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…
Efficient quantum transport in disordered interacting many-body networks
Adrian Ortega, Thomas Stegmann, Luis Benet
The coherent transport of fermions in disordered networks of single-particle states connected by -body interactions is studied. These networks are modeled by embedded Ga…
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…
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…
