Improved accuracy of the NPL-CsF2 primary frequency standard: evaluation of distributed cavity phase and microwave lensing frequency shifts
NPL-CsF2 primary frequency standard cavity phase microwave lensing frequency shifts
2011/8/17
Abstract: We evaluate the distributed cavity phase and microwave lensing frequency shifts, which were the two largest sources of uncertainty for the NPL-CsF2 cesium fountain clock. We report measureme...
Evaluation of ground state entanglement in spin systems with the random phase approximation
Evaluation ground state entanglement spin systems random phase approximation
2010/10/19
We discuss a general treatment based on the mean field plus random phase approximation (RPA)
for the evaluation of subsystem entropies and negativities in ground states of spin systems. The approach ...

The Lagrangian of a system describing the dynamical behaviour of a time-dependent harmonic oscillator is modified and then used to evaluate the Feynman path integral of the oscillator. The path integr...
