TY - EJOU AU - Tsuruta, Kenji TI - Hybrid Quantum/Classical Approaches of Nano- and Meta-Materials T2 - The International Conference on Computational \& Experimental Engineering and Sciences PY - 2009 VL - 13 IS - 3 SN - 1933-2815 AB - Unique properties in artificially designed new materials are demonstrated via multiple-scale computational techniques. A density-functional/classical molecular-dynamics method is employed to investigate segregation dynamics of dopants in nanostructured ceramics/semiconductors. We also develop a classical electromagnetic simulation algorithm combining with an electronic-structure calculation for analysis on optical properties of meta-materials. We demonstrate that these novel algorithms are highly optimized for ultra-scale parallel computers. KW - DO - 10.3970/icces.2009.013.063
