Quantum polyspectra for modeling and evaluating quantum transport measurements: A unifying approach to the strong and weak measurement regime
M. Sifft, A. Kurzmann, J. Kerski +6
Quantum polyspectra of up to fourth order are introduced for modeling and evaluating quantum transport measurements offering a powerful alternative to methods of the traditional fu…
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…
Internal Photo Effect from a Single Quantum Emitter
Pia Lochner, Jens Kerski, Annika Kurzmann +4
We demonstrate by time-resolved resonance fluorescence measurements on a single self-assembled quantum dot an internal photo-effect that emits electrons from the dot by an intra-ba…
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…
Coherent Jetting behind a gate-defined Channel in Bilayer Graphene
Carolin Gold, Angelika Knothe, Annika Kurzmann +6
Graphene has evolved as a platform for quantum transport that can compete with the best and cleanest semiconductor systems. Recently, many interesting local properties of carrier t…
Scanning Gate Microscopy of Localized States in a gate-defined Bilayer Graphene Channel
Carolin Gold, Annika Kurzmann, Kenji Watanabe +3
We use Scanning Gate Microscopy to demonstrate the presence of localized states arising from potential inhomogeneities in a 50nm-wide, gate-defined conducting channel in encapsulat…
Correlated electron-hole State in Twisted Double Bilayer Graphene
Peter Rickhaus, Folkert de Vries, Jihang Zhu +9
When twisted to angles near 1°, graphene multilayers provide a new window on electron correlation physics by hosting gate-tuneable strongly-correlated states, including insulators,…
