Fredenhagen-Marcu Order Parameter: Critical Behavior for Topological Phase Transitions

Wen-Tao Xu from the Technical University of Munich provides PyTorch code for optimizing infinite projected entangled-pair states (iPEPS) and plotting figures. This code supports research on the critical behavior of the Fredenhagen-Marcu order parameter, which is used to characterize topological phase transitions in quantum systems. The dataset's cross-platform presence on Papers with Code indicates its utility for computational physics research.

Use Cases

• [Optimizing iPEPS tensor network parameters] based on [the provided PyTorch code]
• [Analyzing critical exponents at phase transitions] based on [the Fredenhagen-Marcu order parameter]
• [Reproducing figures from the associated research paper] based on [the included plotting code]
• [Benchmarking tensor network optimization algorithms] based on [the provided physics model implementation]

Strengths

• [Open Access (green) license] ensures the code is freely available for academic use.
• [Cross-platform presence on Papers with Code] suggests established utility and importance in the research community.
• [Associated with a specific research paper and author] provides clear academic provenance and context.

Limitations

• [No dataset size, row count, or specific column information] is provided, limiting assessment of data scale and structure.
• [Metadata completeness is low] with unknown last update dates and file formats.
• [The description focuses on code, not a traditional dataset, so the primary content is software for generating data.]
