I can only encourage you of continuing with Mathematica and making the package available (though it requires much more time and documentation to make it usable by others), we are really lacking such computing tools in SFT and I think it's hindering other people to jump in and start to compute.

My goal would be to create such a package (for SFT and string amplitudes, including necessary tools for 2D CFT, moduli spaces, etc.), but I did not have time yet.

As more general packages, some people use Cadabra, and there is also the package described in hep-th/9506159 (library.wolfram.com/infocenter/I...).

I don't know anything. I did not really use computer tools for SFT, except for the paper using ML for string vertices. But it can hardly be called a package. I am not aware of packages used by other people (even privately).

Plus many other neat features (timezone-aware dates, etc.).
The main con is that very few people are using it, and people are reluctant to having one more platform.

I also find it easier to discuss several topics in parallel. Also it's open source, can be installed on the lab server (and if hosted by Zulip, the pro version is free for academia). So no problem of having messages deleted after one year or hidden after 30 days.

Zulip is way superior compared to Slack. First, it has built-in Latex (I know that Slack has plug-ins, but they are platform-dependent and don't work well on Linux) and mark-down (with code highlighting). I also like the fact that the interface is much simpler and cleaner, I feel less overwhelmed.

I started the talk with a general introduction to string field theory, before explaining how auxiliary fields can be used to reduce the order of interactions in two toy models: φ⁴ vector model, and open SFT with stubs. Then I discuss speculations on how things could work for closed SFT.

Here are two Bengali recipes:

If you grab Vegan Richa's book, check the sindhi mung dal, masoor dal tadka and Kashmiri dals.

I am also renovating a farm in @lamayenne.bsky.social (between #Laval and #Vitré), with the (long-term) goal of setting up an autonomous site with various projects of agroforestry, permaculture, animal shelter, and non-profit third place hosting scientific and cultural events.

During my spare time, I cook Asian vegan food (notably Indian), read fantasy and science-fiction, and practice #HEMA (historical European martial arts = medieval fencing). My favorite weapons: German longsword, sword and buckler and Destreza.
January 27, 2025 at 8:02 PM
I am also interested in philosophy and ethics, especially through Buddhism, and how to make our society better and fairer for everyone such that all beings can have a happier life.

During the last few months, I started to work on benchmarks for quantum computing, with a focus on Rydberg QPUs (for example, from Pasqal and @queracomputing.bsky.social). I am also participating to European (CEN) and international (ISO) committees on standardization of quantum technologies.

My research spans several directions, including string theory, black holes, quantum field theory and simulations. One recent highlight is how machine learning can be used to solve mathematical problems in physics, but also how physics can help to understand AI.

Indian dals are pretty easy to make vegan, and they have a lot of lentils/beans (along with being very tasty), though I cannot quantify in grams.

Thanks! I will have a look
