Abstract: | The dynamical properties of quantum entanglement in an integrable
quantum dimer are studied in terms of the reduced-density linear entropy
with various coupling parameters and total boson numbers. The characteristic
time of decoherence process in the early-time evolution of the linear entropy
is obtained, indicating that the characteristic time and the corresponding
entropy exhibit a maximum near the position of the corresponding classical
separatrix energy. |
