Open AccessTarget space entanglement in Matrix Models
We study target space entanglement in gauged multi-matrix models as models of entanglement between groups of D-branes separated by a planar entangling surface, paying close attention to the implementation of g...

Open AccessDivergences in open quantum systems
We show that for cubic scalar field theories in five and more spacetime dimensions, and for the T = 0 limit of the Caldeira-Leggett model, the quantum master equation for long-wavelength modes initially unentangl...

Open AccessEntanglement shadows in LLM geometries
We find a new example of an asymptotically AdS5 × S5 geometry which has an entanglement shadow: that is, a region of spacetime which no Ryu-Takayanagi minimal surface enters. Our example is a particular case of t...

Open AccessCausality & holographic entanglement entropy
We identify conditions for the entanglement entropy as a function of spatial region to be compatible with causality in an arbitrary relativistic quantum field theory. We then prove that the covariant holograph...

Open AccessMetastability and instability in holographic gauge theories
We review and extend previous results regarding the stability and thermodynamics of Anti-de Sitter (AdS) spacetime at finite temperature. Using a combination of analytic and numerical techniques, we compute th...

Open AccessHolographic interpretations of the renormalization group
In semiclassical holographic duality, the running couplings of a field theory are conventionally identified with the classical solutions of field equations in the dual gravitational theory. However, this ident...

Axion monodromy in a model of holographic gluodynamics
The low energy field theory for N type IIA D4-branes at strong ’t Hooft coupling, wrapped on a circle with antiperiodic boundary conditions for fermions, is known to have a vacuum energy which depends on the θ an...
