Talk Abstract: At present there is a significant need to model and understand dynamic quantum transport in realistic nanoscale devices including non-idealities e.g. due to scattering to ultimately guide the development of novel quantum devices operating at terahertz frequencies, even exploiting plasmonic waves for THz sensing and emission. In approaching this goal, in this talk I provide a broader introduction into the field of the modeling of nanoscale materials and devices. Particular attention is put on the transport problem under time-dependent biases and on the challenges to solve it as various physical aspects need to be simultaneously captured by a suitable model, some of which are 1) the handling the quantum mechanics of transport of open systems including the non-equilibrium physics under finite bias, 2) the complex dielectric environment typical for realistic devices, and 3) most importantly the self-consistent, dynamic coupling of the space-dependent AC charge and potential; the latter being essential to capture the plasmonic response of the system, in general.
Biographical Sketch: Diego Kienle received his PhD from the Research Center Jülich and the University of Saarland, Germany, in theoretical physics. After postdoctoral appointments with the Electrical and Computer Engineering Department at Purdue University and the Material Science Department at Sandia National Laboratories in California, he is currently with the Institute of Theoretical Physics at the University of Bayreuth. His research interest are in the theory, modeling, and simulation of AC quantum electronic transport in nanoscale materials and devices with focus on the understanding of the quantum dynamic processes in low-dimensional materials and their potential application in solid-state based terahertz devices. His past research interest are in the theory and modeling of complex fluids by means of Brownian dynamics with focus on many-body hydrodynamic interaction effects in diluted polymer solutions.
