Electron-hole puddles in the absence of charged impurities
Marco Gibertini, Andrea Tomadin, Francisco Guinea +2
It is widely believed that carrier-density inhomogeneities ("electron-hole puddles") in single-layer graphene on a substrate like quartz are due to charged impurities located close…
Local density of states in metal - topological superconductor hybrid systems
Marco Gibertini, Fabio Taddei, Marco Polini +1
We study by means of the recursive Green's function technique the local density-of-states of (finite and semi-infinite) multi-band spin-orbit coupled semiconducting nanowires in pr…
Josephson current in a four terminal superconductor - exciton condensate - superconductor system
Sebastiano Peotta, Marco Gibertini, Fabrizio Dolcini +5
We investigate the transport properties of a bilayer exciton condensate that is contacted by four superconducting leads. We focus on the equilibrium regime and investigate how the…
Two-dimensional Mott-Hubbard electrons in an artificial honeycomb lattice
A. Singha, M. Gibertini, B. Karmakar +8
Electrons in artificial lattices enable explorations of the impact of repulsive Coulomb interactions in a tunable system. We have trapped two-dimensional electrons belonging to a g…
