A highly unconventional superconducting state with a spin-singlet $ d_ {x^ 2-y^ 2}\pm {\rm i}
d_ {xy} $-wave, or chiral d-wave symmetry has recently been suggested to emerge from …

The recent discovery of AV 3 Sb 5 (A= K, Rb, Cs) has uncovered an intriguing arena for
exotic Fermi surface instabilities in a kagome metal. Among them, superconductivity is found …

Quantum walks provide a framework for designing quantum algorithms that is both intuitive
and universal. To leverage the computational power of these walks, it is important to be able …

We study the half-filled extended Hubbard model on a two-dimensional square lattice using
cluster dynamical mean-field theory on clusters of size 8–20. We show that the model …

We study the square-lattice extended Hubbard model with on-site U and nearest-neighbor V
interactions by exact diagonalization. We show that nonequilibrium quench dynamics can …

We examine the phase diagram of the extended Hubbard model on a square lattice, for both
attractive and repulsive nearest-neighbor interactions, using CDMFT+ HFD, a combination …

We present a generalization of the recently proposed variational cluster perturbation theory
to extended Hubbard models at half-filling with repulsive nearest neighbor interaction. The …

To study digital Mott insulator LaTiO 3 and band insulator SrTiO 3 interfaces, we apply
correlated band theory within the local density approximation including a Hubbard U to (n …
