Using Polychronakos's freezing trick, we derive an exact formula for the partition function of its associated Haldane-Shastry spin chain.engjournal articlehttp://dx.doi.org/10.2991/jnmp.2005.12.s1.21http://www.tandfonline.comhttp://www.researchgate.net/publication/2061884_A_Haldane-Shastry_spin_chain_of_BC_N_type_in_a_constant_magnetic_field/file/79e415106a32fa4d22.pdopen access51-73Física-Modelos matemáticosFísica matemática
