Purified Projection Method and Uhlmann Fidelity for Mixed Hartree Dynamics
Hao Liang, Zhenfu Wang
We give a purification and fidelity formulation of the projection method for mixed Hartree data. For the mean-field evolution of -particle density matrices, we prove quantitativ…

Quantum Relative Entropy and the Mean-Field Limit
Gaoyue Guo, Hao Liang, Zhenfu Wang
We develop a quantum relative entropy method for the mean-field limit of quantum many-body systems. For closed systems governed by the von Neumann equation, we prove a quantitative…
