Collective Coulomb Blockade in an Array of Quantum Dots: A Mott-Hubbard Approach
C. A. Stafford, S. Das Sarma
We investigate the electron addition spectrum in a class of Hubbard-like models which describe arrays of coupled quantum dots. Interdot tunneling leads to a sequence of two phase t…

Unusual low-temperature thermopower in the one-dimensional Hubbard model
C. A. Stafford
The low-temperature thermoelectric power of the repulsive-interaction one-dimensional Hubbard model is calculated using an asymptotic Bethe ansatz for holons and spinons. The compe…

Scaling theory of the Mott-Hubbard metal-insulator transition in one dimension
C. A. Stafford, A. J. Millis
We use the Bethe ansatz equations to calculate the charge stiffness of the one-dimensional repulsive-interaction Hubbard mod…
