Fermion bag study of the two-dimensional Majorana-Hubbard model at finite hopping
The two-dimensional Majorana-Hubbard model on the $\pi$-flux lattice involves the most local interaction possible for a lattice with one relativistic Majorana fermion per site. It is predicted to host a Majorana semimetal, dimerized phases, and quantum-critical points with an emergent $U(1)$ symmetry. Nonperturbative l...
