Resonant energy transfer in electron-driven proton pumps
(WILEY-VCH Verlag, 2008-01)
We examine proton and electron transport in living cell membranes and show that the Coulomb interaction leads to a resonant energy transfer, from the electrons to protons during their simultaneous tunnelings, which allows ...
Fabrication and optical properties of nano-structured semipolar InGaN/GaN quantum wells on c-plane GaN template
(WILEY-VCH Verlag, 2008-05)
High density self-assembled nanostructured semipolar (NSSP) GaN pyramids are fabricated based on c-plane GaN template by in situ silane treatment followed by high temperature treatment. Semipolar InGaN/GaN multiple ...
Coherent Ultrafast Optical Manipulations of Semiconductor Quantum Dots for Quantum Computation.
(2008)
Coherent optically driven semiconductor quantum dot systems are proposed for the implementation of quantum information processing devices. Fundamental quantum computation units, the quantum bits (qubits), are realized and ...
X-Ray and Electron Generation in the relativistic Lambda-cubed Regime.
(2008)
Over the last two decades, laser-plasma interactions at relativistic intensities have been carried out using large laser facilities producing at least several hundred
millijoule pulses at a repetition rate of 10 Hz or ...
Phenomenology of Hidden Sector Physics.
(2008)
The existence of a hidden sector, composed of Standard Model (SM) singlets and the interactions between them, is well-motivated by many beyond-the-SM theories, such as GUT theories, string-inspired models and supersymmet ...
Ultrafast Dynamics of Folded Acoustic Phonons from Semiconductor Superlattices.
(2008)
There is great interest in the coherent control of short-wavelength acoustic phonons using ultrafast laser pulses for applications such as imaging and energy transport. Metallic layers have been used extensively as optical ...
Detection and Control of Individual Trapped Ions and Neutral Atoms.
(2008)
Significant interest and effort have been devoted to using quantum mechanics in order to perform quantum computations or model quantum mechanical systems. Using trapped atomic ions as the building block for a quantum ...
Precision Neutron Polarimetry and a Measurement of Parity Violating Asymmetry in N-P Capture.
(2008)
This dissertation describes developments and applications that advance the utility of polarized neutrons in fundamental nuclear physics applications including study of the hadronic weak interaction in nuclei and beta decay. ...
The Search for Exotic Baryons at the HERMES Experiment.
(2008)
One of the interesting questions of Quantum Chromodynamics, the theory that governs the interactions between quarks and gluons, has been whether it is possible to observe hadrons which can not be explained as a combination ...
Liquid State Physics of the MgO-SiO2 System at Deep Mantle Pressures.
(2008)
As the primary medium through which planetary differentiation occurs, silicate liquids are key in the study of the thermal and chemical evolution of Earth. First principles molecular dynamics simulations were used to study ...
