               "Magnetic tuning of ballistic Josephson junctions"

Kivonatos ismertetés:
Two-dimensional structures containing superconducting phases are frequently 
used as building blocks in novel nanoscale devices. For example, the long-range
correlation related to the presence of the Cooper pairs is a key ingredient 
for the realization of quantum entanglement necessary in quantum computing 
implementations. Motivated by recent experimental works, we studied the 
Josephson effect in ballistic superconductor-monolayer graphene-superconductor 
(SGS) junctions. In my talk I will show that a magnetic field can be used to 
tune the the physical properties of the SGS junctions. I will also describe 
a novel theoretical approach developed by our group and used to model 
transport processes in these devices.
