Student Workshop on Integrability

16 Jun 2025, 08:30 → 20 Jun 2025, 18:00 Europe/Budapest

Eötvös Room, Northern Building

For materials, e.g. schedule or locations of food places, please scroll down to the bottom of the page.

We have the pleasure of inviting prospective speakers and participants to the 6th edition of the Student Workshop on Integrability. This year the workshop will take place in Budapest, Hungary. The aim of the event is to provide a space for PhD students and early-career to mid-career postdocs in the field of integrability to present and discuss their research while strengthening the connections within the integrability community.

During this years' edition, we are honoured to host three keynote speakers, Rafael Nepomechie, Katja Klobas and Andrea De Luca. For further information about the lectures see "Contributions" or the "Book of Abstracts". 

This is a event under the EU COST Action THEORY-CHALLENGES (CA22113). If you are not a member of the EU COST Action THEORY-CHALLENGES (CA22113), please don't forget to join, see

https://www.theory-challenges.eu/join-the-action

The deadline for application (and for joining the Action) is the 15th of April 2025. Invitations will be issues by the e-COST portal shortly after that. YOU NEED TO BE PART OF THE ACTION TO ATTEND!

Apart from the scientific program, the workshop should offer an opportunity to get in touch with other peer-group members. Hence, there will be many social events: A cultural trip and social nights outs.

There will be two types of contributions to the scientific program by the participants. You can either apply to give a 20 talk or you can design a poster to present it in one of the poster sessions. To do so please hand in additionally an "Abstract" in the section "Call for Abstracts". The deadline of submitting an abstract is the 15 May 2025.

There is no participation fee. However, the participants need to pay for accommodation and travel by themself. We can offer limited financial support for participants who have a limited budget. To apply for support please fill in the corresponding field in the application form.

Further, either you organize an accommodation by yourself or you request a room of our subscription to hotel rooms during the registration process. In the latter case, you would share a double room with another young researcher. Note that you still need to pay for the accommodation by yourself!

For information about the previous editions of the workshop, please see the website. For updates, you can also follow us on Facebook.

Monday 16 June

Organization: Opening

1 Quantum non-equilibrium dynamics with classical determinist circuits I

TBA

Speaker: Katja Klobas (University of Birmingham)

2 Generalised hydrodynamics of optical soliton gases: measurement of correlations

Speaker: Elias CHARNAY (University of Lille)

10:30 Coffee

3 Exact quantum state preparation I

This course is an introduction to some approaches for exactly preparing multi-qubit states on a quantum computer. In Lecture 1, we begin with a brief review of quantum circuits; we then consider the GHZ state, and its preparation in constant depth. In Lecture 2, we introduce matrix product states and sequential state preparation; we consider the example of AKLT states, and their preparation in constant depth. In Lecture 3, we consider the preparation of Dicke states and Bethe states.

Speaker: Rafael Nepomechie (University of Miami)
