Within the approach of Boltzmann kinetic equation, weinvestigated interaction between polaritons inmicrocavity. Under resonant optical excitation, thisscattering process resulted in concentration Polaritonson not only the ground state, known as Bose-EinsteinCondensation, but also a excited state. Our calculatedresults are in agreement with experimental results ofSavvidis et al.Người trình bày: Lê Nguyễn Minh Thông62. Model of Subdiffusion Within Flavin ReductaseProtein with Morse PotentialNguyễn Thị Thương, Ngô Thị Thu Phương, NgôVăn Thanh, Nguyễn Ái ViệtSome phenomenon observed in recent nanoscale singlemoleculebiophysics experiments is subdiffusion, whichlargely departs from the classical Brownian diffusiontheory. To explain this subdiffusion phenomenon, atheoretical model is formulated in the work of Kou et al2008 and the taken potential was parabolic. In this workwe investigate the Kou model with Morse potential forthe case of flavin reductase protein. By applying Morsepotential, we found a better agreement withexperimental data then using parabolic potential.Người trình bày: Nguyễn Thị ThươngIII. VẬT LÝ THỐNG KÊ, TINH THỂ KIM LOẠI, HỢP KIM63. The Pressure Dependence of EXAFS Debye-Waller Factors in CrystalsVũ Văn Hùng, Hồ Khắc Hiếu, Nguyễn Văn HùngIn present article, the pressure dependence of Debye-Waller factors in crystals have been investigated byusing statistical moment method (SMM). The presentSMM calculations indicate that the Debye-Wallerfactors of crystals decreases slightly under highpressure. Our results are also compared with othercalculations and experiment and are found to be in gooagreement with these results.Người trình bày: Hồ Khắc Hiếu64. Study of Structural Phase Transformation andMelting Temperature of Metals: PressureDependenceVũ Văn Hùng, Đặng Thanh Hải, Hoàng Văn TíchThe melting temperature and phase transformation ofmetals are studied using the statistical moment method,going the quasi-harmonic appromations. The meltingand phase transition temperatures of metals arecalculated as a function of the pressure. We discuss thepressure dependence of these temperatures of Ce, Dy,Fe, Ti metals and compare the present results with thoseof the experimental results.Người trình bày: Đặng Thanh HảiThành phố Đồng Hới (03- 06/8/2009) Trang 61/ 102 Thành phố Đồng Hới (03- 06/8/2009) Trang 62/ 102
