“…As expressed by Duncan, “electrons and positrons are strongly localized in directions transverse to the field” at fields near B Q . Ultrastrong B-fields can even alter the multiplicity of molecules . These facts, coupled with the breakdown of Maxwell equations, at ultrahigh B-fields, would seem to obviate the need of a strong gradient in the external field.…”

Pasteur was the first to realize Earth’s homochirality. Consequently, he attempted to design experiments revealing a mechanism that would expose life’s chiral preference. Some of these experiments involved the application of magnetic fields to chemical reactions. His experiments failed, in part, because B-fields are pseudo-vectors and cannot couple preferentially to one handedness. However, extremely large magnetic fields cause the Maxwell equations to break down. This allows the motions of spin and charge densities in paramagnetic anion radicals to produce polarized axial B-fields that can undergo preferential coupling to one handedness. Hence, when a racemic mixture of paramagnetic organic molecules passes by an extremely large external gradated magnetic field, the enantiomers experience different torque forces and acquire different translational directions. B-fields of the required magnitude are unknown on this planet. In fact, they would be lethal, thereby eliminating any chance of Pasteur’s success. On the other hand, Duncan and co-workers have recently discovered and garnered physical understanding of magnetars in interstellar space. Some of these neutron star systems produce B-fields greater than the quantum electrodynamic field strength, which is more than enough to generate the required torque for the interstellar enantiomeric separation. In space, chiralitically enriched materials can be deposited on planetesimals and result in homochiral “islands” on the planets. The formation of magnetars is a consequence of weak force events. We assert that, in interstellar space, a plethora of enantiomerically enriched dust clouds resulted from inter-magnetar-paramagnetic molecule force fields.

“…We use a finite-field approach, where the magnetic-field effects are incorporated directly without perturbative approximations. Although higher-order perturbation theory is sometimes an alternative to probe high-field effects [39][40][41][42][43][44], a nonperturbative approach is needed to study reliably potential-energy surfaces and level crossings in a strong field. To handle the gauge-origin problem and ensure faster basis-set convergence, we employ London atomic orbitals [45][46][47][48].…”
