Conformal Embeddings Unlock Exact Open Quantum System Evolution

Researchers have discovered a surprising pathway to exact solutions for complex, open quantum systems, revealing how intrinsic conformal structures can unlock analytically tractable dynamics. Chen Bai, of the Kavli Institute for Theoretical Sciences at the University of Chinese Academy of Sciences, demonstrates that for N Majorana fermions experiencing linear mode jumps, “the adjoint Lindbladian is triangular on reduced even Majorana monomials, yielding recursive exact Heisenberg evolution.” This means the system’s evolution can be predicted with precision, a rare feat in the chaotic realm of interacting quantum many-body systems. The work applies to Wess-Zumino-Witten models and rational conformal field theories, showing that conformal embeddings and modular data can organize…
