Sub-Doppler forces for 137 Ba ions
内容： In this talk I present a theoretical study of calculating sub-Doppler forces for 137 Ba ions. The D1 transition line is employed for cooling line. Two cooling schemes are used: (i) Fg=1 - Fe=2 ...

Informational Approach to Identical Particles in Quantum Theory
内容： A remarkable feature of quantum theory is that particles with identical intrinsic properties must be treated as indistinguishable if the theory is to give valid predictions. For example, our un...
