2nd international workshop on Quantum Spin Ice

Based on solid grounds

This second edition followed a workshop organised by Prof. Michel Gingras at the Perimeter Institute (Waterloo, Canada) in 2017. The 8 years since then have witnessed an exciting burst of activities in this vibrant field of research, both experimental and theoretical, with particular focus on cerium-based and praseodymium-based pyrochlore materials, which motivated the organisation of a workshop in 2025.

QSI workshop 2025 at the Herzberg near Aarau

Together with colleagues from the Okinawa Institute of Science and Technology (Nic Shannon) and the University of Waterloo (Michel Gingras), CNM scientists from the Laboratory for Neutron Scattering and Imaging (Romain Sibille, Tom Fennell and Michel Kenzelmann) have organized the second international workshop on quantum spin ice. The meeting was held during 14-17 October at the Herzberg, near Aarau.

An ambitious program over 3 full days

The workshop was highly successful and brought together experts in the field to discuss the accomplished progress and perspectives for future developments. The program intended to cover fundamental aspects of the emergent quantum electrodynamics, its predicted signatures, and the experimental realizations. 

The details of the contributions can be consulted from the event's website: https://indico.psi.ch/e/qsi2025

The 40 participants could enjoy a thorough review of the field throughout a total of 28 presentations, out of which 19 by invited speakers.

The event was especially recognized by the participants for having developed interdisciplinary communication and collaborations among internationally leading experts while having also promoted young researchers contributing to the field.

Funding

The workshop was sponsored by the Laboratory for Neutron Scattering & Imaging at PSI, the Swiss Academy of Sciences (SCNAT) and the Swiss National Science Foundation (grant number 219947 - Probing and controlling emergent electrodynamics in quantum spin ice materials).
