Searches for groundstate charges and spin configurations are performed with varying the sizes of dots and the number of electrons. For a two-electron system, a standout difference between the configurations with and without counting correlation energy is demonstrated. The emergence and melting of Wigner-molecule-like structures arising from the interplay between the kinetic energy and Coulombic interaction energy are described. Electron-electron correlation energies and addition energy spectra are calculated, and special electron numbers related to peculiar effects of the square well are extracted."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380004236540684289","@type":"Researcher","foaf:name":[{"@value":"Hidekazu Goto"}]},{"@id":"https://cir.nii.ac.jp/crid/1380004236540684288","@type":"Researcher","foaf:name":[{"@value":"Kikuji Hirose"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"15334880"}],"prism:publicationName":[{"@value":"Journal of Nanoscience and Nanotechnology"}],"dc:publisher":[{"@value":"American Scientific Publishers"}],"prism:publicationDate":"2011-04-01","prism:volume":"11","prism:number":"4","prism:startingPage":"2997","prism:endingPage":"3004"},"reviewed":"false","createdAt":"2011-03-14","modifiedAt":"2011-03-14","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=Electron%20Transport","dc:title":"Electron Transport"},{"@id":"https://cir.nii.ac.jp/all?q=Energy%20Transfer","dc:title":"Energy Transfer"},{"@id":"https://cir.nii.ac.jp/all?q=Quantum%20Dots","dc:title":"Quantum Dots"},{"@id":"https://cir.nii.ac.jp/all?q=Thermodynamics","dc:title":"Thermodynamics"},{"@id":"https://cir.nii.ac.jp/all?q=Computer%20Simulation","dc:title":"Computer Simulation"},{"@id":"https://cir.nii.ac.jp/all?q=Electrons","dc:title":"Electrons"},{"@id":"https://cir.nii.ac.jp/all?q=Models,%20Theoretical","dc:title":"Models, Theoretical"}],"project":[{"@id":"https://cir.nii.ac.jp/crid/1040000782055171200","@type":"Project","projectIdentifier":[{"@type":"KAKEN","@value":"20710078"},{"@type":"JGN","@value":"JP20710078"},{"@type":"URI","@value":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-20710078/"}],"notation":[{"@language":"ja","@value":"第一原理量子輸送計算による高機能界面ナノ構造の設計"},{"@language":"en","@value":"Computational design of functional nanoscale interface using first-principles calculation"}]},{"@id":"https://cir.nii.ac.jp/crid/1040000782070823296","@type":"Project","projectIdentifier":[{"@type":"KAKEN","@value":"21360063"},{"@type":"JGN","@value":"JP21360063"},{"@type":"URI","@value":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-21360063/"}],"notation":[{"@language":"ja","@value":"電子輸送シミュレーションによるナノ構造電極のデザインと電気化学プロセスへの応用"},{"@language":"en","@value":"Design of nano-scale electrodes and its applications to electrochemical processing"}]},{"@id":"https://cir.nii.ac.jp/crid/1040000782101478144","@type":"Project","projectIdentifier":[{"@type":"KAKEN","@value":"22104008"},{"@type":"JGN","@value":"JP22104008"},{"@type":"URI","@value":"https://kaken.nii.ac.jp/grant/KAKENHI-PLANNED-22104008/"}],"notation":[{"@language":"ja","@value":"プロトン・ミューオンで探る新物性と量子ダイナミクス"},{"@language":"en","@value":"New properties of materials probed by proton and muon, and their quantum dynamics"}]},{"@id":"https://cir.nii.ac.jp/crid/1040282257053473920","@type":"Project","projectIdentifier":[{"@type":"KAKEN","@value":"21510133"},{"@type":"JGN","@value":"JP21510133"},{"@type":"URI","@value":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-21510133/"}],"notation":[{"@language":"ja","@value":"ナノ構造体電気伝導特性シミュレーションプログラムの開発と低消費電力回路の設計"},{"@language":"en","@value":"Development of Nano-device simulator and application to low-power circuit"}]}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360004236791358080","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Essentially exact ground-state calculations by superpositions of nonorthogonal Slater determinants"}]},{"@id":"https://cir.nii.ac.jp/crid/1360567181984256512","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Electron–electron correlation energy calculations by superposition of nonorthogonal Slater determinants"}]},{"@id":"https://cir.nii.ac.jp/crid/1360846642373182848","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Real-space finite-difference approach for multi-body systems: path-integral renormalization group method and direct energy minimization method"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1166/jnn.2011.3924"},{"@type":"KAKEN","@value":"PRODUCT-12400352"},{"@type":"KAKEN","@value":"PRODUCT-12670289"},{"@type":"KAKEN","@value":"PRODUCT-13157612"},{"@type":"KAKEN","@value":"PRODUCT-12776915"},{"@type":"OPENAIRE","@value":"doi_dedup___::89b95c8d5ee973abbbe56bd601f849e8"},{"@type":"CROSSREF","@value":"10.1186/1556-276x-8-200_references_DOI_3lHrq0h2J2AbiBF7hKbhcEL7zrV"},{"@type":"CROSSREF","@value":"10.1088/0953-8984/23/43/434001_references_DOI_3lHrq0h2J2AbiBF7hKbhcEL7zrV"},{"@type":"CROSSREF","@value":"10.1016/j.cap.2012.04.003_references_DOI_3lHrq0h2J2AbiBF7hKbhcEL7zrV"}]}
