title: Supplementary material for `Dynamic renormalization of scalar active field theories`

description: The following folders have Jupyter notebook files that are used to obtain the results we present in Section I.1, I.2, III.B, III.C, IV.A and IV.B and Appendix C and D and Figures 9, 10, 11, 13. To calculate the graphical corrections we extensively use the Python package ``restflow'' (&lt;a href="https://github.com/us-itp4/restflow"&gt;https://github.com/us-itp4/restflow&lt;/a&gt;). Each folder has one subfolder with figures used in the notebooks.
&lt;br&gt; &lt;br&gt;
&lt;b&gt;Description of supplementary files&lt;/b&gt;
&lt;br&gt; &lt;br&gt;
1) &lt;b&gt;tutorials&lt;/b&gt;: A folder which illustrates with examples how to use the package ``restflow''. It includes: 
&lt;br&gt; &lt;br&gt;
 • &lt;code&gt;model_b_simple.ipynb&lt;/code&gt;: A pedagogical tutorial to use restflow for the graphical corrections of the Model B (for the classic case with shifted field)
&lt;br&gt;
 • &lt;code&gt;ckpz.ipynb&lt;/code&gt;: A pedagogical tutorial to use restflow for the graphical corrections of the cKPZ
&lt;br&gt;
 • &lt;code&gt;neural.ipynb&lt;/code&gt;: A pedagogical tutorial to use restflow for the graphical corrections of a neural field model. It also analyzes the flow equations with the fixed points and plots Fig.11
&lt;br&gt; &lt;br&gt;
2) &lt;b&gt;analysis&lt;/b&gt;: A folder which is used for the analysis of the Active Model B+ and the Model B with the extra cubic term. It includes:
&lt;br&gt; &lt;br&gt;
 • &lt;code&gt;model_b_noshift.ipynb&lt;/code&gt;: calculates the graphical corrections for the Model B without shifting the field (with the b model parameter) (Appendix C). It is used to plot Fig.13
&lt;br&gt;
 • &lt;code&gt;amb+_graphs.ipynb&lt;/code&gt;: calculates the graphical corrections of the Active Model B+ (Appendix D). It also calculates the graphical corrections leading to higher-order terms (Section III.C)
&lt;br&gt;
 • &lt;code&gt;amb+_noshift.ipynb&lt;/code&gt;: calculates the flow equations for the Active Model B+ without shifting the field. It also analyzes its fixed points and applies stability analysis (Section III.D.1). It optionally plots the flow equations (figure not shown in manuscript)
&lt;br&gt;
 • &lt;code&gt;amb+_shift.ipynb&lt;/code&gt;: calculates the flow equations for the Active Model B+ with shifting the field. It also analyzes its fixed points and applies stability analysis (Section III.D.2). It optionally plots the flow equations (figure not shown in manuscript)
&lt;br&gt; &lt;br&gt;
3) &lt;b&gt;simulations&lt;/b&gt;: A folder which is used for the flow equations of the modified cKPZ and for the numerical simulations of the stochastic partial differential equation using py-pde. It includes: 
&lt;br&gt; &lt;br&gt;
 • &lt;code&gt;modified_ckpz.ipynb&lt;/code&gt;: calculates the graphical corrections and analyzes the flow equations for the modified cKPZ of Section IV.A. It plots Fig.9 and simulates the stochastic partial differential equation using py-pde and plots Fig.10
&lt;br&gt;
 • &lt;code&gt;3d_4000&lt;/code&gt;: A folder of the data of the modified cKPZ using py-pde. It is used for the modified_ckpz.ipynb
