Dynamics of Gaussian Wigner functions derived from a time-dependent variational principle
AIP ADVANCES(2017)
摘要
By using a time-dependent variational principle formulated for Wigner phase-space functions, we obtain the optimal time-evolution for two classes of Gaussian Wigner functions, namely those of either thawed real-valued or frozen but complex Gaussians. It is shown that tunneling effects are approximately included in both schemes. (C) 2017 Author(s).
