Entanglement Dynamics of Second Quantized Quantum Fields

Figure 3

(a) A characteristic pattern of 𝜂(𝑡) due to partial recoveries of coherence is illustrated for 𝑛=15 and 𝑁=3. Time is measured in 𝑉⁻¹. (b) Dotted and solid lines show 𝜂(𝑡) for 𝑛=5 (prime number) and 𝑛=6=3!, respectively. This demonstrates that the number of times entangled states are encountered within one period depends on factorization properties of 𝑛.
