Mott insulating phases and magnetism of fermions in a double-well optical lattice
Xin Wang, Qi Zhou, S. Das Sarma
We theoretically investigate, using non-perturbative strong correlation techniques, Mott insulating phases and magnetic ordering of two-component fermions in a two-dimensional doub…
Quantum theory of the charge stability diagram of semiconductor double quantum dot systems
Xin Wang, Shuo Yang, S. Das Sarma
We complete our recently introduced theoretical framework treating the double quantum dot system with a generalized form of Hubbard model. The effects of all quantum parameters inv…
Hubbard model description of silicon spin qubits: charge stability diagram and tunnel coupling in Si double quantum dots
S. Das Sarma, Xin Wang, Shuo Yang
We apply the recently introduced Hubbard model approach to quantitatively describe the experimental charge stability diagram and tunnel coupling of silicon double quantum dot syste…
Generic Hubbard model description of semiconductor quantum dot spin qubits
Shuo Yang, Xin Wang, S. Das Sarma
We introduce a Hubbard model as the simple quantum generalization of the classical capacitance circuit model to study semiconductor quantum-dot spin qubits. We prove theoretically…
