(Vanderbilt University. Dept. of Physics and Astronomy, 2012-04)Cosmic microwave background (CMB) observations suggest the possibility of an extra dark radiation component, while the current evidence from big bang nucleosynthesis (BBN) is more ambiguous. Dark radiation from a decaying ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-04)Rotation period distributions for older open clusters are difficult to obtain because of the general scarcity of clusters with ages greater than 200 Myr, as well as the challenge of measuring rotation periods for less ...
-
(Vanderbilt University. Dept. of Physics and Astronomy, 2012-05-04)Density functional theory is utilized in real-time, real-space simulations of LEED measurements and attosecond electron scattering. For LEED measurements, we find that our simulation results agree well with experimental ...

(Vanderbilt University. Department of Physics and Astronomy, 2013-04-22)We demonstrate the acceleration obtained from using GPU/CPU hybrid clusters and supercomputers for N-body simulations of gravity based in part on the author's new code development. Validation tests are shown for ...

(Vanderbilt University. Department of Physics and Astronomy, 2013-04-22)Time Dependent Density Functional Theory is used to probe the structure of matter. Coulomb explosion of small hydrocarbons driven by strong laser pulses and electron holography of molecules are studied in a theoretical ...
-
(Vanderbilt University. Department of Physics and Astronomy, 2013-04-22)In 2012, the collaboration overseeing the Daya Bay Reactor Neutrino Experiment announced results which determined the magnitude of the mixing angle \theta_{13} with unprecedented precision. However, no attempt was made in ...

(Vanderbilt University. Department of Physics and Astronomy, 2013-04-22)Electron microscopy has been the recent subject of molecular imaging due to the strength of the electrons' interaction with the target molecule making for a detailed pattern at a small scale.[1] To achieve the best 4D ...
