Reconstruction through a coisotropic reduction: the missing momentum on a Poincaré section as a branched covering

E. Chan-López

Determining the momentum missing on a Poincaré section of a two-degree-of-freedom Hamiltonian is usually posed as the root-finding problem , which degenerates a…

Newton geometry of Bogdanov-Takens degeneracies in integrable dilatonic models: invariant divisors and boundary multiplicity

E. Chan-López, A. Martín-Ruiz, J. M. Paulin Fuentes

The Kantowski--Sachs interior of Grumiller's two-dimensional dilaton gravity model reduces to , , where is the expansion rate of the…

From Null Modes to Gauge Generators: A Bordered Faddeev--Jackiw Theory of Constraint Chains

E. Chan-López

A null mode of the bordered Faddeev--Jackiw matrix is not, in general, a gauge generator. We determine exactly what the residual kernel encodes and identify the additional conditio…

The Bogdanov--Takens normal-form coefficients in as directional derivatives of the characteristic invariants

E. Chan-López

Let be a vector field on an open set of with and Jacobian of rank having as an eigenvalue of algebraic multiplicity two. Let s…

Matrix bordering structure of the Faddeev-Jackiw algorithm: kernel reduction and symbolic automation

E. Chan-López, A. Martín-Ruiz, Jaime Manuel Cabrera +1

We show that the iterative Faddeev-Jackiw (FJ) reduction for singular Lagrangian systems constitutes a geometrically constrained instance of the Matrix Bordering Technique (MBT). S…

Casimir effect in polymer scalar field theory

C. A. Escobar, E. Chan-López, A. Martín-Ruiz

In this paper, we study the Casimir effect in the classical geometry of two parallel conducting plates, separated by a distance , due to the presence of a minimal length ari…

Dynamics of a Rydberg hydrogen atom near a topologically insulating surface

A. Martín-Ruiz, E. Chan-López

We investigate the classical dynamics of a Rydberg hydrogen atom near the surface of a planar topological insulator. The system is described by a Hamiltonian consisting of the free…

Tunneling of Polymer Particles

A. Martín-Ruiz, E. Chan-López, A. Carbajal-Domínguez +1

In this paper we study the tunneling using a background independent (polymer) quantization scheme. We show that at low energies, for the tunneling through a single potential barrie…
