Quantum chromodynamics, antiferromagnets and XY models from a unified point of view
Antiferromagnets and quantum XY magnets in three space dimensions are described by an effective Lagrangian that exhibits the same structure as the effective Lagrangian of quantum chromodynamics with two light flavors. These systems all share a spontaneously broken internal symmetry O(N)→O(N−1). Alth...
