Open-shell nanographenes can be covalently bonded and still preserve their local
moments, forming interacting spin lattices. In the case of benzenoid nanographenes, the …

The topological phases of graphene with spin-orbit coupling, an exchange field, and a
staggered-sublattice potential determine the properties of the edge states of the zigzag …

Step edges of topological crystalline insulators can be viewed as predecessors of higher-
order topology, as they embody one-dimensional edge channels embedded in an effective …

A bstract Boundary conditions for a massless Dirac fermion in 2+ 1 dimensions where the
space is a half-plane are discussed in detail. It is argued that linear boundary conditions that …

We examine the magnetic correlations in quantum spin models that were derived recently as
effective low-energy theories for electronic correlation effects on the edge states of graphene …

We investigate magnetic, charge, and transport properties of hexagonal graphene
nanoflakes (GNFs) connected to two metallic leads by using the functional renormalization …

The flat band of edge states that occur in the simple tight-binding lattice model of graphene
with a zigzag edge have long been conjectured to take up a ferromagnetic configuration. In …

We perform projective quantum Monte Carlo simulations of zigzag graphene nanoribbons
within a realistic model with long-range Coulomb interactions. Increasing the relative …

To synthesize nonmetallic magnets containing exclusively sp orbitals with high magnetic
moments and magnetic ordering is a great challenge in physics and material science. In this …

In this paper, we investigate the effects of uniaxial and oblique strain on Non-linear transport
of zigzag graphene nanoribbons using non-equilibrium Green's function formalism. The …
