摘要:Confinement is a fundamental phenomenon in physics, with color confinement in quantum chromodynamics (QCD) being a prime example: quarks and gluons cannot be isolated individually but only appear in bound states such as mesons, hadrons, and glueballs. An analytic understanding of color confinement remains an open problem. However, confinement is not unique to QCD, it also emerges in low-dimensional quantum many-body systems, exhibiting interesting parallels with QCD. In this talk, I will first discuss confinement in Ising field theory, where elementary fermions become confined and form mesons. I will review both analytic and numerical methods for determining the meson spectrum of this theory. I will then turn to the Ising ladder theory, consisting of two coupled Ising chains, and examine its meson spectrum. Remarkably, the resulting Bethe–Salpeter equation shows close similarities to that of two-dimensional QCD.
