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…
Aspects of Ultra-Relativistic Field Theories via Flat-space Holography
Reza Fareghbal, Ali Naseh, Shahin Rouhani
Recently it was proposed that asymptotically flat spacetimes have a holographic dual which is an ultra-relativistic conformal field theory. In this paper, we obtain the conformal a…
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…
Logarithmic correlators or responses in non-relativistic analogues of conformal invariance
Malte Henkel, Shahin Rouhani
Recent developments on emergence of logarithmic terms in correlators or response functions of models which exhibit dynamical symmetries analogous to conformal invariance in not nec…
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…
