Using a time-averaged pancake-density, we compute a new substrate potential iteratively. We start with a substrate corresponding to a pancake solid at zero temperature. The self-consistent method then converges, depending on temperature, either to a lattice or a pancake liquid. Using our method, we compute the melting line for a three-dimensional pancake system with electromagnetic interactions.

Abstract

We study layered pancake systems numerically in the limit of zero Josephson coupling. We take into account the long-range nature of the pancake interaction in the c-direction, by employing the substrate model[1]: all attractive out-of-layer interactions are represented by a substrate potential, which pancakes experience in addition to the in-layer pancake repulsion. Using a time-averaged pancake-density, we compute a new substrate potential iteratively. We start with a substrate corresponding to a pancake solid at zero temperature. The self-consistent method then converges, depending on temperature, either to a lattice or a pancake liquid. Using our method, we compute the melting line for a three-dimensional pancake system with electromagnetic interactions.
