We use ring-theoretic methods and methods from the theory of skew braces to produce set-theoretic solutions to the reflection equation. We also use set-theoretic solutions to construct solutions to the parameter-dependent reflection equation.

  1. Integrable multi-species SSEP with reactive particle species

    math-ph 2026-07 accept novelty 6.0

    A new integrable family of exclusion processes, the (p,q)-SSEP, adds reactive particle pairs that transform or evaporate/condensate, with exact stationary densities and currents for one class of open boundaries.

  2. Twisted symmetric exclusion processes and set-theoretical $R$-matrices

    math-ph 2026-02 conditional novelty 6.0

    Lyubashenko solutions of the Yang-Baxter equation produce Markov processes equivalent to a twisted SSEP, whose stationary sectors are labeled exactly by a species profile and a total charge.
