论文摘要
我们考虑使用$ n $ fields的分布族理论。这些理论具有异国情调的时空对称性,包括保守的偶极矩。使用集体字段,我们解决了这些模型以大$ n $领先订单。大型$ n $解决方案表明,这些模型密切相关,并且相互作用产生了动量依赖的自我能源。在这些模型的整个相图中,偶极子对称性被自发断裂,从而导致对我们配音的“偶极子超流体”的低能戈德石描述。
We consider theories of fractons with $N$ fields. These theories have exotic spacetime symmetries, including a conserved dipole moment. Using collective fields we solve these models to leading order in large $N$. The large $N$ solution reveals that these models are strongly correlated, and that interactions generate a momentum-dependent self-energy. Dipole symmetry is spontaneously broken throughout the phase diagram of these models, leading to a low-energy Goldstone description of what we dub "dipole superfluids."
