Cartesian coupling between stochastic circular limit-cycle oscillators reduces steady-state entropy production rate compared with the uncoupled system, independent of effective temperature and population size, while radial and phase couplings produce more variable effects.
(110) This expression greatly simplifies at k = 0 since any covariance terms between oscillator coordinates vanish, i.e., Cov0(rn i,r m j ) = 0 for all n,m and i ̸= j

Energetics of stochastic limit-cycle oscillators: when does coupling reduce dissipation?
