# Dimensional crossover of effective orbital dynamics in polar distorted $^{3}\mathrm{He}\text{−}\mathrm{A}$: Transitions to antispacetime

J. Nissinen, G. E. Volovik
Topologically protected superfluid phases of $^{3}\mathrm{He}$ allow one to simulate many important aspects of relativistic quantum field theories and quantum gravity in condensed matter. Here we discuss a topological Lifshitz transition of the effective quantum vacuum in which the determinant of th...
