Reply to Comment on "Critical analysis of a variational method used to describe molecular electron transport"
Ioan Baldea, Horst Köppel
We show that the failure of the Delaney-Greer (DG) variational ansatz for transport demonstrated by us in Phys.\ Rev.\ B {\bf 80}, 165301 (2009) (I) is not related to an unsuitable…

Critical analysis of a variational method used to describe the molecular electron transport
Ioan Baldea, Horst Köppel
In a recent paper [I.\ Bâldea and H.\ Köppel, \prb {\bf 78}, 115315 (2008)], we showed that a variational approach [P.\ Delaney and J.\ C.\ Greer, \prl {\bf 93}, 036805 (2004)] pro…

Transition voltage spectroscopy: a challenge for vacuum tunneling models at nanoscale
Ioan Baldea, Horst Koppel
Several studies on the transition voltage () are based on calculations of the tunneling current within the Simmons model. In this paper devoted to vacuum nano-junctions, we co…
