Query: On a Hamiltonian form of an elliptic spin Ruijsenaars-Schneider system   An explicit expression of a Hamiltonian form of an elliptic spin
Ruijsenaars-Schneider is found in the case of 2 particles using
Krichever-Phong's universal symplectic form. In the rational limit it coincides
with a Poisson bracket found by Arutyunov and Frolov.
