Phys. Rev. A 65, 034707 (2002) [4 pages]Duality and quasiparticles in the Calogero-Sutherland model: Some exact resultsReceived 5 October 2000; published 26 February 2002 A quantum-mechanical many-body system with a potential proportional to the pairwise inverse-square distance possesses a strong-weak coupling duality. Using this duality we construct a parent Hamiltonian describing the system of particles and quasiparticles. The construction of the Hamiltonian and the solutions found are of a hierarchical nature. © 2002 The American Physical Society URL:
