Energy-difference conserving dynamics in time domain. a Measured time evolution of the total energy Tn, electric energy En, and magnetic energy Mn for an initial state |v(0)〉 = [0 1]T. We set ε = 1.48κ in this measurement. b Measured voltage-product energy rate V1V2/R. c Integrated voltage-product energy rate Σ(V1V2/R)Δt showing an exact correlation with the beating patterns in Tn. Here, the sampling time interval Δt = 4 μs
