... beta decay). The mass difference between the neutron and the proton could then be attributed to the charge content of the latter. If the mass difference (or the energy difference) were to be to be purely electrostatic in nature, the proton had to be heavier. However, the proton is the lighter of the tw ...

Angular Momentum Coupling and Rabi Frequencies for Simple
... 2π×107 Hz.48 We may neglect spontaneous emission (recovering the Rabi-flopping behaviour described by Eqs. (1)) if Ωe←g A. However, this requires very high laser intensities. Although spontaneous emission is driven by only a “half photon” in each vacuum mode, there are an immense number of such mo ...

Novel Results for Condensed Matter Systems with Time Reversal Symmetry

The fact that superconductivity is associated with breaking of particle number conservation hints at the idea that in mesoscopic systems superconductivity can quite different from that of bulk systems. In this work we focus on extreme case of the so-called zerodimens ...

relativistic stern-gerlach deflection
... a “longitudinal” axis. Lorentz boosts occur only along this axis, and fields that are transverse in any frame are transverse in every frame. The vector operator ∇ can therefore, if one wishes, be everywhere replaced by ∇⊥ . (This would not be valid at entrances and exits of magnets or electric eleme ...

Effective Quantum Spin Systems with Trapped Ions

We have two cases, depending on the orientation of the pushing forces: (a) Axial force. The equilibrium position of the ions are suc ...

Quantum Phase Transitions - Subir Sachdev
... Normally, we do this by raising temperature. The resulting phase transition between phases characterized by (1) and (2) is well understood, and described by the well-developed theory of classical phase transitions. This shall not be our interest here. Rather, we are interested in moving from magneti ...

Generating entangled spin states for quantum metrology by single-photon detection
... q 1 is the photon detection efficiency. The probability of the incident photon being scattered into free space by the atomic ensemble is psc = 2Sη(/2)2 = 2Sφ 2 /η [35]. Therefore the success probability is simply related to the free-space scattering probability via p = qηpsc /4. A cavity increas ...
