We review results concerning the critical behavior of spin systems at equilibrium. We
consider the Ising and the general O (N)-symmetric universality classes, including the N→ 0 …

The authors review the theory and phenomenology of instantons in quantum
chromodynamics (QCD). After a general overview, they provide a pedagogical introduction …

Studies of the structure of excited baryons are key factors to the N* program at Jefferson Lab
(JLab). Within the first year of data taking with the Hall B CLAS12 detector following the 12 …

We have simulated, using parallel tempering, the three-dimensional Ising spin glass model
with binary couplings in a helicoidal geometry. The largest lattice (L= 20) has been studied …

We provide strong evidence that the asymptotically free (1+ 1)-dimensional nonlinear O (3)
sigma model can be regularized using a quantum lattice Hamiltonian, referred to as the …

We present thermodynamic measurements of various physical observables of the two-
dimensional S= 1/2 isotropic quantum Heisenberg antiferromagnet on a square lattice …

Conventional lattice formulations of θ vacua in the 1+ 1-dimensional O (3) nonlinear sigma
model suffer from a sign problem. Here, we construct the first sign-problem-free …

The (1+ 1)-dimensional (1+ 1 D) O (3) nonlinear σ-model is a model system for future
quantum lattice simulations of other asymptotically free theories, such as non-Abelian gauge …

Quantum simulations of bosonic field theories require a truncation in field space to map the
theory onto finite quantum registers. Ideally, the truncated theory preserves the symmetries …
