Proposal for measurement of the van der Waals interaction in a cold Rydberg ensemble via electromagnetically induced transparency

We propose a method of measuring the van der Waals interaction in an ensemble of cold Rydberg atoms via electromagnetically induced transparency (EIT). By using the method of mean-field approximation, we examine the influence of the van der Waals interaction on the EIT spectrum. It is interesting to find that the van der Waals interaction strength is proportional to frequency shift of the transmission spectrum. This can be used to probe the van der Waals interaction strength. In addition, we discuss the evolution of the van der Waals interaction by adopting the model of the cubic lattice. It is found that the total atoms blockade appears in dense gases under the condition of the strong coupling. Also, we discuss the boundary condition of the total blockade and explain the evolution of the van der Waals interaction.
