lattice1DenergyNN_R: Nearest-Neighbour energy in periodic boundary conditions in 1D

Description

Given a vector of flip sites, 1s or -1s, representing up and down spins respectively, return nearest neighbour energy, applying periodic boundary conditions, i.e., cyclic. This function is a pure R implementation.

Usage

lattice1DenergyNN_R(x)

Arguments

x

1D Spin sites on the lattice

Value

Returns the nearest neighbour energy.

Examples

  n          <- 10 # 10 spin sites
  mySites    <- genConfig1D_R(n) # Generate sites
  nnEnergy <- lattice1DenergyNN(mySites)
