Understanding disorder in Silicon quantum computing platforms: Scattering mechanisms in Si/SiGe quantum wells

Yi Huang, Sankar Das Sarma

Motivated by recent experiments on Si/SiGe quantum wells with a co-design of high electron mobility and large valley splitting [B. Paquelet Wuetz, et al., Nature Communications 14,…

Interaction and coherence in 2D bilayers

Jihang Zhu, Sankar Das Sarma

In bilayer systems, the additional layer pseudospin enables the emergence of interlayer coherence (IC), which is a direct consequence of the interlayer Coulomb interaction. This st…

Symmetry breaking in zero-field two-dimensional electron bilayers

Tessa Cookmeyer, Sankar Das Sarma

We theoretically consider bilayers of two dimensional (2D) electron gases as in semiconductor quantum wells, and investigate possible spontaneous symmetry breaking transitions at l…

Monte Carlo solver and renormalization of Migdal-Eliashberg spin chain

Yang-Zhi Chou, Zhentao Wang, Sankar Das Sarma

Motivated by the recently developed classical spin model for Migdal-Eliashberg theory, we develop new numerical and analytical methods based on this spin-chain representation and a…

Engineering the Kitaev spin liquid in a quantum dot system

Tessa Cookmeyer, Sankar Das Sarma

The Kitaev model on a honeycomb lattice may provide a robust topological quantum memory platform, but finding a material that realizes the unique spin liquid phase remains a consid…

Correlated insulator in two Coulomb-coupled quantum wires

Yang-Zhi Chou, Sankar Das Sarma

Motivated by the recently discovered incompressible insulating phase in the bilayer graphene exciton experiment [arXiv:2306.16995], we study using bosonization two Coulomb-coupled…
