Quantum Transport and Magnetism of Dirac Electrons in Solids
Hiroki Isobe, Naoto Nagaosa
The relativistic Dirac equation covers the fundamentals of electronic phenomena in solids and as such it effectively describes the electronic states of the topological insulators l…
Density functional approach to correlated moire states: itinerant magnetism
Yang Zhang, Hiroki Isobe, Liang Fu
Two-dimensional moire superlattices have recently emerged as a fertile ground for creating novel electronic phases of matter with unprecedented control. Despite intensive efforts,…
Supermetal
Hiroki Isobe, Liang Fu
We study the effect of electron interaction in an electronic system with a high-order Van Hove singularity, where the density of states shows a power-law divergence. Owing to scale…
Magic of high order van Hove singularity
Noah F. Q. Yuan, Hiroki Isobe, Liang Fu
We introduce a new type of van Hove singularity in two dimensions, where a saddle point in momentum space is changed from second-order to high-order. Correspondingly, the density o…
Unconventional Superconductivity and Density Waves in Twisted Bilayer Graphene
Hiroki Isobe, Noah F. Q. Yuan, Liang Fu
We study electronic ordering instabilities of twisted bilayer graphene with electrons per supercell, where correlated insulator state and superconductivity are recently obser…
Interlayer Pairing Symmetry of Composite Fermions in Quantum Hall Bilayers
Hiroki Isobe, Liang Fu
We study the pairing symmetry of the interlayer paired state of composite fermions in quantum Hall bilayers. Based on the Halperin-Lee-Read (HLR) theory, the effect of the long-ran…
