Compute transition probability using Boltzmann distribution.

Description

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

Usage

1
  transitionProbability1D_R(ikBT, x, xFlip, J, H)

Arguments

ikBT

1/kB*T (Boltzmann factor)

x

1D Spin sites on the lattice.

xFlip

1D Spin sites on the lattice: after a flip.

J

Interaction strength

H

External field

Value

Returns transition probability.

  n             <- 10 # 10 spin sites
  mySites       <- genConfig1D_R(n) # Generate sites
  mySitesNew    <- flipConfig1D_R(mySites)
  # only short-range part
  transitionProbability1D_R(1.0, mySites, mySitesNew, 1.0, 0.0)
