A strong‐weak coupling duality appears in the quantum mechanical many body system with the interacting potential proportional to the pair‐wise inverse‐squared distance. In the large N limit the field theory formulation possess the soliton solution in non‐perturbative “Bogomolny‐Prasad‐Sommerfeld” limit (BPS). In this limit we establish duality between original and soliton fields and the dual relation among coupling constants.
