A dataset of Collective quantum tunneling with time-dependent generator coordinate method

In the article, we apply the time-dependent generator coordinate method (TDGCM) to a solvable two-well model to systematically investigate whether a collective wave function constructed from real-time mean-field states can resolve the fundamental self-trapping limitation.

Furthermore, we conduct a comprehensive analysis of expectation values to extract underlying single-particle properties from the collective many-body state. The dataset, which includes five figures and their corresponding data, is stored in an OPJU file format and can be opened with the Origin software application.
