Superconductivity at an antiferromagnetic quantum critical point: the role of energy fluctuations
Jian Kang, Rafael M. Fernandes, Elihu Abrahams +1
Motivated by recent experiments reporting superconductivity only at very low temperature in a class of heavy fermion compounds, we study the impact of energy fluctuations with smal…
Strong coupling phases of partially filled twisted bilayer graphene narrow bands
Jian Kang, Oskar Vafek
We identify states favored by Coulomb interactions projected onto the Wannier basis of the four narrow bands of the "magic angle" twisted bilayer graphene. At the filling of two el…
Symmetry, maximally localized Wannier states, and low energy model for the twisted bilayer graphene narrow bands
Jian Kang, Oskar Vafek
We build symmetry adapted maximally localized Wannier states, and construct the low energy tight binding model for the four narrow bands of the twisted bilayer graphene. We do so w…
Time-reversal symmetry-breaking nematic superconductivity in FeSe
Jian Kang, Andrey V. Chubukov, Rafael M. Fernandes
FeSe is a unique member of the family of iron-based superconductors, not only because of the high values of in FeSe monolayer, but also because in bulk FeSe superconductivi…
Superconductivity in FeSe: the role of nematic order
Jian Kang, Rafael M. Fernandes, Andrey V. Chubukov
Bulk FeSe is a special iron-based material in which superconductivity emerges inside a well-developed nematic phase. We present a microscopic model for this nematic superconducting…
