Abstract
Several studies in quantum mechanics and statistical mechanics have formally established that nonflat metrics induce a difference in the potential used to define the path-integral Lagrangian from that used to define the differential Schrödinger Hamiltonian. A recent study has described a statistical-mechanical biophysical system in which this effect is large enough to be measurable. This study demonstrates that the nucleon-nucleon velocity-dependent interaction derived from meson exchanges is a quantum-mechanical system in which this effect is also large enough to be measurable.
