New superintegrable models with position-dependent mass from Bertrand's Theorem on curved spaces
Angel Ballesteros, Alberto Enciso, Francisco J. Herranz +2
A generalized version of Bertrand's theorem on spherically symmetric curved spaces is presented. This result is based on the classification of (3+1)-dimensional (Lorentzian) Bertra…
On two superintegrable nonlinear oscillators in N dimensions
Angel Ballesteros, Alberto Enciso, Francisco J. Herranz +2
We consider the classical superintegrable Hamiltonian system given by , where U is known to be the "intrinsic" oscillator potential o…
On the level density of spin chains of Haldane--Shastry type
A. Enciso, F. Finkel, A. Gonzalez-Lopez
We provide a rigorous proof of the fact that the level density of all su(m) spin chains of Haldane-Shastry type associated with the A_{N-1} root system approaches a Gaussian distri…
Spinor Green's functions via spherical means on products of space forms
Alberto Enciso, Niky Kamran
We explicitly compute the Green's function of the spinor Klein-Gordon equation on the Riemannian and Lorentzian manifolds of the form , with each factor…
Knots and links in steady solutions of the Euler equation
Alberto Enciso, Daniel Peralta-Salas
Given any possibly unbounded, locally finite link, we show that there exists a smooth diffeomorphism transforming this link into a set of stream (or vortex) lines of a vector field…
Global causal propagator for the Klein-Gordon equation on a class of supersymmetric AdS backgrounds
Alberto Enciso, Niky Kamran
We analyze the Cauchy problem for the Klein-Gordon equation on the type IIB supergravity backgrounds , where is any of the Sasaki-Einstein 5-manifol…
