Theory of charge sensing in quantum-dot structures
Richard Berkovits, Felix von Oppen, Yuval Gefen
Charge sensing in quantum-dot structures is studied by an exactly solvable reduced model and numerical density-matrix renormalization group methods. Charge sensing is characterized…

Spin polarization and effective mass: a numerical study in disordered two dimensional systems
Richard Berkovits
We numerically study the magnetization of small metallic clusters. The magnetic susceptibility is enhanced for lower electronic densities due to the stronger influence of electron-…
