Abstract
The standard -symmetric dimer is a linearly coupled two-site discrete nonlinear Schrödinger equation with one site losing and the other one gaining energy at the same rate. We show that despite gain and loss, the standard dimer is a Hamiltonian system. We also produce a Lagrangian formulation for the dimer.
