Transport gap engineering by contact geometry in graphene nanoribbons: Experimental and theoretical studies on artificial materials
Thomas Stegmann, John A. Franco-Villafañe, Ulrich Kuhl +2
Electron transport in small graphene nanoribbons is studied by microwave emulation experiments and tight-binding calculations. In particular, it is investigated under which conditi…
Correlation Matrix Spectra: A Tool for Detecting Non-apparent Correlations?
Soham Biswas, Francois Leyvraz, Paulino Monroy Castillero +1
It has been shown that, if a model displays long-range (power-law) spatial correlations, its equal-time correlation matrix of this model will also have a power law tail in the dist…
Lithium Adsorbtion on Polyacenes Zig-zag-edge Graphene Strips
Yenni P. Ortiz, Douglas J. Klein, Thomas H. Seligman
The effect of increased electron-density (from adsorbed Li atoms) in polyacenes and in nano-ribbons with zig-zag edge is discussed in terms of resonance theoretical considerations…
Chains of benzenes with lithium-atom adsorption: Vibrations and spontaneous symmetry breaking
Yenni P. Ortiz, Thomas Stegmann, Douglas J. Klein +1
We study effects of different configurations of adsorbates on the vibrational modes as well as symmetries of polyacenes and poly-p-phenylenes focusing on lithium atom adsorption. W…
Protecting coherence by environmental decoherence: A solvable paradigmatic model
Juan Mauricio Torres, Thomas H. Seligman
We consider a particularly simple exactly solvable model for a qubit coupled to sequentially nested environments. The purpose is to exemplify the coherence conserving effect of a c…
Microwave emulations and tight-binding calculations of transport in polyacetylene
Thomas Stegmann, John A. Franco-Villafañe, Yenni P. Ortiz +3
A novel approach to investigate the electron transport of cis- and trans-polyacetylene chains in the single-electron approximation is presented by using microwave emulation measure…
