Research projects
We study electron transport in solid-state systems, nanotubes,
molecular wires and other molecular systems. The studied phenomena
cover photo-excitation, ac/dc conductivity, hot-electron ultrafast
dynamics, tunneling and relaxation. We use ab-initio data for
the electronic structures and describe the transport by various
techniques, including density matrix and nonequilibrium Green
functions.
We have investigated a number of effects in C and BN nanotubes. In particular, current injection by one or two laser beams, and by friction in liquids, polarizability and piezoelectricity, image states, nanotube spinning and coalescent welding. We are also looking into possible applications of these and other systems in biology. Recently, we have also studied adiabatic complete passage techniques in molecular systems. We have discovered the possibility of performing optically enantio-selective switching, formulated an analytic solution of the non-degenerate quantum control problem and described new quantum coding machines. |
