New Journal of Physics, Vol 17, Iss 3, p 033034 (2015)
By applying dynamical mean-field theory in combination with exact diagonalization at zero temperature to a half-filled Hubbard model with two orbitals having distinct noninteracting densities of states, we show that an orbital selective Mott transiti

The acceleration of exact continuous time quantum Monte Carlo (CTQMC) approaches in multi-site or multi-orbital systems is extremely interesting work, because these approaches are very time-consuming in terms of numerical computation and might accoun

Since the local and elastic strain induced by nanobubbles largely affects the transport properties of graphene, detecting and probing nanobubbles are important processes for research on electronic transport in graphene. In this study, we propose a me

The one-dimensional t 1 − t 2 half-filled Hubbard model is considered at finite temperatures T within a dynamical cluster approximation (DCA) with N c = 24 in combination with a semiclassical approximation (SCA) impurity solver. The SCA approach ac

Via a dynamical cluster approximation with N c = 4 in combination with a semiclassical approximation (DCA+SCA), we study the doped two-dimensional Hubbard model. We obtain a plaquette antiferromagnetic (AF) Mott insulator, a plaquette AF ordered meta

An acceleration of continuous time quantum Monte Carlo (CTQMC) methods is a potentially interesting branch of work as they are matchless as impurity solvers of a density functional theory in combination with a dynamical mean field theory approach for

Understanding complex correlated oxides and their phase transitions has long been a challenge. The difficulty largely arises from the intriguing interplay between multiple degrees of freedoms. While degeneracy can play an important role in determinin

On the basis of first-principles calculations, we present exotic geometrical and electronic properties in hydrogenated graphyne, a 2D material of sp–sp2 hybrid carbon networks. Hydrogen atoms adsor...
