In this article, we calculate the strong coupling constant g among the decuplet baryons, the octet baryons and the pseudoscalar mesons in the heavy baryon chiral perturbation theory with the light-cone QCD sum rules, and study the strong decays Σ∗ → Λπ,Σπ. The numerical value of the strong coupling constant g is consistent with our previous calculation, the central values lead to small SU(3) br...

Tuning Conductance in π-σ-π Single-Molecule Wires.

While the single-molecule conductance properties of π-conjugated and σ-conjugated systems have been well-studied, little is known regarding the conductance properties of mixed σ-π backbone wires and the factors that control their transport properties. Here we utilize a scanning tunneling microscope-based break-junction technique to study a series of molecular wires with π-σ-π backbone structure...
