How Close Can One Approach the Dirac Point in Graphene Experimentally?
The above question is frequently asked by theorists who are interested in graphene as a model system, especially in context of relativistic quantum physics. We offer an experime...
Numerical solution of Poisson’s equation in polyatomic molecules
We have developed a completely numerical scheme for solution of Poisson’s equation in multicenter systems. We are thus able to numerically calculate the Coulomb potential of arb...
The primordial helium abundance from updated emissivities
Observations of metal-poor extragalactic H II regions allow the determination of the primordial helium abundance, Y_p. The He I emissivities are the foundation of the model of t...
The five‐factor personality inventory: cross‐cultural generalizability across 13 countries
In the present study, we investigated the structural invariance of the Five‐Factor Personality Inventory (FFPI) across a variety of cultures. Self‐report data sets from ten Euro...
Constant temperature molecular dynamics calculation on Lennard-Jones fluid and its application to watera)
Constant temperature molecular dynamics calculation has been carried out on Lennard-Jones liquid simulating argon. This method, proposed recently by Andersen, intends to transfo...
Non-LTE model atmospheres for central stars of planetary nebulae
A grid of hot non-LTE model atmospheres with H and He opacity sources has been calculated. The emergent fluxes, together with integrals required for Zanstra and Energy-Balance m...
Perspectives on Variation
The significant advances witnessed over the last years in the broad field of linguistic variation testify to a growing convergence between sociolinguistic approaches and the som...
Ab Initio Calculations on the Electronically Excited States of Small Helium Clusters
The vertical excitation energies of small helium clusters, He(7) and He(25), have been calculated using configuration interaction singles, and the character of the excited state...
Shape of the Coexistence Curve near the Critical Temperature
It is shown that diffusion in the gravitational field in binary liquid systems is so slow that the effect of gravity may be completely neglected in studies of the coexistence cu...
