Topological phases in quantum materials, lattice field theory and QCD

Srimoyee Sen (Iowa State) Topological phases of quantum materials are highly sought after due to their potential application to quantum computing. Surprisingly, they also share deep ties with lattice field theory. A classic example of this is the common thread connecting the physics of Kitaev's Majorana chain and the quantum Hall effect with lattice domain wall fermions. The latter enables QCD simulations while maintaining good global chiral symmetry. In this talk, I discuss some of these concepts that connect lattice QFT with topological materials and elaborate on the possibility of further cross-pollination of ideas from these two areas of research.
