Dynamics and Control of Quantum Many-body Systems
Recent progress in nanotechnology enables us to directly address quantum
transport of electrons in nano-devices made of metal or semiconductor.
For example, the wave nature of electrons can be controlled in electronic
interferometers ("Aharonov-Bohm rings"), while their particle
nature is accessible in quantum dots ("artificial atoms"). We
can even combine these two kinds of devices into one, where the wave-particle
duality in quantum mechanics manifests itself. The advantage of such research
field, which is called "mesoscopic physics" or "nanophysics",
lies in the controllability and the versatile degrees of freedom in the
device design. We try to understand and control various novel quantum,
many-body, and nonequilibrium effects in nano-devices in terms of the dynamical
aspects of electron transport.
