Query: Tunable Line Node Semimetals   Weyl semimetals are examples of a new class of topological states of matter
which are gapless in the bulk with protected surface states. Their low energy
sector is characterized by massless chiral fermions which are robust against
translationally invariant perturbations. A variant of these systems have two
non-degenerate bands touching along lines rather than points. A proposal to
realize such a phase involves alternating layers of topological insulators and
magnetic insulators, where the magnetization lies perpendicular to the symmetry
axis of the heterostructure. The shape, size and the dispersion in the vicinity
of the nodal lines varies with the strength of the magnetization, offering a
new knob to control the properties of the system. In this paper we map out the
evolution of the nodal lines and the dependence of the conductivity on
magnetization and identify signatures of the low energy sector in quantum
oscillation measurements.
