Fractional Galilean Symmetries
Ali Hosseiny, Shahin Rouhani
We generalize the differential representation of the operators of the Galilean algebras to include fractional derivatives. As a result a whole new class of scale invariant Galilean…
Possible Central Extensions of Non-Relativistic Conformal Algebras in 1+1
Ali Hosseiny
We investigate possibility of central extension for non-relativistic conformal algebras in 1+1 dimension. Three different forms of charges can be suggested. A trivial charge for te…
Logarithmic Exotic Conformal Galilean Algebras
Malte Henkel, Ali Hosseiny, Shahin Rouhani
Logarithmic representations of the conformal Galilean algebra (CGA) and the Exotic Conformal Galilean algebra ({\sc ecga}) are constructed. This can be achieved by non-decomposable…
On Holographic Realization of Logarithmic GCA
Ali Hosseiny, Ali Naseh
We study 2-dimensional Logarithmic Galilean Conformal Algebra (LGCA) by making use of a contraction of Topologically Massive Gravity at critical point. We observe that using a naiv…
Logarithmic Correlators in Non-relativistic Conformal Field Theory
Ali Hosseiny, Shahin Rouhani
We show how logarithmic terms may arise in the correlators of fields which belong to the representation of the Schrodinger-Virasoro algebra (SV) or the affine Galilean Conformal Al…
Affine Extension of Galilean Conformal Algebra in 2+1 Dimensions
Ali Hosseiny, Shahin Rouhani
We show that a class of nonrelativistic algebras including non centrally-extended Schrodinger algebra and Galilean Conformal Algebra (GCA) has an affine extension in 2+1 hitherto u…
