A triple quantum dot in a single wall carbon nanotube
K. Grove-Rasmussen, H. I. Jørgensen, T. Hayashi +2
A top-gated single wall carbon nanotube is used to define three coupled quantum dots in series between two electrodes. The additional electron number on each quantum dot is control…
Pauli spin blockade in cotunneling transport through a double quantum dot
H. W. Liu, T. Fujisawa, T. Hayashi +1
We study spin correlation in a double quantum dot containing a few electrons in each dot (around 10). Clear current rectification with negative differential conductance is observed…
Coherent manipulation of electronic states in a double quantum dot
Toshiaki Hayashi, Toshimasa Fujisawa, Hai-Du Cheong +2
We investigate coherent time-evolution of charge states (pseudo-spin qubit) in a semiconductor double quantum dot. This fully-tunable qubit is manipulated with a high-speed voltage…
Quantum stochastic differential equations for boson and fermion systems -- Method of Non-Equilibrium Thermo Field Dynamics
A. E. Kobryn, T. Hayashi, T. Arimitsu
A unified canonical operator formalism for quantum stochastic differential equations, including the quantum stochastic Liouville equation and the quantum Langevin equation both of…
