Parity Order Drives Bosonic Topology
Analysis
This paper introduces a novel mechanism for realizing topological phases in interacting bosonic systems. It moves beyond fine-tuned interactions and enlarged symmetries, proposing that parity order, coupled with bond dimerization, can drive bosonic topology. The findings are significant because they offer a new perspective on how to engineer and understand topological phases, potentially simplifying their realization.

“The paper identifies two distinct topological phases: an SPT phase at half filling stabilized by positive parity coupling, and a topological phase at unit filling stabilized by negative coupling.”
