چکیده
In this mid-term we will study the dynamics of an atomic clock, mF which is one of the applications of David Wineland’s research (No bel prize in physics 2012). We consider a simplified (and sometime inaccurate) model of a vapor-cell atomic clock . Light from a lamp passes through a vapor of rubidium atoms housed in a glass cell and is detected by a photodiode. The light intensity transmitted by the vapor is used to lock the frequency of an RF sig nal to an atomic transition. The atomic resonance that forms the basis of the Rubidium clocks operation is the transition between two hyperfine states F = 1, 2 of Rb (see figure). measure t 0 tμw t0

Consider an isolated electron with spin1 , placed in a large magnetic f eld ~ B = Bz~z at zero temperature. The spin is 2 in the state ψ = c0 + c1 where |↑〉 ≡ |S = + | 〉 |↑〉 |↓〉 z 〉 (|↓〉 ≡ |S ~ z = − 〉) represents the spin state aligned (anti-aligned) with the vertical z-axis. 2 2 We now assume that we can measure the magnetic dipole ~ ~μ = γS = γ σ~ ~ of this single spin (with γ the gyromagnet...

For most of this midterm exam we are interested in describing the quantum behavior of a particle –such as an atom or a ion– which is confined in a double well potential. The particle can be in either the left or right well. It has energy ER = E0 − ΔE in the right well and energy EL = E0 + ΔE in the left well. The barrier between the two wells is not very high, so the particle can tunnel between...

where we used the fact that (σ 2 z) = 1 . In general e−iφfn·fσ = 1 cos(φ)− in · nσ sin(φ) Now we consider a system composed of two subsystems H = H1 ⊗H2, each being a two-level system. To describe operators on the two subsystems we normally use the shorthanded notations A ≡ A ⊗ 1 2 and B ≡ 1 1 ⊗B2 and AB ≡ A ⊗B2 . a) What is (σσ) z z ? b) Consider the operator U = e− 1 iσ iσ φ⊗ z e− z : to whic...
