Abstract:
Determining the quantum ballistic conductance of a nanosystem has
become of primary interest in recent years for the promise of novel
technological applications for nanoscale quantum electronic
devices. In particular, on the theoretical side, a fully first
principle theory of electronic transport is highly desirable. In this
talk I will discuss recent advances in the development of efficient
techniques to compute quantum conductance from first principles and
show examples of prototypical applications, ranging from atomic chains
to carbon nanotubes and nanotube assemblies.
