Magnon decay below the critical field in the S=1/2 Heisenberg antiferromagnet...

In this continuation proposal, we propose to study the spin excitations of the spin 1/2 square lattice Heisenberg antiferromagnet CAPCC in fields just below its saturation...在本续项研究提案中，我们拟研究自旋1/2方格晶格海森堡反铁磁体（Heisenberg antiferromagnet）CAPCC在略低于其饱和场的磁场中的自旋激发（spin excitations）特性。
