-cooled ensemble of 87 Rb atoms is loaded into a far-detuned optical dipole trap inside an optical resonator. A population difference N between hyperfine clock states |1⟩ , |2⟩ produces a resonator frequ ...

... to state | 4i through the coupling laser ®eld, which results in an a.c. Stark shift of level | 2i and a corresponding line shift of the 2 ! 3 transition. As the transparency peak and unity refractive index are obtained at two-photon resonance, this leads to a refractive index at the 1 ! 3 resonance ...
A conformal field theory approach to the fractional quantum Hall
... To theoretically explain the fractional quantum Hall states, the Coulomb force between the many particles needs to be taken into account, which makes the construction of the wave functions analytically impossible. By making educated guesses, many wave functions describing the FQHE at different fract ...

This condition is equivalent to the self-evident statement that an observation of a system must definitely result in one of its possible outcomes. There is another way in which we ...

Initially, all three coins are covered, so I don't know whether the coin is heads or tails (I don't know whether the spin is up or down along this axis). But I ...
