ABSTRACT
2, 6, 12, and 20 electron quantum dots have been studied using coupled cluster at singles and doubles level and extensive multireference coupled cluster (MRCC) method. A Fock-space version of MRCC (FSMRCC) containing single hole-particle excited determinants has been used to calculate low-lying excited states of the above system. The ionization potential and electron affinity are also calculated. The effect of correlation energy on excitation energy and charge density is shown by calculating them at the high density region (low value of density parameter rs) and at the low density region (high value of density parameter rs).

    A method for calibrating a multilayer spectrometer using α particles is presented. This spectrometer is composed of successive semiconductor Si(Li) detectors and is used for precision detection of long-range charged particles (p, d, and t) with energies of ∼100 MeV. The factors affecting...

    The conductance of the quantum point contact (QPC) has a shoulder-like anomaly below the last conductance plateau, which is called “0.7 anomaly.” By using a single QPC, we succeed in controlling the presence of the anomaly by tuning the potential for defining the QPC. We also...

    Physics considered here is the active control of a quantum system and of its decoherence by its environment. The relevance is in the quantum nature of nanoscience and how coherent optics in semiconductor quantum dots can contribute to quantum control. This article reviews: (1) The more recent...

    The self-organization of electron-hole quantum plasmas is described. It is shown that steady state equilibrium is governed by a triple curl Beltrami field which is a superposition of three Beltrami fields. The results show the possibility of creating Beltrami fields of the order of nanoscale...

    We demonstrate fast initialization of a single hole spin trapped in an InGaAs quantum dot with a fidelity F>99% and a 1/e time of ∼30 ps, by applying a magnetic field parallel to the growth direction. We show that the fidelity of the hole spin, prepared by ionization of a photo-generated...

    The authors have investigated the effects of 200 and 300 keV electron-beam irradiations on amorphization in 6H-SiC at 100 and 295 K. Amorphization is induced by the accumulation of defects produced by direct atomic displacements. Dynamic recovery of these defects during irradiation, due to...
