Data for "Dark-state phase transition to a dark soliton in a dissipative Bose–Hubbard chain"

Dataset for: Dark-state phase transition to a dark soliton in a dissipative Bose-Hubbard chain

This dataset contains the simulation and experimental data used to produce the figures in:

    R. Ceulemans, S. E. Begg, M. J. Davis, and M. Wouters,
    "Dark-state phase transition to a dark soliton in a dissipative Bose-Hubbard chain",
    accepted (2026). Preprint: arXiv:2509.25707 (https://doi.org/10.48550/arXiv.2509.25707)

The companion plotting code is available at:
https://github.com/RobbeCeulemans/dark-state-phase-transition-to-dark-soliton

USAGE

Unzip this archive so the resulting "darkstatephase_data/" folder sits directly next to the "Fig_1"-"Fig_4" folders of the GitHub repository, i.e. at the repository root. The plotting scripts reference these files by relative path and will not run without it.

THIRD-PARTY DATA

The experimental phase-boundary data in fig4_3d_twa/ExpData.mat was NOT produced as part of this work. It reproduces a dataset first published in:

    R. Labouvie, B. Santra, S. Heun, and H. Ott,
    "Bistability in a Driven-Dissipative Superfluid",
    Phys. Rev. Lett. 116, 235302 (2016).

It was kindly provided directly by the authors of that paper for the purpose of overlaying their experimental phase boundary on Figure 4 and Figure E1. This file is NOT covered by the license below and all rights to it remain with them. Any further reuse of ExpData.mat should be directed to the authors of the 2016 paper above.
