Edge currents in frustrated Josephson junction ladders
A. M. Marques, F. D. R. Santos, R. G. Dias
We present a numerical study of quasi-1D frustrated Josephson junction ladders with diagonal couplings and open boundary conditions, in the large capacitance limit. We derive a cor…
In-plane magnetic field vs. temperature phase diagram of a quasi-2D frustrated multiband superconductor
A. M. Marques, R. G. Dias, M. A. N. Araújo +1
Motivated by the recent discovery of iron-based superconductors, with high critical temperatures and multiple bands crossing the Fermi level, we address the conditions for the pres…
Simple approach for the two-terminal conductance through interacting clusters
A. A. Lopes, R. G. Dias
We present a new method for the determination of the two-terminal differential conductance through an interacting cluster, where one maps the interacting cluster into a non-interac…
Conductance through geometrically frustrated itinerant electronic systems
A. A. Lopes, B. A. Z. António, R. G. Dias
We study a two terminal electronic conductance through an AB ring which is an example of the family of itinerant geometrically frustrated electronic systems. These systems are…
Interacting spinless fermions in a diamond chain
A. A. Lopes, R. G. Dias
We study spinless fermions in a flux threaded AB chain taking into account nearest-neighbor Coulomb interactions. The exact diagonalization of the spinless AB chain is pres…
