Dear Psi-k Community,

Registration is now open at https://www.psik2025.net/registration for Psi-k 2025, which will take place in Lausanne from 25-28 August.

As most of you already know, this is the largest event worldwide in electronic-structure simulations and it is only held every five years. With more than 1200 participants attending the last edition, the conference is returning to Lausanne this year.

This year's conference promises to be one of the most exciting and defining events in the field. There will be 35 thematic symposia in six parallel sessions, six plenary talks, over 120 invited talks, and space for around 200 contributed talks. Importantly, these contributed talks will be chosen by the organisers of the respective symposia from the abstracts received by 31 May.

The deadline for early-bird registration is 31 May; you can register now and submit a single abstract either at the same time or later (but by 31 May to be considered for a contributed talk, or by 30 June to present a poster).

Thanks to the generous support from our sponsors, we have been able to maintain the same registration fees as in 2022. The fee includes refreshments during coffee breaks, lunch on three days, the option to attend our Gala event, and supervised childcare. We will also be offering fellowships to support scientists from under-represented groups, those based in Africa and those who are refugees.

All information -- including the programme and accommodation options – is available at https://www.psik2025.net/. In particular, we recommend booking accommodation as early as possible.

We look forward very much to a successful Psi-k 2025, and to seeing you all in Lausanne!
