Fernández Núñez, José García Fuertes, Wifredo Perelomov, Askold M. 2013-05-11T20:20:02Z 2013-05-11T20:20:02Z 2009 Fernandez Nuñez J., Garcia Fuertes W.,and Perelomov A.M. (2008). Quantum trigonometric Calogero-Sutherland model and irreducible characters for the exceptional algebra E8. J. Phys. A: Math. Theor. 42 http://hdl.handle.net/10366/121458 [EN] We express the Hamiltonian of the quantum trigonometric Calogero-Sutherland model for the Lie algebra E8 and coupling constant k=1 by using the fundamental irreducible characters of the algebra as dynamical independent variables. Then, we compute the second order characters of the algebra and some higher order characters.[ES] Expresamos el hamiltoniano del modelo trigonométrico Calogero-Sutherland cuántico para el álgebra de Lie E8 y el acoplamiento constante k = 1 mediante el uso de los caracteres irreducibles fundamentales del álgebra como variables independientes dinámicos. A continuación, se calcula el caracter de segundo orden del álgebra y algunos caracteres de orden superior. eng https://creativecommons.org/licenses/by-nc-nd/3.0/ info:eu-repo/semantics/openAccess Attribution-NonCommercial-NoDerivs 3.0 Unported Mathematical Physics Física matemática Exactly Solvable and Integrable Systems Sistemas exactamente resolubles y Integrable Lie Algebra Álgebra Quantum trigonometric Calogero-Sutherland model and irreducible characters for the exceptional algebra E8 info:eu-repo/semantics/article
