Continuous transition between Ising magnetic order and a chiral spin liquid
G. Shankar, Chien-Hung Lin, Joseph Maciejko
The competition between fractionalized spin-liquid states and magnetically ordered phases is an important paradigm in frustrated magnetism. Spin-orbit coupled Mott insulators with…
Corner- and sublattice-sensitive Majorana zero modes on the kagome lattice
Majid Kheirkhah, Di Zhu, Joseph Maciejko +1
In a first-order topological phase with sublattice degrees of freedom, a change in the boundary sublattice termination has no effect on the existence of gapless boundary states in…
Flat bands and band touching from real-space topology in hyperbolic lattices
Tomáš Bzdušek, Joseph Maciejko
Motivated by the recent experimental realizations of hyperbolic lattices in circuit quantum electrodynamics and in classical electric-circuit networks, we study flat bands and band…
Quantum-critical electrodynamics of Luttinger fermions
Santanu Dey, Joseph Maciejko
We study the quantum electrodynamics of Luttinger fermions with quadratic band-crossing dispersion in three dimensions. The model can be viewed as the low-energy effective theory o…
