Thermal bath effect on soliton propagation in three-level atomic system
MetadataShow full item record
In a three-level media coupled to the thermal bath, an analytical expression of the soliton shapes have been derived. The velocity of these solitons depends mainly on the amplitude of the stationary control field, the coupling with the thermal bath and the detuning. Especially, we show that for a given value of the detuning, the soliton can be completely stopped.
