Quantum coherent electronic circuits

Michael Moskalets

NTU Kharkiv Polytechnic Institute Kharkiv, Ukraine

I present a dynamical Floquet scattering theory for a mesoscopic capacitor (a quantum dot in the integer quantum Hall effect regime coupled to a single reservoir) driven by the large amplitude potential at finite frequency. Such a capacitor can serve as an on-demand deterministic source of single particles, which are well separated in time and space. Having such a source at hand one can perform quantum optics experiments but with fermions. I outline several types of electronic circuits with capacitor as a source to perform, for example, an electronic analogue of the Hanbury Brown and Twiss experiment and an electronic analogue of the Hong-Ou-Mandel experiment. In addition I discuss a proposal how to use one source to control propagation of particles emitted by the other source. briefbio Prof. Moskalets graduated from the NTU "Kharkiv Polytechnic Institute", Kharkiv, Ukraine in 1983. In 1991 he defended his PhD at the Institute for Low Temperature Physics and Engineering, Kharkiv, Ukraine. The topic of this thesis was "The spectroscopy of electron-phonon interaction in metal point and tunnel junctions with a small electron mean free path". In 2008 he received the Doctor of Science degree in theoretical physics with the thesis: "Nonstationary quantum transport in mesoscopic systems" . Currently, he is working at the NTU "Kharkiv Polytechnic Institute", Kharkiv, Ukraine. His main research interests cover subjects such as persistent currents, quantum pumping, and coherent single-electronics. The results of a fruitful and invaluable collaboration during more then 10 years with Prof. Markus Büttiker from the University of Geneva, Switzerland, formed the basis of the book "Scattering matrix approach to non-stationary quantum transport" published by Imperial College Press, London in 2011.
