The definition and structure of hyperkähler structure preserving transformations (invariance group) for quaternionic structures have been recently studied and some preliminary results on the Euclidean case discussed. In this work we present the [...]![]()

Barba, J. C. ; Finkel Morgenstern, Federico ; González López, Artemio ; Rodríguez González, Miguel Ángel | EPL Association, European Physical Society | 2008-07According to a long-standing conjecture of Berry and Tabor, the distribution of the spacings between consecutive levels of a "generic" integrable model should follow Poisson's law. In contrast, the spacings distribution of chaotic systems typica[...]![]()

Finkel Morgenstern, Federico ; González López, Artemio ; López Maroto, Antonio ; Rodríguez González, Miguel Ángel | American Physical Society | 2000-10-17We show that the most general inflaton potential in Minkowski spacetime for which the differential equation for the Fourier modes of the matter fields reduces to Lame's equation is of the form V(phi)=lambda phi^4/4+Kphi^2/2+mu/(2 phi^2)+V_0. As [...]![]()

Finkel Morgenstern, Federico ; González López, Artemio ; León Yebra, Carlos ; Rodríguez González, Miguel Ángel | IOP Publishing | 2018-04We study the thermodynamics and critical behavior of su(m|n) supersymmetric spin chains of Haldane-Shastry type with a chemical potential term. We obtain a closed-form expression for the partition function and deduce a description of the spectru[...]
