Talk by Prof. Alan Tennant on quantum magnetism

Prof. Alan Tennant

We are delighted to welcome Prof. Alan Tennant from the University of Tennessee in Knoxville, who will be giving a lecture on quantum magnetism.

More on the topic: Quantum magnetism has long provided the deepest experimental tests of quantum field theory in condensed matter. From the discovery of spin fractionalization and emergent gauge fields to the first observation of E₈ symmetry in a real material, neutron scattering has made visible many of the abstract structures once confined to theory.

Today, those same quantum magnetic systems are becoming benchmarks for quantum computation. Dimerized and frustrated magnets—whose excitations and correlations can be mapped with high precision—now serve as testbeds for validating quantum algorithms and hardware. The interplay between experiment, artificial intelligence, and quantum simulation is transforming quantum magnetism from a field of discovery into one of predictive design.

This talk will trace that evolution—from the verification of field theories in low-dimensional magnets to the emergence of quantum–AI–neutron co-design frameworks. It will also explore how non-perturbative effects, quantum criticality, and entanglement measures inform the new directions.
