lattice1DenergyNN: 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 calls the C function 'lattice1DenergyNN'.

Usage

lattice1DenergyNN(x)

Arguments

x

1D Spin sites on the lattice

Value

Returns the nearest neighbour energy.

Examples

  n          <- 10 # 10 spin sites
  mySites    <- genConfig1D(n) # Generate sites
  # now flip 
  mySitesNew <- lattice1DenergyNN(mySites)
