| Abstract | Summary form only given. Along with the growing body of experimental work on semiconductor quantum dots, there have been efforts to characterize these interactions through approximation techniques. This paper presents a formulation of the Hartree-Fock approximation using the finite-difference time-domain (FDTD) method to simulate two particles in a quantum dot. The FDTD method is one of the most widely used methods in electromagnetic simulation and it has recently been applied to the simulation of the Schroedinger equation. The computational intensity of the Coulomb and exchange terms are partly circumvented by using signal-processing techniques and a two-dimensional fast Fourier transform. While the resulting simulation is computationally intense, it is well within the realm of state-of-the-art computing platforms. This technique allows for the simulation of two-electron wavepacket dynamics as well as the determination of energy eigenstates. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
