Roadmap on Advancements of the FHI-aims Software Package
Joseph W. Abbott, Carlos Mera Acosta, Alaa Akkoush +203
Electronic-structure theory is the foundation of the description of materials including multiscale modeling of their properties and functions. Obviously, without sufficient accurac…
Multiscale theory of valley splitting
Sucismita Chutia, S. N. Coppersmith, Mark Friesen
The coupling between valleys in the conduction band of a Si quantum well arises from phenomena occurring within several atoms from the interface, thus ruling out a theoretical…
Spin-Valley Kondo Effect in Multi-electron Silicon Quantum Dots
Shiueyuan Shiau, Robert Joynt
We study the spin-valley Kondo effect of a silicon quantum dot occupied by electrons, with up to four. We show that the Kondo resonance appears in the…
Valley Kondo Effect in Silicon Quantum Dots
Shiue-yuan Shiau, Sucismita Chutia, Robert Joynt
Recent progress in the fabrication of quantum dots using silicon opens the prospect of observing the Kondo effect associated with the valley degree of freedom. We compute the dot d…
Valley Splitting Theory of SiGe/Si/SiGe Quantum Wells
Mark Friesen, Sucismita Chutia, Charles Tahan +1
We present an effective mass theory for SiGe/Si/SiGe quantum wells, with an emphasis on calculating the valley splitting. The theory introduces a valley coupling parameter, ,…
Detection and measurement of the Dzyaloshinskii-Moriya interaction in double quantum dot systems
Sucismita Chutia, Mark Friesen, Robert Joynt
Spins in quantum dots can act as the qubit for quantum computation. In this context we point out that spins on neighboring dots will experience an anisotropic form of the exchange…
