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 thermal transport measurement in low-dimensional materials with graphene non-local noise thermometry
(Springer Science and Business Media LLC, 2021-11-15) -
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 ... -
Electron–phonon processes of the silicon-vacancy centre in diamond
(IOP Publishing, 2015)We investigate phonon induced electronic dynamics in the ground and excited states of the negatively charged silicon-vacancy (SiV−) centre in diamond. Optical transition line widths, transition wavelength and excited state ... -
Electrophilic activity-based RNA probes reveal a self-alkylating RNA for RNA labeling
(2014)Probes that form covalent bonds with RNA molecules based on their chemical reactivity would advance our ability to study the transcriptome. We developed a set of electrophilic activity-based RNA probes designed to react ... -
An electrophysiological assessment of distractor suppression in visual search tasks
(Wiley-Blackwell, 2009)We investigated whether the N2pc is unequivocally linked to distractor-suppression mechanisms, as is commonly assumed. According to the distractor-suppression account of the N2pc, no suppression, and thus no N2pc, should ... -
Electrophysiological Correlates of Spatial Orienting Towards Angry Faces: A Source Localization Study
(Pergamon Press, 2008)The goal of this study was to examine behavioral and electrophysiological correlates of involuntary orienting toward rapidly presented angry faces in non-anxious, healthy adults using a dot-probe task in conjunction with ... -
Electrophysiological Correlates of the Autobiographical Implicit Association Test (aIAT): Response Conflict and Conflict Resolution
(Frontiers Media S.A., 2016)The autobiographical IAT (aIAT) is an implicit behavioral instrument that can detect autobiographical memories encoded in an individual's mind by measuring how quickly this person can categorize and associate sentences ... -
Electrophysiological Dissociation of Picture Versus Word Encoding: The Distinctiveness Heuristic as a Retrieval Orientation
(Massachusetts Institute of Technology Press, 2005)Event-related potentials (ERPs) were used to investigate the neural processes underlying the distinctiveness heuristic— a response mode in which participants expect to remember vivid details of an experience and make ... -
Electrophysiological Evidence of Attentional Biases in Social Anxiety Disorder
(Cambridge University Press, 2009)Background: Previous studies investigating attentional biases in social anxiety disorder (SAD) have yielded mixed results. Recent event-related potential (ERP) studies using the dot-probe paradigm in non-anxious participants ... -
Electrostatic Interactions between Elongated Monomers Drive Filamentation of Drosophila Shrub, a Metazoan ESCRT-III Protein
(2016)SUMMARY The endosomal sorting complex required for transport (ESCRT) is a conserved protein complex that facilitates budding and fission of membranes. It executes a key step in many cellular events, including cytokinesis ... -
Electrostatic Localization of RNA to Protocell Membranes by Cationic Hydrophobic Peptides
(WILEY-VCH Verlag, 2015)Cooperative interactions between RNA and vesicle membranes on the prebiotic earth may have led to the emergence of primitive cells. The membrane surface offers a potential platform for the catalysis of reactions involving ... -
Electrostatic solitary waves in an electron-positron pair plasma with suprathermal electrons
(AIP Publishing, 2017)The nonlinear propagation of electrostatic solitary waves is studied in a collisionless electron-positron pair plasma consisting of adiabatic cool electrons, mobile cool positrons (or electron holes), hot suprathermal ... -
Electrostatically Doped Silicon Nanowire Arrays for Multispectral Photodetectors
(American Chemical Society (ACS), 2019-10-02)Nanowires have promising applications as photodetectors with superior ability to tune absorption with morphology. Despite their high optical absorption, the quantum efficiencies of these nanowire photodetectors remain low ... -

Electroweak symmetry breaking from dimensional deconstruction
(Elsevier BV, 2001)We propose a new class of four-dimensional theories for natural electroweak symmetry breaking, relying neither on supersymmetry nor on strong dynamics at the TeV scale. The new TeV physics is perturbative, and radiative ...
