| contents | Confinement can significantly alter fluid properties, offering potential for specific technological applications. However, achieving precise control over the structural complexity of confined fluids and soft matter remains challenging, as it often requires careful tuning of system parameters. In this study, we perform large-scale molecular dynamics simulations of a fluid confined in a slit pore, employing an interaction potential applicable to a broad range of soft matter. Confinement induces the fluid to form two-dimensional (2D) layers, each of which self-assembles into structures of varying complexity. Notably, we observe a suppression of large-scale density fluctuations-akin to crystals-within complex nontrivial fluid-like geometries, leading to the emergence of disordered hyperuniformity. We demonstrate that fluid properties can be precisely adjusted by modifying control parameters. This work provides a foundation for designing experimental protocols to regulate the structure of self-assembling materials, stabilize disordered hyperuniform structures, and facilitate the fabrication of 2D arrays with tailored complexity. Additionally, it offers a new perspective for analyzing biological monolayers, such as epithelial tissues. |
