We establish a direct link between Dunkl operators and quantum Lax matricesfor the Calogero–Moser systems associated to an arbitrary Weyl groupW(or an arbitrary finite reflection group in the rational case). This interpretation also provides a companion matrixso thatform a quantum Lax pair. Moreover, such ancan be associated to any of the higher commuting quantum Hamiltonians of the system, so we obtain a family of quantum Lax pairs. These Lax pairs can be of various sizes, matching the sizes of orbits in the reflection representation ofW, and in the elliptic case they contain a spectral parameter. This way we reproduce universal classical Lax pairs by D’Hoker–Phong and Bordner–Corrigan–Sasaki, and complement them with quantum Lax pairs in all cases (including the elliptic case, where they were not previously known). The same method, with the Dunkl operators replaced by the Cherednik operators, produces quantum Lax pairs for the generalised Ruijsenaars systems for arbitrary root systems. As one of the main applications, we calculate a Lax matrix for the ellipticBCncase with nine coupling constants (van Diejen system), thus providing an answer to a long-standing open problem.
