Computer simulation studies of layered pancake systems using the substrate model
Computer simulation studies of layered pancake systems using the substrate model
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. [1] M. J. W. Dodgson, A. E. Koshelev, V. B. Geshkenbein, and G.

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. [1] M. J. W. Dodgson, A. E. Koshelev, V. B. Geshkenbein, and G.
