Theory of Moire Magnets and Topological Magnons: Applications to Twisted Bilayer CrI3
Kyoung-Min Kim, Do Hoon Kiem, Grigory Bednik +2
We develop a comprehensive theory of twisted bilayer magnetism. Starting from the first-principles calculations of two-dimensional honeycomb magnet CrI3, we construct the generic s…
Fluctuation-driven, topology-stabilized order in a correlated nodal semimetal
Nathan C. Drucker, Thanh Nguyen, Fei Han +19
The interplay between strong electron correlation and band topology is at the forefront of condensed matter research. As a direct consequence of correlation, magnetism enriches top…
Antiferromagnetism and spin density waves in 3D Dirac semimetals
Grigory Bednik
We perform mean-field study of possible magnetic instabilities in Dirac semimetals. We find that Dirac electrons naturally host antiferromagnetic or spin density wave ground states…
Probing trihedral corner entanglement for Dirac fermions
Grigory Bednik, Lauren E. Hayward Sierens, Minyong Guo +2
We investigate the universal information contained in the Renyi entanglement entropies for a free massless Dirac fermion in three spatial dimensions. Using numerical calculations o…
Surface states in Dirac metals and topological crystalline insulators
Grigory Bednik
We reconsider the problem of surface states spectrum in type One Dirac metals. We find that the surface states, despite being gapped, always form branches terminating at Dirac poin…
