Josephson current in graphene: the role of unconventional pairing symmetries
Jacob Linder, Annica M. Black-Schaffer, Takehito Yokoyama +2
We investigate the Josephson current in a graphene superconductor/normal/superconductor junction, where superconductivity is induced by means of the proximity effect from external…
The possibility of measuring intrinsic electronic correlations in graphene using a d-wave contact Josephson junction
Annica M. Black-Schaffer, Sebastian Doniach
While not widely recognized, electronic correlations might play an important role in graphene. Indeed, Pauling's resonance valence bond (RVB) theory for the pp-bonded planar organi…
The effect of nearest neighbor spin-singlet correlations in conventional graphene SNS Josephson junctions
Annica M. Black-Schaffer, Sebastian Doniach
Using the self-consistent tight-binding Bogoliubov-de Gennes formalism we have studied the effect of nearest neighbor spin-singlet bond (SB) correlations on Josephson coupling and…
Self-consistent solution for proximity effect and Josephson current in ballistic graphene SNS Josephson junctions
Annica M. Black-Schaffer, Sebastian Doniach
We use a tight-binding Bogoliubov-de Gennes (BdG) formalism to self-consistently calculate the proximity effect, Josephson current, and local density of states in ballistic graphen…
Resonating valence bonds and mean-field d-wave superconductivity in graphite
Annica M. Black-Schaffer, Sebastian Doniach
We investigate the possibility of inducing superconductivity in a graphite layer by electronic correlation effects. We use a phenomenological microscopic Hamiltonian which includes…
A dynamical mean-field theory approach to superconductivity and antiferromagnetism in a strongly correlated electron system
H. Watanabe, S. Doniach
We present the results of numerical studies of superconductivity and antiferromagnetism in a strongly correlated electron system. To do this we construct a Hubbard model on a latti…
