Real-Time Electron Dynamics with Exact-Exchange Time-Dependent Density-Functional Theory
(American Physical Society, 2008)
The exact exchange potential in time- dependent density-functional theory is defined as an orbital functional through the time-dependent optimized effective potential (TDOEP) method. We numerically solve the TDOEP integral ...
Real-time resolution of the causality paradox of time-dependent density-functional theory
(American Physical Society, 2008)
I show that the so-called causality paradox of time-dependent density-functional theory arises from an incorrect formulation of the variational principle for the time evolution of the density. The correct formulation not ...
Electronic zero-point oscillations in the strong-interaction limit of density functional theory
(arXiv, 2008)
The exchange-correlation energy in Kohn-Sham density functional theory can be expressed exactly in terms of the change in the expectation of the electron-electron repulsion operator when, in the many- electron hamiltonian, ...
Phase Diagram of the Spin Hall Effect
(American Physical Society, 2008)
We obtain analytic formulas for the frequency-dependent spin-Hall conductivity of a two-dimensional electron gas (2DEG) in the presence of impurities, linear spin- orbit Rashba interaction, and external magnetic field ...
Pre-Service Elementary Teachers' Field Experiences in Classrooms Led by Science Specialists
(Springer Netherlands, 2008)
The purpose of this study was to examine the experiences of preservice elementary teachers in a content-specific field-based experience with elementary science specialists. Data collected from electronic discussions, ...
Preparing the Next Generation of Science Teacher Educators: A Model for Developing PCK for Teaching Science Teachers
(Springer Netherlands, 2008)
Science education doctoral programs often fail to address a critical piece—the explicit attention to the preparation of future science teacher educators. In this article, we argue that, in addition to developing skills and ...
Temperature dependence of persistent spin currents in a spin-orbit-coupled electron gas: A density-matrix approach
(American Physical Society, 2008)
We present a simple analytical method, based on the canonical density matrix, for the calculation of the equilibrium spin current as a function of temperature in a two- dimensional electron gas with both Rashba and Dresselhaus ...
Quantum Stress Focusing in Descriptive Chemistry
(American Physical Society, 2008)
We show that several important concepts of descriptive chemistry, such as atomic shells, bonding electron pairs, and lone electron pairs, may be described in terms of quantum stress focusing, i.e., the spontaneous formation ...
Absence of certain exchange driven instabilities of an electron gas at high densities
(American Physical Society, 2008)
In the high-density limit the exchange energy easily overcomes the correlation energy in both two- and three-dimensional electron liquids. It is therefore reasonable to inquire if the class of exchange driven instabilities ...
