"A New Era of Science at Jefferson Lab"

The continuous electron beam accelerator facility at Jefferson Lab, built with advanced superconducting radiofrequency (SRF) technology, provides opportunities to discover fundamental new aspects of the structure of visible matter – protons, neutrons and other states, and of the strong interaction, described by the gauge theory Quantum Chromodynamics.

"On Ising's model of ferromagnetism"

"On Ising's model of ferromagnetism"

The 1D Ising model is a classical model of great historical significance for both classical and quantum statistical mechanics. Developments in the understanding of the Ising model have fundamentally impacted our knowledge of thermodynamics, critical phenomena, magnetism, conformal quantum field theories, particle physics, and emergence in many-body systems.
