Brock, Casey Neil (2019-05-20)Department: Interdisciplinary Materials ScienceIn principle, the properties of materials are determined by the behavior of electrons. Therefore quantum mechanical electronic structure calculations play a critical role in materials modeling. These calculations owe much ...

Uzelac, Ilija (2012-12-12)Department: PhysicsDisruption of the normal heart rhythm can lead to a chaotic cardiac dynamic driven by the multiple scroll waves. If ventricular fibrillation (VF) develops, the cardiac intrinsic control system is unable to terminate it, ...
-
Deepchand, Vimal (2010-03-23)Department: PhysicsWe report the observation of coherent acoustic phonon oscillations in GaSb(20 nm)/GaAs near the band gap of GaAs at room temperature. A photogenerated longitudinal acoustic phonon wave travels from the top surface of GaSb ...
-
Crochet, Jared John (2007-12-31)Department: Materials Science and EngineeringA study on the dynamics and nature of the processes leading to the redistribution of energy and charge after photoexcitation of single-wall carbon nanotubes is presented. Ultrafast as well as continuous wave spectroscopies ...

Warnick, Keith Hyrum (2013-12-13)Department: PhysicsDensity functional theory (DFT) is a landmark development in theoretical condensed matter physics that continues to be a powerful tool for exploring the behavior and properties of matter at the atomic scale. My work has ...
-
French, William Randal (2013-04-09)Department: Chemical EngineeringMolecular electronics (ME) is an emerging field with the potential to miniaturize electronic devices beyond what is possible with current top-down approaches. In ME, molecular sized building blocks self-assemble together ...
-
Yirdaw, Robel Birru (2012-07-11)Department: PhysicsProteins, as intrinsically flexible molecules, exhibit internal motions at equilibrium. In general, the internal motions consist of changes in the three dimensional coordinates of the constituent atoms. These motions are ...
-
Pigg, David Allen (2012-07-26)Department: PhysicsI present proof-of-principle applications of time-dependent coupled-cluster theory in the framework of nuclear physics, demonstrating that both energy and observables that commute with the Hamiltonian are conserved within ...
-
Chong, Fan Fei (2014-06-09)Department: MathematicsGeneralizing E-theory for C*-algebras of A. Connes and N. Higson, we defined E-theory for Lp algebras - a bivariant K-theory for closed algebra of bounded linear operators on some Lp(µ) space. We showed that our theory has ...
-
Jarrahi, Zeynab (2016-06-30)Department: PhysicsGraphene, the two dimensional allotrope of the carbon family, exhibits extremely high electron mobility, thermal conductivity and fascinating ultrafast carrier-carrier and carrier-phonons interactions. However, being merely ...
