Strongly Interacting Phases in Twisted Bilayer Graphene at the Magic Angle
Khagendra Adhikari, Kangjun Seo, K. S. D. Beach +1
Twisted bilayer graphene near the magic angle is known to have a cascade of insulating phases at integer filling factors of the low-energy bands. In this Letter we address the natu…
Non-Fermi liquid behavior in the Sachdev-Ye-Kitaev model for a one dimensional incoherent semimetal
Geo Jose, Kangjun Seo, Bruno Uchoa
Abstract We study a two-band dispersive Sachdev-Ye-Kitaev (SYK) model in 1 + 1 dimension. We suggest a model that describes a semimetal with quadratic dispersion at half-filling. W…
Ferromagnetic Mott State in Twisted Graphene Bilayers at the Magic Angle
Kangjun Seo, Valeri N. Kotov, Bruno Uchoa
We address the effective tight-binding Hamiltonian that describes the insulating Mott state of twisted graphene bilayers at a magic angle. In that configuration, twisted bilayers f…
Possible Chiral Topological Superconductivity in CrO bilayers
Xu Dou, Kangjun Seo, Bruno Uchoa
We address the possible emergence of spin triplet superconductivity in CrO bilayers, which are half-metals with fully spin-polarized conducting bands. Starting from a lattice…
3D Quantum Anomalous Hall Effect in Hyperhoneycomb Lattices
Sang Wook Kim, Kangjun Seo, Bruno Uchoa
We address the role of short range interactions for spinless fermions in the hyperhoneycomb lattice, a three dimensional (3D) structure where all sites have a planar trigonal conne…
Superconducting States for Semi-Dirac Fermions at Zero and Finite Magnetic Fields
Bruno Uchoa, Kangjun Seo
We address the superconducting singlet state of anisotropic Dirac fermions that disperse linearly in one direction and parabolically in the other. For systems that have uniaxial an…
