Calibration of the Particle Density in Cellular-Automaton Models for Traffic Flow
Particle Density Traffic Flow Cellular-Automaton Models
2010/4/2
We introduce density dependence of the cell size in cellular-automaton models for traffic flow, which allows a more precise correspondence between real-world phenomena and what observed in simulation....
Entangled three-particle states in magnetic field: Periodic correlations and density matrices
quantum entanglement Wigner rotation Lorentz transformation density matrix
2010/3/10
Time evolutions of different types of entangled states of three spin-1/2 particles are studied in the presence of a constant, external magnetic field, which causes the individual spins to precess. Thi...
Uniform density static fluid sphere in higher dimensions and its universality
spacetime dimension uniform density sphere
2010/3/18
In Newtonian theory, gravity inside a constant density static sphere is independent of spacetime dimension. Interestingly this general result is also carried over to Einsteinian as well as higher orde...
Asymptotic mean density of sub-unitary ensemble
Asymptotic mean density sub-unitary ensemble
2010/4/7
The large N limit of mean spectral density for the ensemble of NxN sub-unitary matrices derived by Wei and Fyodorov (J. Phys. A: Math. Theor. 41 (2008) 50201) is calculated by a modification of the sa...
Comparison study of the charge density distribution induced by heavy ions and pulsed lasers in silicon
heavy ion pulsed laser charge density distribution
2009/12/24
Heavy ions and pulsed lasers are important means to simulate the ionization damage effects on semiconductor materials. The analytic solution of high-energy heavy ion energy loss in silicon has been ob...
A simple way to avoid metastable configurations in the density-matrix renormalization-group algorithms
spin model DMRG spin-1
2010/7/8
We use the spin-1 Heisenberg chain with periodic boundary conditions to ilustrate that the systems get stuck in metastable configurations only when the density-matrix renormalization-group algorithm s...
The Density-Dependent Correlations among Observables in Nuclear Matter and Hyperon-Rich Neutron Stars
Nuclear Matter Hyperon-Rich Neutron Stars Density-Dependent
2009/9/4
The conserving σ-ω-ρ mean-field approximation with nonlinear interactions of hadrons has been applied to examine properties of nuclear matter and hyperonic neutron stars. The nonlinear interactions th...
Time Ordering Effects on Hydrogen Zeeman-Stark Line Profiles in Low-Density Magnetized Plasmas
Time Ordering Low-Density Magnetized Plasmas Hydrogen
2009/9/4
Stark broadening of hydrogen lines is investigated in low-density magnetized plasmas, at typical conditions of magnetic fusion experiments. The role of time ordering is assessed numerically, by using ...
The Integrated Density of States for an Interacting Multiparticle Homogeneous Model and Applications to the Anderson Model
Multiparticle Homogeneous Model interacting quantum particles
2009/9/4
For a system of n interacting particles moving in the background of a “homogeneous” potential, we show that if the single particle Hamiltonian admits a density of states, so does the interacting n-par...
High-density implosion of fuel targets for laser-driven inertial confinement fusion has been intensively studied for many years. High temperature and high density of the imploded core plasmas up to 10...
The Diagnostics of Density Distribution for Dense Hot DT Plasmas Using Fast Protons
Density reconstruction Dense DT plasmas High temperature
2009/6/1
The density reconstruction for dense DT plasmas with high temperature has been studied. In the simulation of a plasma density diagnostics, the energy loss of fast protons going through the plasmas is ...
Effect of non-abrupt doping and interfacial profiles on the carrier sheet density in one-side modulation-doped GaN/AlGaN quantum wells
non-abrupt doping interfacial profiles carrier sheet density quantum wells
2010/7/5
The results of an accurate theoretical study on the effects of non-abrupt doping and interfacial profiles on the electron sheet density in one-side modulation-doped wurtzite GaN/AlGaN single quantum w...
Multi-technique equation of state for Fe2SiO4 melt and the density of Fe-bearing silicate melts from 0 to 161 GPa
Multi-technique e-bearing silicate melts
2014/4/8
We have conducted new equation of state measurements on liquid Fe2SiO4 in a
collaborative, multi-technique study. The liquid density (r), the bulk modulus (K), and its
pressure derivative (K′) were ...

Bayesian Generalized Probability Calculus for Density Matrices
generalized probability probability calculus density matrix quantum Bayes rule
2010/4/8
One of the main concepts in quantum physics is a density matrix, which is a symmetric positive definite matrix of trace one. Finite probability distributions can be seen as a special case when the den...
