“…To physically interpret the GLD distributed torques, it is necessary to resort to an extended theory of continuum mechanics. In micropolar continuum theories, these torques can be balanced locally by invoking a couple stress field m, which in equilibrium satisfies ϵ i jk σ jk ¼ ∇ l m il , where ϵ ijk is the Levi-Civita symbol [12,[39][40][41]. In our situation, however, there is no compelling physical justification for this field since the primary objects of our model are achiral point particles [41] and there is no apparent external source for m. Thus, although the connection between the nonsymmetry of the IK-GLD stress and molecular chirality is very appealing, this example undermines its mechanical interpretation.…”
