Graphene has attracted increasing attention due to its unique electrical, optical,
optoelectronic, and mechanical properties, which have opened up huge numbers of …

We report multipronged progress on the stochastic averaging approach to numerical
analytic continuation of imaginary-time correlation functions computed by quantum Monte …

Graphene nanoribbons (GNRs) are one-dimensional nanostructures predicted to display a
rich variety of electronic behaviors. Depending on their structure, GNRs realize metallic and …

Topological insulators have become one of the most active research areas in condensed
matter physics. This article reviews progress on the topic of electronic correlation effects in …

Graphene is the strongest material ever studied and can be an efficient substitute for silicon.
This six-volume handbook focuses on fabrication methods, nanostructure and atomic …

We prove that the Kane-Mele-Hubbard model with purely imaginary next-nearest-neighbor
hoppings has a particle-hole symmetry at half filling. Such a symmetry has interesting …

Employing the recently developed momentum-space quantum Monte Carlo scheme, we
study the dynamic response of single-particle and collective excitations in realistic …

Using a model Hamiltonian approach including electron-electron interactions, we
systematically investigate the electronic structure and magnetic properties of chiral …

We calculate the strength of the effective on-site Coulomb interaction (Hubbard U) in two-
dimensional transition-metal (TM) dihalides MX 2 and trihalides MX 3 (M= Ti, V, Cr, Mn, Fe …

A method for analytic continuation of imaginary-time correlation functions (here obtained in
quantum Monte Carlo simulations) to real-frequency spectral functions is proposed …
