Bulk Dirac points in distorted spinels.
We report on a Dirac-like Fermi surface in three-dimensional bulk materials in a distorted spinel structure on the basis of density functional theory as well as tight-binding theory. The four examples we provide in this Letter are BiZnSiO4, BiCaSiO4, BiAlInO4, and BiMgSiO4. A necessary characteristic of these structures is that they contain a Bi lattice which forms a hierarchy of chainlike subs...
متن کاملMicroleakage of Bulk-Fill Composites at Two Different Time Points
Objectives: Microleakage is the main concern in composite restorations. This study aimed to compare the microleakage of two bulk-fill and one conventional composite at two different time points. Methods: Class II cavities were prepared in 60 premolar teeth and divided into six groups of 20. Groups 1 and 4 were incrementally filled with Grandio composite. Groups 2 and 5 were filled with X-tra...
متن کاملPlexciton Dirac points and topological modes
Plexcitons are polaritonic modes that result from the strong coupling between excitons and plasmons. Here, we consider plexcitons emerging from the interaction of excitons in an organic molecular layer with surface plasmons in a metallic film. We predict the emergence of Dirac cones in the two-dimensional band-structure of plexcitons due to the inherent alignment of the excitonic transitions in...
متن کاملHoneycomb Lattice Potentials and Dirac Points
In this article we study the spectral properties of the Schrödinger operator HV “ ́Δ ` V pxq, x P R, where the potential, V , is periodic and has honeycomb structure symmetry. For general periodic potentials the spectrum of HV , considered as an operator on LpRq, is the union of closed intervals of continuous spectrum called the spectral bands. Associated with each spectral band are a band dispe...
متن کاملTopological transition of Dirac points in a microwave experiment.
By means of a microwave tight-binding analogue experiment of a graphenelike lattice, we observe a topological transition between a phase with a pointlike band gap characteristic of massless Dirac fermions and a gapped phase. By applying a controlled anisotropy on the structure, we investigate the transition directly via density of states measurements. The wave function associated with each eige...
