Pauli Blockade of Tunable Two-Electron Spin and Valley States in Graphene Quantum Dots
Chuyao Tong, Annika Kurzmann, Rebekka Garreis +9
Pauli blockade mechanisms -- whereby carrier transport through quantum dots is blocked due to selection rules even when energetically allowed -- are a direct manifestation of the P…
Kondo effect and spin-orbit coupling in graphene quantum dots
Annika Kurzmann, Yaakov Kleeorin, Chuyao Tong +12
The Kondo effect is a cornerstone in the study of strongly correlated fermions. The coherent exchange coupling of conduction electrons to local magnetic moments gives rise to a Kon…
Shell Filling and Trigonal Warping in Graphene Quantum Dots
Rebekka Garreis, Angelika Knothe, Chuyao Tong +8
Transport measurements through a few-electron circular quantum dot in bilayer graphene display bunching of the conductance resonances in groups of four, eight and twelve. This is i…
Tunable valley splitting and bipolar operation in graphene quantum dots
Chuyao Tong, Rebekka Garreis, Angelika Knothe +8
Quantum states in graphene are four-fold degenerate: two fold in spins, and two fold in valleys.Both degrees of freedom can be utilized for qubit preparations. In our bilayer graph…
Gap Opening in Twisted Double Bilayer Graphene by Crystal fields
Peter Rickhaus, Giulia Zheng, Jose L. Lado +12
Crystal fields occur due to a potential difference between chemically different atomic species. In Van-der-Waals heterostructures such fields are naturally present perpendicular to…
Tunable Valley Splitting due to Topological Orbital Magnetic Moment in Bilayer Graphene Quantum Point Contacts
Yongjin Lee, Angelika Knothe, Hiske Overweg +10
In multivalley semiconductors, the valley degree of freedom can be potentially used to store, manipulate and read quantum information, but its control remains challenging. The vall…
