Geometric interference in a high-mobility graphene annulus p-n junction device
Son T. Le, Albert F. Rigosi, Joseph A. Hagmann +3
The emergence of interference is observed in the resistance of a graphene annulus pn junction device as a result of applying two separate gate voltages. The observed resistance pat…
Interaction Driven Quantum Hall Wedding cake-like Structures in Graphene Quantum Dots
Christopher Gutiérrez, Daniel Walkup, Fereshte Ghahari +7
Quantum-relativistic matter is ubiquitous in nature; however it is notoriously difficult to probe. The ease with which external electric and magnetic fields can be introduced in gr…
An On/Off Berry Phase Switch in Circular Graphene Resonators
Fereshte Ghahari, Daniel Walkup, Christopher Gutiérrez +10
The phase of a quantum state may not return to its original value after the system's parameters cycle around a closed path; instead, the wavefunction may acquire a measurable phase…
