Rationale and Scope:

In quantum materials, quantum fluctuations reduce the tendency towards conventional orders that fall within the classification of spontaneous symmetry breaking. They may instead drive more exotic orders that are beyond the Landau framework, such as quantum spin liquids and quantum Hall states. They can also give rise to the regime of quantum criticality and, in gapless settings, to strange metallicity. There is increasing recognition that such hidden-order systems are highly entangled and, important, recent development has allowed for the detection of quantum entanglement in such many-body settings. The interplay between highly-fluctuating quantum materials and quantum information has the potential to bring about new advancements in both fields.

This workshop, in part in celebration of UNESCO’s 2025 International Year of Quantum Science and Technology, will survey the recent progress and future prospects for research in this emerging cross-cutting field. It will bring together experts and early-career researchers from communities with varied perspectives and involving different platforms, which include:

• Entanglement witnesses
• Quantum spin liquids
• Strange metals
• Quantum Hall systems
• Quantum emulators.

The workshop, organized by Rice University’s Extreme Quantum Materials Alliance (eQMA) in collaboration with the Smalley-Curl Institute (SCI), will bring together a diverse pool of theoretical and experimental experts on these topics. Specific topics to be discussed during the workshop include:

• The extent to which quantum information tools can advance the understanding of quantum materials with exotic orders.
• The prospect of quantum materials in the highly-fluctuating regime to realize new capacities for quantum technologies.

The total number of invited speakers will be about 20.

The registration fee is $50 for Rice University attendees, and $200 for non-Rice attendees. The registration fee is waived for the invited speakers and eQMA/RCQM/SCI faculty.

The workshop expects to have a (limited) number of junior fellowships to support non-Rice early-career participants.
