Flow probe of symmetry energy in relativistic heavy-ion reactions [PDF]

, 2013
Flow observables in heavy-ion reactions at incident energies up to about 1 GeV per nucleon have been shown to be very useful for investigating the reaction dynamics and for determining the parameters of reaction models based on transport theory.

Isospin Distillation with Radial Flow: a Test of the Nuclear Symmetry Energy [PDF]

, 2007
We discuss mechanisms related to isospin transport in central collisions between neutron-rich systems at Fermi energies. A fully consistent study of the isospin distillation and expansion dynamics in two-component systems is presented in the framework of

Combining density functional theory and Monte Carlo neutron transport calculations to study the phonon density of states of UO2 up to 1675 K by inelastic neutron scattering

Physical review B, 2020
Significant advances in the use of atomistic simulation techniques, such as ab initio density functional theory and the molecular dynamics method, made it possible to predictively calculate properties of materials.

Application of the improved quasi-static coupled probability theory method to transient safety analysis of an experimental facility

Frontiers in Energy Research, 2023
The accelerator-driven sub-critical system is driven by external neutron sources, which are generated by the spallation reaction and maintain the stable operation of the sub-critical core, while the external neutron source increases the complexity of ...

Low mass binary neutron star mergers : gravitational waves and neutrino emission [PDF]

, 2016
Neutron star mergers are among the most promising sources of gravitational waves for advanced ground-based detectors. These mergers are also expected to power bright electromagnetic signals, in the form of short gamma-ray bursts, infrared/optical ...

A NOVEL COARSE-MESH METHOD APPLIED TO NEUTRON SHIELDING PROBLEMS USING THE MULTIGROUP TRANSPORT THEORY IN DISCRETE ORDINATES FORMULATIONS

Brazilian Journal of Radiation Sciences, 2021
In this paper, we propose a new deterministic numerical methodology to solve the one-dimensional linearized Boltzmann equation applied to neutron shielding problems (fixed-source), using the transport equation in the discrete ordinates formulation (SN ...

Invariant Imbedding and Neutron Transport Theory IV-Generalized Transport Theory [PDF]

Indiana University Mathematics Journal, 1959
Abstract : The aim of the paper is to extend previous results and techniques so as to include an extensive category of transport processes involving deterministic and stochastic interactions and general geometries. Characteristic func tions and probabilities as well as expected values (fluxes) are determined. (Author)

Study and Application of Multi-level Acceleration Theory for High-fidelity Neutron Transport Calculation

Yuanzineng kexue jishu, 2022
In order to solve the time-consuming problem of high-fidelity neutron transport calculation, the multi-level acceleration theory was proposed. For iterative process, the iterative acceleration was utilized to ease the computational burden.
