Robustness of gauge-invariant dynamics against defects in ultracold-atom gauge theories
Robustness of gauge-invariant dynamics against defects in ultracold-atom gauge theories
Recent years have seen strong progress in quantum simulation of gauge-theory dynamics using ultracold-atom experiments. A principal challenge in these efforts is the certification of gauge invariance, which has recently been realized in [B.~Yang et al., arXiv:2003.08945]. One major but poorly investigated experimental source of gauge-invariance violation is an imperfect …
