Notebooks


We provide notebooks for data generation and analysis

* `data_generate.ipynb` : Notebook will generate the dynamic trajectories of Ising Models with external field under
different temperatures at N=512,1024 and Metropolis/Glauber dynamics.
Parameters reads
```R
N <- c(512, 1024)
ikBT <- seq(0.5,2.0,0.025)
H <- c(1.0)
#
J <- 1.0
nstep <- 2.0e6
```
* `data_analysis.ipynb` : This will compute the approach the ergodicity
and power-law exponents. Ploting the results. Resulting data.frames are also stored.
 


Generated Data Outputs


Expected output is `ising_ergo.RData` file.
This contains all the trajectories.

Analysis Outputs


Analysis generates eps, png and csv files.
Plots are for approach to ergodicity and
power-law exponents showing
