Relationship between electron density and effective densities of body tissues for stopping, scattering and nuclear interaction of proton and ion beams
electron density body tissues proton and ion beams
2011/9/9
In treatment planning of charged-particle radiotherapy, patient heterogeneity is normally modeled as variable-density water to best reproduce the stopping power. This water-based model would cause sub...
When effective theories predict: the inevitability of Mercury's anomalous perihelion precession
Mercury’s Orbits in Newton’s Theory perturbations
2011/8/31
If the concepts underlying Effective Theory were appreciated from the earliest days of Newtonian gravity, Le Verrier’s announcement in 1845 of the
anomalous perihelion precession of Mercury would hav...
Effective spin model for interband transport in a Wannier-Stark lattice system
Effective spin model interband transport Wannier-Stark lattice system
2010/10/29
We show that the interband dynamics in a tilted two-band Bose-Hubbard model can be reduced to an analytically accessible spin model in the case of resonant interband oscillations. This allows us to pr...
Effective Mass Dirac-Morse Problem with any kappa-value
generalized Morse potential Dirac equation Position-Dependent Mass Nikiforov- Uvarov Method Spin Symmetry Pseudospin Symmetry
2010/3/10
The Dirac-Morse problem are investigated within the framework of an approximation to the term proportional to $1/r^2$ in the view of the position-dependent mass formalism. The energy eigenvalues and c...
Effective Annealing of ZnO Thin Films Grown by Electrochemical Deposition Technique
ZnO electrochemical deposition annealing effect
2010/4/8
Wide and direct band gap ZnO thin films have been grown on conductive indium-tin-oxide (ITO) substrates by electrochemical deposition (ECD) technique using different growth parameters. High quality fi...
The Effective Charge Velocity of Spin-{1}{2} Superlattices
Heinsenberg DMRG Plateaus Luttinger liquid
2010/9/25
We calculate the spin gap of homogeneous and inhomogeneous spin chains, using the White’s density matrix renormalization group technique. We found that the spin gap is related to the ration between th...
