Flux quantization

Flux Quantization


Quantization realizable

Quantization: Realizable?

  • Phase slip effect

  • Phase pinning

  • Numbers


Realization oxides

Realization: Oxides

Prof. Hans Hilgenkamp(University of Twente)


Realization graphene

Realization: Graphene


Conclusion

Conclusion

  • Double layer exciton superfluid acts as a diamagnet

  • Ring-shaped structure gives unconventional flux quantization

  • Realizable with oxides or graphene
