    "abstract": "In order to extend the recently proposed Monte Carlo Hamiltonian to many-body\nsystems, we suggest to concept of a stochastic basis. We apply it to the chain\nof $N_s=9$ coupled anharmonic oscillators. We compute the spectrum of excited\nstates in a finite energy window and thermodynamical observables free energy,\naverage energy, entropy and specific heat in a finite temperature window.\nComparing the results of the Monte Carlo Hamiltonian with standard Lagrangian\nlattice calculations, we find good agreement. However, the Monte Carlo\nHamiltonian results show less fluctuations under variation of temperature.",
