Two methods for computing the entropy of hard-sphere systems using a spherical tether model are explored, which allow efficient use event-driven molecular-dynamics simulations. An intuitive derivation is given, relates rate particle collisions, either between two particles or and its respective tether, to an associated hypersurface area, bounds system’s accessible configurational phase space. I...
A bstract We derive analytic expansions for the finite-volume energies of weakly-interacting two-particle systems, using general relations between scattering amplitudes and derived by Lüscher others. The hold ground excited states with both zero non-zero total momentum in frame. number instructive aspects arise derivation, including role accidental degeneracies importance defining a power-count...
In 2000–2001 Ulysses passed from the south to the north polar regions of the Sun in the inner heliosphere, providing a snapshot of the latitudinal structure of cosmic ray modulation and solar energetic particle populations during a period near solar maximum. Observations from the COSPIN suite of energetic charged particle telescopes show that latitude variations in the cosmic ray intensity in t...
Recent development in particle-particle random phase approximation (pp-RPA) broadens the perspective on ground state correlation energies [H. van Aggelen, Y. Yang, and W. Yang, Phys. Rev. A 88, 030501 (2013), Y. Yang, H. van Aggelen, S. N. Steinmann, D. Peng, and W. Yang, J. Chem. Phys. 139, 174110 (2013); D. Peng, S. N. Steinmann, H. van Aggelen, and W. Yang, J. Chem. Phys. 139, 104112 (2013)]...
Radiotherapy using various beams is one of the methods for treating cancer, Hadrons used to treat cancers that are near critical organs. The most important part of the cell that is damage by ionizing radiation is DNA. In this study, damages induced in the genetic material of living cells (DNA) defined by the atomic model from the protein data bank (PDB) have been studied by radiati...
