The neutron-proton mass difference is calculated in the electromagnetically gauged chiral solitonic bag model, with explicit isospin breaking. There are two types of contributions. First is the electromagnetic self-energy which does not get any contribution from inside the bag. The purely Skyrmionic outside and quark-Skyrmion interference contributions are both negative but very small. The main contribution comes from the explicit isospin-breaking part. This is computed by using a multireflection expansion for the bag Green’s functions. The result is 1.30 MeV for a bag size of 0.67 F.

Density functional theory investigation of TiO2 anatase nanosheets Sayın, Ceren Sibel; Toffoli, Hande; Department of Physics (2009) In this thesis, the electronic properties of nanosheets derived from TiO2 anatase structure which acts as a photocatalyst, are investigated using the density functional theory. We examine bulk constrained properties of the nanosheets derived from the (001) surface and obtain their optimized geometries. We investigate properties of lepidocrocite-type TiO2 nanosheets and nanotubes of different sizes formed by rolling the lepidocrocite nanosheets. We show that the stability and the band gaps of the considered ...
Atomic chains and lattice vibration characteristics in A2IIIB3VI compounds with tetrahedral coordination of atoms Hasanlı, Nızamı; Khomutova, M.D. (Springer Science and Business Media LLC, 1977-04-01) On the basis of the presence of atomic chains in A2 IIIB3 VI compounds having zincblende defect structure, a linear-chain model is used to calculate the lattice vibration frequencies. The agreement of the calculated and experimental frequencies is an indication of the applicability of the model and enables one to determine the motion of various atoms during the corresponding vibrations.
Phenomenological approaches on the Nd3+ doped ferroelectric LaBGeO5 Kara, N.; Kiraci, A.; Yurtseven, Hasan Hamit (2021-02-01) Two phenomenological models, namely the compressible Ising model and Landau model, have been used to analyze the specific heat and the dielectric constant data, respectively for the pure and Nd3+ doped LaBGeO5 (LBG) crystals. The critical exponent of the specific heat was extracted in both ferroelectric and paraelectric phases of the crystals studied here within the temperature intervals of [T - T-C vertical bar < 4 K. The extracted values of the critical exponent were then used to predict some thermodynami...
Neutron electric form factor at large momentum transfer Tomasi-Gustafsson, E; Rekalo, MP (IOP Publishing, 2001-07-01) Based on the recent, high-precision data for elastic electron scattering from protons and deuterons, at relatively large momentum transfer Q(2), we determine the neutron electric form factor up to Q(2) = 3.5 GeV2. The values obtained from the data ( in the framework of the nonrelativistic impulse approximation) are larger than commonly assumed and are in good agreement with the Gari-Krumpelmann parametrization of the nucleon electromagnetic form factors.
Strain gradient crystal plasticity: thermodynamics and implementation Yalçınkaya, Tuncay (Springer, 2016-01-01) This chapter studies the thermodynamical consistency and the finite element implementation aspects of a rate-dependent nonlocal (strain gradient) crystal plasticity model, which is used to address the modeling of the size-dependent behavior of polycrystalline metallic materials. The possibilities and required updates for the simulation of dislocation microstructure evolution, grain boundary-dislocation interaction mechanisms, and localization leading to necking and fracture phenomena are shortly discussed a...
