Electron-hole asymmetric integer and fractional quantum Hall effect in bilayer graphene
(American Association for the Advancement of Science (AAAS), 2014)The nature of fractional quantum Hall (FQH) states is determined by the interplay between the Coulomb interaction and the symmetries of the system. The unique combination of spin, valley, and orbital degeneracies in bilayer ... -
Electron-phonon interaction in ultrasmall-radius carbon nanotubes
(American Physical Society (APS), 2005)We perform analysis of the band structure, phonon dispersion, and electron-phonon interactions in three types of small-radius carbon nanotubes. We find that the s5,5d nanotube can be described well by the zonefolding method ... -
Electronic Density of States of Atomically Resolved Single-Walled Carbon Nanotubes: Van Hove Singularities and End States
(American Physical Society, 1999)The electronic densities of states of atomically resolved single-walled carbon nanotubes have been investigated using scanning tunneling microscopy. Peaks in the density of states due to the one-dimensional nanotube band ... -
Electronic dura mater for long-term multimodal neural interfaces
(American Association for the Advancement of Science (AAAS), 2015)The mechanical mismatch between soft neural tissues and stiff neural implants hinders the long-term performance of implantable neuroprostheses. Here, we designed and fabricated soft neural implants with the shape and ... -
Electronic Patient-Physician Communication: Problems and Promise
(American College of Physicians, 1998)A critical mass of Internet users will soon enable wide diffusion of electronic communication within medical practice. E-mail between physicians and patients offers important opportunities for better communication. Linking ... -
Electronic Perturbations of Iron Dipyrrinato Complexes via Ligand β-Halogenation and meso -Fluoroarylation
(American Chemical Society (ACS), 2011)Systematic electronic variations were introduced into the monoanionic dipyrrinato ligand scaffold via halogenation of the pyrrolic β-positions and/or via the use of fluorinated aryl substituents in the ligand bridgehead ... -
Electronic properties of a cluster-based solid form of carbon: C 28 hyperdiamond

Electronic properties of mechanically induced kinks in single-walled carbon nanotubes
(AIP Publishing, 2001)We have used an atomic-force microscope tip to mechanically buckle single-walled carbon nanotubes. The resistance of the induced defects ranged from 10 to 100 k Omega and varied with the local Fermi level, as determined ... -
Electronic quasiparticles in the quantum dimer model: Density matrix renormalization group results
(American Physical Society (APS), 2016)We study a recently proposed quantum dimer model for the pseudogap metal state of the cuprates. The model contains bosonic dimers, representing a spin-singlet valence bond between a pair of electrons, and fermionic dimers, ... -
Electronic states near a quantum fluctuating point vortex in a d -wave superconductor: Dirac fermion theory
(American Physical Society, 2006)We introduce a simple model of the low-energy electronic states in the vicinity of a vortex undergoing quantum zero-point motion in a d-wave superconductor. The vortex is treated as a point flux tube, carrying pi flux of ... -
Electronic Structure Calculations in Arbitrary Electrostatic Environment
(American Institute of Physics, 2012)Modeling of electronic structure of molecules in electrostatic environments is of considerable relevance for surface-enhanced spectroscopy and molecular electronics. We have developed and implemented a novel approach to ... -
Electronic structure of overstretched DNA
(American Physical Society, 2002)Minuscule molecular forces can transform DNA into a structure that is elongated by more than half its original length. We demonstrate that this pronounced conformational transition is of relevance to ongoing experimental ... -
Electronic structure of solid nitromethane: Effects of high pressure and molecular vacancies
(AIP Publishing, 2002)The combined effect of pressure and molecular vacancies on the atomic structure and electronic properties of solid nitromethane, a prototypical energetic material, is studied at zero temperature. The self-consistent charge ... -
Electronic structure theory of weakly interacting bilayers
(American Physical Society, 2016)We derive electronic structure models for weakly interacting bilayers such as graphene-graphene and graphene-hexagonal boron nitride, based on density functional theory calculations followed by Wannier transformation of ... -

Electronic Transition Moments of 6-methyl Isoxanthopterin—A Fluorescent Analogue of the Nucleic Acid Base Guanine
(Oxford University Press, 2012)Fluorescent nucleic acid base analogues are important spectroscopic tools for understanding local structure and dynamics of DNA and RNA. We studied the orientations and magnitudes of the electric dipole transition moments ... -
Electronically programmable photonic molecule
(Springer Science and Business Media LLC, 2018-12-14)Physical systems with discrete energy levels are ubiquitous in nature and are fundamental building blocks of quantum technology. Realizing controllable artificial atom- and molecule-like systems for light would enable ... -
Electron–Nuclear Interaction in \(^{13}C\) Nanotube Double Quantum Dots
(Nature Publishing Group, 2009)For coherent electron spins, hyperfine coupling to nuclei in the host material can either be a dominant source of unwanted spin decoherence or, if controlled effectively, a resource enabling storage and retrieval of quantum ...
