Photoisomers appear across nature and technologies, from our eyes to solar-fuel cells. How effectively can these switches switch? A general answer defies standard analyses, because photoisomers are small, quantum, and far from equilibrium. We model a photoisomer in a thermodynamic resource theory, then upper-bound the switching probability using thermomajorization, a resource-theory result that extends the second law of thermodynamics to small scales. Thermomajorization constrains the yield tightly if a laser barely excites the molecule, as in solar-fuel experiments. This work demonstrates that thermodynamic resource theories can illuminate nature, experiments, and materials. NYH and Limmer, Phys. Rev. A 101, 042116 (2020).
