Describing droplet motion on surface-textured ratchet tracks with an inverted double pendulum model
(American Chemical Society, 2021-04-27)We describe the motion of a droplet on a textured ratchet track using a nonlinear resonator model. A textured ratchet track is composed of a semicircular pillar array that induces a net surface tension local gradient on a ... -
Dynamic correlation effects on the plasmon dispersion in a two-dimensional electron gas
(The American Physical Society, 2003)The charge-density oscillations (plasmons) of a low-density two-dimensional uniform electron gas are studied within the framework of finite temperature and frequency dependent (dynamic) version of Singwi, Tosi, Land, and ... -
Dynamic correlations in double-layer electron systems
(The American Physical Society, 2001)We study the effects of dynamic correlations on the ground-state properties of a double-layer two-dimensional electron gas within the quantum Singwi-Tosi-Land-Sjölander theory (STLS). The intralayer and interlayer static ... -
Enhancing higher harmonics of a tapping cantilever by excitation at a submultiple of its resonance frequency
(American Physical Society, 2005-03)In a tapping-mode atomic force microscope, the frequency spectrum of the oscillating cantilever contains higher harmonics at integer multiples of the excitation frequency. When the cantilever oscillates at its fundamental ... -
Glycosaminoglycan-Mimetic Signals Direct the Osteo/Chondrogenic Differentiation of Mesenchymal Stem Cells in a Three-Dimensional Peptide Nanofiber Extracellular Matrix Mimetic Environment
(American Chemical Society, 2016-02)Recent efforts in bioactive scaffold development focus strongly on the elucidation of complex cellular responses through the use of synthetic systems. Designing synthetic extracellular matrix (ECM) materials must be based ... -
On the stabilization of periodic orbits for discrete time chaotic systems
(Elsevier, 2005-02)In this Letter we consider the stabilization problem of unstable periodic orbits of discrete time chaotic systems. We propose a novel and simple periodic delayed feedback law and present some stability results. These results ... -
Orbital magnetization of single and double quantum dots in a tight-binding model
(American Physical Society, 2003)We calculate the orbital magnetization of single and double quantum dots coupled both by Coulomb interaction and by electron tunneling. The electronic states of the quantum dots are calculated in a tight-binding model, and ... -
Persistent currents in helical structures
(American Physical Society, 2004)The recent discovery of mesoscopic electronic structures, in particular the carbon nanotubes, made necessary an investigation of what effect a helical symmetry of the conductor (metal or semiconductor) may have on the ... -
Quantum effects of thermal conductance through atomic chains
(2001)We present a formalism for an atomic scale study of phononic heat transfer. The expression of thermal energy current can be cast in the Landauer form and incorporates the transmission coefficient explicitly. Calculation ... -
Resonant and coherent transport through Aharonov-Bohm interferometers with coupled quantum dots
(The American Physical Society, 2005)A detailed description of the tunneling processes within Aharonov-Bohm (AB) rings containing two-dimensional quantum dots is presented. We show that the electronic propagation through the interferometer is controlled by ... -
Tunneling properties of quantum dot arrays in a strong magnetic field
(The American Physical Society, 2004)We study the transport properties of coherently coupled quantum dots in the quantum Hall regime within the Landauer-Büttiker formalism which captures and explains the experimentally observed features in terms of the spectral ...
