Logarithmic CFT on the Boundary and the World-Sheet
Alex Lewis
The correspondences between logarithmic operators in the CFTs on the boundary of AdS_3 and on the world-sheet and dipole fields in the bulk are studied using the free field formula…
Logarithmic Operators in AdS_3/CFT_2
Alex Lewis
We discuss the relation between singletons in AdS_3 and logarithmic operators in the CFT on the boundary. In 2 dimensions there can be more logarithmic operators apart from those w…
Renormalization group flow and parallel transport with non-metric compatible connections
Brian P. Dolan, Alex Lewis
A family of connections on the space of couplings for a renormalizable field theory is defined. The connections are obtained from a Levi-Civita connection, for a metric which is a…
Vacuum Instability in Topologically Massive Gauge Theory
Alex Lewis
We find the critical charge for a topologically massive gauge theory for any gauge group, generalising our earlier result for SU(2). The relation between critical charges in TMGT,…
Vacuum Instability in Chern-Simons Theory, Null Vectors and Two-Dimensional Logarithmic Operators
Ian I. Kogan, Alex Lewis
A new relation between two-dimensional conformal field theories and three-dimensional topologically massive gauge theories is found, where the dynamical nature of the 3d theory is…
Origin of Logarithmic Operators in Conformal Field Theories
Ian I. Kogan, Alex Lewis
We study logarithmic operators in Coulomb gas models, and show that they occur when the ``puncture'' operator of the Liouville theory is included in the model. We also consider WZN…
