 Lyre (2004) and Healey (2004) see electromagnetism and other gauge theories as manifesting nonseparability for reasons different from those arising from quantum entanglement (cf.  The Aharonov-Bohm Effect).  Lyre takes this to be a variant of spatiotemporal holism, and connects it to structural realism. Healey (2007) argues that general relativity does not manifest this kind of nonseparability even though it may be formulated as a gauge theory. Weatherall (2016) argues that a distinction exists, but it is not enough to rule out spatiotemporal holism in general relativity. If there are more than one spatial dimensions, an analogue of the Aharonov-Bohm effect in general relativity (using the directions of parallel-propagated vectors) theoretically exhibits a similar type of nonseparability as that observed in gauge theory.
