Non-Gaussian features of chaotic Hamiltonian transport

Roberto Venegeroles, Alberto Saa

Some non-Gaussian aspects of chaotic transport are investigated for a general class of two-dimensional area-preserving maps. Kurtosis, in particular, is calculated from the diffusi…

Lie Algebroids and Classification Problems in Geometry

Rui Loja Fernandes, Ivan Struchiner

We show how one can associate to a given class of finite type G-structures a classifying Lie algebroid. The corresponding Lie groupoid gives models for the different geometries tha…

Scaling of entanglement support for Matrix Product States

L. Tagliacozzo, Thiago. R. de Oliveira, S. Iblisdir +1

The power of matrix product states to describe infinite-size translational-invariant critical spin chains is investigated. At criticality, the accuracy with which they describe gro…

Obtaining the Gauge Invariant Kinetic Term for a SU(n) x SU(m) Lagrangian

Alex E. Bernardini

We propose a generalized way to formally obtain the gauge invariance of the kinetic part of a field Lagrangian over which a gauge transformation ruled by an $SU(n)_{U} \otimes SU(m…

From Dirac spinor fields to ELKO

Roldao da Rocha, Julio M. Hoff da Silva

Dual-helicity eigenspinors of the charge conjugation operator (ELKO spinor fields) belong, together with Majorana spinor fields, to a wider class of spinor fields, the so-called fl…

On Moduli Spaces for Abelian Categories

Vyacheslav Futorny, Marcos Jardim, Adriano Moura

We show that if A is an abelian category satisfying certain mild conditions, then one can introduce the concept of a moduli space of (semi)stable objects which has the structure of…
