文摘In order to analyze a limiting case of the 1D delta anyon model,the coupling strength of the δ interactionc is modified to become a function of the anyonic parameter κ.A pedagogic derivation of the solution for this modifiedmodel using the method of anyon-boson mapping plus Bethe ansatz is presented.The limiting case as κ→π andsimultaneously c→0,which was previously neglected,is analyzed.Some unexpected properties of this limiting case arediscovered.The BAEs are compared with previous results.
