We will also measure the time the particles take to travel a known distance, which gives us the velocity. Using this we can find what velocities correspond to what momenta. This will allow us to compare the ...

From Irrational to Non-Unitary: on the Haffnian and Haldane
... no more than k particles can occupy two neighboring orbitals8 , and the number of multiplets at a certain L can be obtained as the difference between the number of states at Lz , Lz + 1 (see also [13]). For the Haffnian, the main rule is that no more than two particles can occupy four consecutive or ...

The key point is that the amplifier must be able to convert the input power into the frequency determined by the signal. This is usually ...

Experiments with single photons

... GHZ and Bell’s theorem In 1935, after failing for years to defeat the uncertainty principle, Einstein argued that quantum mechanics is incomplete. Note that [x, ˆp] ≠ 0, but [x2–x1, pˆ 2+pˆ 1] = [x2, pˆ 2] – [x1, pˆ1] = 0. That means we can measure the distance between two particles and their total ...
