It is shown that the quantum dynamics of spin coherent states governed by quadratic spin-like Hamiltonians, in the large spin limit, is well described in terms of evolution along classical trajectories on the two-dimensional sphere. Two non-linear effects: (a) spin squeezing and (b) spin en...
The Raman π pulse serves the additional functions of re-overlapping the wave packets and cancelling the average light shift of the probe. Collective QND measurements are used in creating conditional spin squeezing. The spin-momentum projection in the population basis is measured once with the pre-...
squeezing converges exponentially fast to its asymptotic optimum, which we determine explicitly. For the case of multiple iterations we show that the optimumcan be achieved with fixed intermediate passive operations. Finally, we relate the results to the generation of entanglement and derive the maxi...
Entanglement and spin squeezing in non-Hermitian phase transitions We show that non-Hermitian dynamics generate substantial entanglement in many-body systems. We consider the non-Hermitian Lipkin-Meshkov-Glick model and sh... TE Lee,F Reiter,N Moiseyev - 《Physical Review Letters》 被引量: 10发表...
