Elastic and electronic properties of hexagonal rhenium sub-nitrides Re3N and Re2N in comparison with hcp-Re and wurtzite-like rhenium mononitride ReN
Elastic electronic properties Re2N in comparison
2010/11/23
Very recently, two new hexagonal rhenium sub-nitrides Re3N and Re2N, which belong to a rather rare group of known metal-rich (M/N > 1) nitrides of heavy 4d,5d metals, have been successfully synthesize...
Comparison of Graphene Formation on C-face and Si-face SiC {0001} Surfaces
Comparison of Graphene Formation Si-face SiC {0001} Surfaces
2010/11/19
The morphology of graphene formed on the ( 0001 ) surface (the C-face) and the (0001) surface
(the Si-face) of SiC, by annealing in ultra-high vacuum or in an argon environment, is studied by atomic ...
Comparison of the mass preconditioned HMC and the DD-HMC algorithm for two-flavour QCD
Comparison mass preconditioned HMC DD-HMC algorithm two-flavour QCD
2011/1/13
Mass preconditioned HMC and DD-HMC are among the most popular algorithms to simulate Wilson fermions. We present a comparison of the performance of the two algorithms for realistic
quark masses and l...
A comparison of Hořava-Lifshitz gravity and Einstein gravity through thin-shell wormhole construction

2010/12/20
In this paper we have constructed a new class of thin-shell wormholes from black holes in Hoˇrava-Lifshitz gravity. Particular emphasis is placed on those aspects that allow a comparison of Hoˇrava-Li...
The KamLAND-experiment and Soliton-like Nuclear Georeactor. Part 1. Comparison of Theory with Experiment
The KamLAND-experiment Soliton-like Nuclear Georeactor
2010/11/18
We give an alternative description of the data produced in the KamLAND experiment, assuming the existence of a natural nuclear reactor on the boundary of the liquid and solid phases of the Earth's co...
Comparison of Thermodynamic Characteristics in Quantum and Classical Approaches and Game Theory
Comparison Thermodynamic Characteristics Quantum Classical Approaches Game Theory
2010/11/11
We fix the temperature $T$ and consider mean energy and entropy as two players of a game. As a result, basic formulas for the quantum mean energy and the quantum entropy are derived. We compare also t...
Transport calculations in complex materials: A comparison of the Kubo formula, the Kubo-Greenwood formula and the microscopic response method
Transport calculations complex materials Kubo-Greenwood formula microscopic response method
2010/11/18
Recently we have introduced the microscopic response method (MRM) to compute the conductivity
and Hall mobility for complex system with topological and thermal disorder, which is more
convenient tha...
Quantum correlation: Comparison of measures with geometry and mutual information
Quantum correlation Comparison measures geometry mutual information
2010/11/5
Two measures for quantum correlations were proposed recently from a geometric perspective [Phys. Rev. Lett. 104, 080501 (2010); e-print arXiv:1004.0190]. We prove the the equivalence of the two geomet...
We propose a scheme for unambiguous state comparison (USC) of two unknown squeezed vacuum states of an electromagnetic field. Our setup is based on linear optical elements and photon-number detectors,...
Comparison of the hydrodynamic and Dirac models of the dispersion interaction between graphene and H, He${}^{\ast}$, or Na atoms
