Abstract
We study the superconductor to insulator transition at zero temperature in a
Josephson-junction array model on a honeycomb lattice with f flux quantum per
plaquette. The path integral representation of the model corresponds to a (2 + 1)-dimensional classical model, which is
used to investigate the critical behavior by extensive Monte Carlo simulations on large
system sizes. In contrast to the model on a square lattice, the transition is found to be
first order for f = 1 /
3 and…

Observations provide strong evidence that the bosonic SIT in thin films is a Mott transition driven by Coulomb interactions that are screened by virtual quasiparticle excitations, which distinguishes these SITs from those in microfabricated Josephson Junction arrays, cold atom systems, and likely in high temperature superconductors with nodes in their quasipping states.
