The Duality Symmetric String at Two-loops
Neil B. Copland, Giacomo Piccinini, Daniel C. Thompson
The Tseytlin duality symmetric string makes manifest the T-duality symmetry on the worldsheet at the expense of manifest Lorentz invariance. Here we consider the two-loop…
Holographic thermalization of mutual and tripartite information in 2d CFTs
Alice Bernamonti, Neil Copland, Ben Craps +1
We discuss the concepts of mutual and tripartite information by referring to simple intuitive examples, and describe their use as probes of thermalization in holographic models. We…
Superconformal Yang-Mills quantum mechanics and Calogero model with OSp(N|2,R) symmetry
Neil B. Copland, Sung Moon Ko, Jeong-Hyuck Park
In spacetime dimension two, pure Yang-Mills possesses no physical degrees of freedom, and consequently it admits a supersymmetric extension to couple to an arbitrary number, N say,…
Thermalization of mutual and tripartite information in strongly coupled two dimensional conformal field theories
V. Balasubramanian, A. Bernamonti, N. Copland +2
The mutual and tripartite information between pairs and triples of disjoint regions in a quantum field theory are sensitive probes of the spread of correlations in an equilibrating…
A Double Sigma Model for Double Field Theory
Neil B. Copland
We define a sigma model with doubled target space and calculate its background field equations. These coincide with generalised metric equation of motion of double field theory, th…
Connecting T-duality invariant theories
Neil B. Copland
We show that the vanishing of the one-loop beta-functional of the doubled formalism (which describes string theory on a torus fibration in which the fibres are doubled) is the same…
