    "abstract": "We study the effect of screening by bound electrons in low energy nuclear\nreactions. We use molecular dynamics to simulate the reactions involving many\nelectrons: D+$d$, D+D, $^3$He+$d$, $^3$He+D, $^6$Li+$d$, $^6$Li+D, $^7$Li+$p$,\n$^7$Li+H. Quantum effects corresponding to the Pauli and Heisenberg principles\nare enforced by constraints in terms of the phase space occupancy. In addition\nto the well known adiabatic and sudden limits, we propose a new \"dissipative\nlimit\" which is expected to be important not only at high energies but in the\nextremely low energy region. The dissipative limit is associated with the\nchaotic behavior of the electronic motion. It affects also the magnitude of the\nenhancement factor. We discuss also numerical experiments using polarized\ntargets. The derived enhancement factors in our simulation are in agreement\nwith those extracted within the $R$-matrix approach.",
