The data results from the output of numerical simulations 
of Lindblad quantum master equations based on exact diagonalization and 
quantum typicality techniques, and time-evolving block decimation, including 
the stochastic unraveling of the Lindblad equation into quantum trajectories. 
The applied methods are described in more detail in the publication, where we 
also provide helpful references. 

The data was generated by Tjark Heitmann, Fengping Jin, Sourav Nandy, and Robin 
Steinigeweg

The figures Fig1 - Fig4 and FigS1 - FigS4 can be found in the folder /figures. 
There, we also provide plot scripts Fig*.gp which can be used to recreate the 
graphics.  Assuming that gnuplot and latex are installed, the plot script can 
be executed using "./gpscript.sh Fig2" in a command line, where we here used 
the plot script for Figure 2 as an example. Note that the command does not 
include the ending ".gp".  

The plotscripts *.gp also reveal which datafiles are used for each figure. The 
raw data can be found in the folder /plotdata.

Data is provided mostly in plain text (.dat) format, with 
data being ordered in multiple columns. For example, often the first 
column indicates the time t, while the second column contains the value of the 
studied observable at time t.
