Effective Field Theory of Chiral Spin Liquid between Ordered Phases in Kagom\'e Antiferromagnet

We propose in this work an effective field theory description of the chiral spin liquid state in Heisenberg spin system on kagome this http URL this end, we derive the low-energy effective theory of kagome (isotropic) Heisenberg antiferromagnet around its ordered ground states found numerically and show that quantum fluctuations induced by further neighbor spin exchanges are equally strong as those from first neighbor.We use a chiral order...
