Non-uniform strain applied to graphene's honeycomb lattice can inducepseudo-Landau levels in the single-particle spectrum. Various generalizationshave been put forward, including a particular family of hopping models in $d$space dimensions. Here we show that the key ingredient for sharp pseudo-Landaulevels in higher dimensions is dimensional reduction. We consider particlesmoving on a $d$-dimensional hyper-diamond lattice which displays a semimetallicbandstructure, with a $(d-2)$-dimensional nodal manifold. By applying asuitable strain pattern, the single-particle spectrum evolves into a sequenceof relativistic Landau levels. We develop and solve the corresponding fieldtheory: Each nodal point effectively generates a Landau-level problem which isstrictly two-dimensional to leading order in the applied strain. While theeffective pseudo-vector potential varies across the nodal manifold, theLandau-level spacing does not. Our theory paves the way to strain engineeringof single-particle states via dimensional reduction and beyond global minimalcoupling.
