The classical Darboux III oscillator: factorization, Spectrum Generating Algebra and solution to the equations of motion
Angel Ballesteros, Alberto Enciso, Francisco J. Herranz +3
In a recent paper the so-called Spectrum Generating Algebra (SGA) technique has been applied to the N-dimensional Taub-NUT system, a maximally superintegrable Hamiltonian system wh…
Haantjes Structures for the Jacobi-Calogero Model and the Benenti Systems
Giorgio Tondo, Piergiulio Tempesta
In the context of the theory of symplectic-Haantjes manifolds, we construct the Haantjes structures of generalized Stäckel systems and, as a particular case, of the quasi-bi-Hamilt…
Quantum Tomography twenty years later
M. Asorey, A. Ibort, G. Marmo +1
A sample of some relevant developments that have taken place during the last twenty years in classical and quantum tomography are displayed. We will present a general conceptual fr…
The Topology and Geometry of self-adjoint and elliptic boundary conditions for Dirac and Laplace operators
M. Asorey, A. Ibort, G. Marmo
The theory of self-adjoint extensions of first and second order elliptic differential operators on manifolds with boundary is studied via its most representative instances: Dirac a…
Towards a quantum sampling theory: the case of finite groups
Antonio G. García, Miguel A. Hernández-Medina, A. Ibort
Nyquist-Shannon sampling theorem, instrumental in classical telecommunication technologies, is extended to quantum systems supporting a unitary representation of a finite group …
The combinatorics of Green's functions in planar field theories
Kurusch Ebrahimi-Fard, Frederic Patras
The aim of this work is to outline in some detail the use of combinatorial algebra in planar quantum field theory. Particular emphasis is given to the relations between the differe…
Formal Groups and -Entropies
Piergiulio Tempesta
We shall prove that the celebrated Rényi entropy is the first example of a new family of infinitely many multi-parametric entropies. We shall call them the -entropies. Each of t…
Hamilton-Jacobi theory in multisymplectic classical field theories
Manuel de León, Pedro Daniel Prieto-Martínez, Narciso Román-Roy +1
The geometric framework for the Hamilton-Jacobi theory developed in previous works is extended for multisymplectic first-order classical field theories. The Hamilton-Jacobi problem…
Nilpotent integrability, reduction of dynamical systems and a third-order Calogero-Moser system
A. Ibort, G. Marmo, M. A. Rodriguez +1
We present an algebraic formulation of the notion of integrability of dynamical systems, based on a nilpotency property of its flow: it can be explicitly described as a polynomial…
