 Such strong magnetic fields can lead to more pronounced effects of chiral symmetry breaking, e.g., lead to (i) a larger value of the chiral condensate, (ii) a larger dynamical (constituent) mass of quarks, (iii) larger baryon masses, (iv) modified pion decay constant, etc.Recently, there was an increased activity to cross-check the effects of magnetic catalysis in the limit of a large number of colors, using the technique of AdS/CFT correspondence.The idea of magnetic catalysis can be used to explain the observation of new quantum Hall plateaus in graphene in strong magnetic fields beyond the standard anomalous sequence at filling factors ν=4(n+½) where n is an integer.
