Coleman's puzzles are solved: at θ=π with equal masses the model shows spontaneous charge conjugation breaking and no confinement with mass gap ~m exp(-0.111 g²/m²) at strong coupling; at θ=0 a level crossing occurs between isosinglet states; isospin-breaking effects are quantified for unequal mass.

A matrix product operator construction using link-enhanced MPOs enables infinite-lattice simulations of (1+1)D gauge theories with manifest translation invariance and symmetry.
Four PT-symmetric 1+1D quantum models are mapped to the Yang-Lee critical point via state-operator correspondence and bosonization, with scaling dimensions matching exact 2D results and a numerically confirmed growing two-point function.
In expanding de Sitter QED₂, a moving pseudo-critical line drives loss of adiabaticity, a late-time dip near τ_*≈3.1, and an LOCC-detectable irreversibility front in relative entropy.
Backreaction in semiclassical scalar QED in 1+1D avoids instabilities and produces over-screening at high external charges.
Abelian 2d gauge theories show rich phase structure with c=1 and c=1/2 critical lines; chiral versions realize symmetric mass generation for fermions.
