If you use \(\mathcal{C}\mathtt{osmo}\mathcal{L}\mathtt{attice}\)

We welcome everyone to use \(\mathcal{C}\mathtt{osmo}\mathcal{L}\mathtt{attice}\) for their own projects — you can freely download it and adapt it to your needs. Whenever you use \(\mathcal{C}\mathtt{osmo}\mathcal{L}\mathtt{attice}\) in your research, no matter how much (or how little) you modify (or use) the code, and independently of which part of the code you touch (or use), please cite the basic versions of the code (namely version 1.0 & version 2.0), together with our lattice-cosmology technique monographs \(\mathtt{The~Art\text{-}I}\) ¹ and \(\mathtt{The~Art\text{-}II}\) ², where the basic ideas, algorithms and field-theory methods implemented in \(\mathcal{C}\mathtt{osmo}\mathcal{L}\mathtt{attice}\) are explained.

For example, if you use only fundamental fields (i.e. scalar and/or gauge fields), you can acknowledge the code with a line like the one below. Copy the ready-to-paste LaTeX sentence, or grab the corresponding BibTeX entries.

In this work we use CosmoLattice, based on the lattice-cosmology techniques presented in The Art I & II.

Open the LaTeX or BibTeX tab to copy the entries.

In this work we use CosmoLattice~\cite{Figueroa:2021yhd,Baeza-Ballesteros:2026XYZ,Florio:2026XXX},
based on the lattice-cosmology techniques presented
in~\cite{Figueroa_2020rrl,Baeza-Ballesteros:2025tme}.

If you have added new features — new dynamics (e.g. new interactions), a new observable (e.g. a field correlator), etc. — you can also add, after the citation, a line such as:

"We have modified the module [...] so that the code can run the dynamics of [...]" or "We have added a new observable for [...]", etc.
