Query: Structure-preserving numerical schemes for Lindblad equations   We study a family of structure-preserving deterministic numerical schemes for
Lindblad equations, and carry out detailed error analysis and absolute
stability analysis. Both error and absolute stability analysis are validated by
numerical examples.
