Deconfined Quantum Critical Point in a Dissipative Spin-1/2 Chain
feeds.aps.org · By Longye Lu, Shifeng Cui & Wenan Guo ·
The Brief
- Lu, Cui and Guo study a spin-1/2 J−Q3 chain in an open quantum spin system.
- The chain combines an antiferromagnetic Heisenberg exchange with a competing multispin interaction.
- The authors argue that open quantum spin systems offer a previously unexplored route to realizing deconfined quantum criticality.
Why it matters
It proposes dissipation as a possible route to deconfined quantum criticality, extending a condensed-matter topic that is usually studied in closed systems.

Author(s): Longye Lu, Shifeng Cui, and Wenan Guo Open quantum spin systems offer a previously unexplored route to realizing deconfined quantum criticality. We consider a spin- 1 / 2 J − Q 3 chain composed of an antiferromagnetic (AFM) Heisenberg exchange and a competing multispin…
