Comments on the Origin and Evolution of the Quantum Fluids and Solids Symposia

Abstract

The quantum fluids and solids symposium series had its origin as a symposium in a series of symposia related to the Quantum Theory Project—a joint program between the University of Florida and Uppsala University that started in 1960. In the present manuscript, we comment on the evolution of the QFS symposium series with a focus on the early years and emphasize the sense of community that has developed over the years. The quantum fluids and solids symposium series started with a nearly total focus on ³He, particularly superfluid ³He, and then expanded to more broadly cover primarily liquid and solid aspects of ³He, ⁴He and their mixtures but also related technical developments. More recently, the various symposia have broadened further to include aspects of other fields for which research in ³He and ⁴He has provided significant input due to fundamental investigations and technical innovation. In turn, some of these fields have returned the favor and provided stimulation to the quantum fluids and solids community.
