From Low-Density Neutron Matter to the Unitary Limit
T. Abe, R. Seki
Various quantities of an attractively interacting fermion system at the unitary limit are determined by extrapolating Monte Carlo results of low-density neutron matter. Smooth extr…
Lattice Calculation of Thermal Properties of Low-Density Neutron Matter with Pionless NN Effective Field Theory
T. Abe, R. Seki
Thermal properties of low-density neutron matter are investigated by determinantal quantum Monte Carlo lattice calculations on 3+1 dimensional cubic lattices. Nuclear effective fie…
Effective Field Theory of Nucleon-Nucleon Scattering on Large Discrete Lattices
Ryoichi Seki, U. van Kolck
Nuclear effective field theory is applied to the effective range expansion of S-wave nucleon-nucleon scattering on a discrete lattice. Lattice regularization is demonstrated to yie…
Mean Field Calculation of Thermal Properties of Simple Nucleon Matter on a Lattice
T. Abe, R. Seki, A. N. Kocharian
Thermal properties of single species nucleon matter are investigated assuming a simple form of the nucleon-nucleon interaction. The nucleons are placed on a cubic lattice, hopping…
Determination of Matter Surface Distribution of Neutron-rich Nuclei
Akihisa Kohama, Ryoichi Seki, Akito Arima +1
We demonstrate that the matter density distribution in the surface region is determined well by the use of the relatively low-intensity beams that become available at the upcoming…
Correlation and Finite Interaction-Range Effects in High-Energy Electron Inclusive Scattering
Akihisa Kohama, Koichi Yazaki, Ryoichi Seki
We calculate cross sections of high energy electron inclusive scattering off nuclear matter in a new and consistent formulation based on the Green's function method with the Glaube…
