Shear viscosity of nuclear matter is extracted via the Green-Kubo formula and Gaussian thermostated SLLOD algorithm (the shear rate method) in a periodic box by using an improved quantum molecular dynamic (ImQMD) model without mean field, also it calculated Boltzmann-type equation. Here new form put forward present work. For classical limit at densities $0.4\rho_{0}$ $1.0\rho_{0}$, traditional ...

We construct supersymmetric(SUSY) generalized MIC-Kepler system and show that the systems with half integral Dirac quantization condition μ = ± 1 2 ,± 3 2 ,± 5 2 , ..... belong to a SUSY family (hierarchy of Hamiltonian) with same spectrum between the respective partner Hamiltonians except for the ground state. Similarly, the systems with integral Dirac quantization condition μ = ±1,±2,±3, .......

In this work, the systems are constructed with the defect lines of B-B or N-N dimers embedded in a graphene matrix using density functional theory. It is found that the Dirac-cone dispersions appear at the Fermi level in the bands introduced by the B or N heteroatom, linear B-B or N-N dimers, demonstrating that the carrier mobility is ∼10(6) m s(-1) which is comparable with that of the pristine...

: We investigate the Dirac cone in α-graphdiyne, which is a predicted flat one-atom-thick allotrope of carbon using first-principles calculations. α-graphdiyne is derived from graphene where two acetylenic linkages (-C ≡C-) are inserted into the single bonds (-C-C-). Thus, α-graphdiyne possesses a larger lattice constant which subsequently affects its electronic properties. Band structures show...
