de Sitter Microstates from and the Hawking-Page Transition
Evan Coleman, Edward A. Mazenc, Vasudev Shyam +4
We obtain microstates accounting for the Gibbons-Hawking entropy in , along with a subleading logarithmic correction, from the solvable deformation of a seed CF…
Hyperbolic compactification of M-theory and de Sitter quantum gravity
G. Bruno De Luca, Eva Silverstein, Gonzalo Torroba
We present a mechanism for accelerated expansion of the universe in the generic case of negative-curvature compactifications of M-theory, with minimal ingredients. M-theory on a hy…
Mutual information superadditivity and unitarity bounds
Horacio Casini, Eduardo Testé, Gonzalo Torroba
We derive the property of strong superadditivity of mutual information arising from the Markov property of the vacuum state in a conformal field theory and strong subadditivity of…
Aspects of quantum information in finite density field theory
Lucas Daguerre, Raimel Medina, Mario Solis +1
We study different aspects of quantum field theory at finite density using methods from quantum information theory. For simplicity we focus on massive Dirac fermions with nonzero c…
Irreversibility in quantum field theories with boundaries
Horacio Casini, Ignacio Salazar Landea, Gonzalo Torroba
We study conformal field theories with boundaries, and their boundary renormalization group (RG) flows, using methods from quantum information theory. Positivity of the relative en…
Renyi relative entropies and renormalization group flows
Horacio Casini, Raimel Medina, Ignacio Salazar +1
Quantum Renyi relative entropies provide a one-parameter family of distances between density matrices, which generalizes the relative entropy and the fidelity. We study these measu…
De Sitter Holography and Entanglement Entropy
Xi Dong, Eva Silverstein, Gonzalo Torroba
We propose a new example of entanglement knitting spacetime together, satisfying a series of checks of the corresponding von Neumann and Renyi entropies. The conjectured dual of de…
All the entropies on the light-cone
Horacio Casini, Eduardo Teste, Gonzalo Torroba
We determine the explicit universal form of the entanglement and Renyi entropies, for regions with arbitrary boundary on a null plane or the light-cone. All the entropies are shown…
Varying dilaton as a tracer of classical string interactions
Matthew Dodelson, Eva Silverstein, Gonzalo Torroba
We analyze tree-level string amplitudes in a linear dilaton background, motivated by its use as a gauge-invariant tracer of string interactions in scattering experiments and its ge…
Markov property of the CFT vacuum and the a-theorem
Horacio Casini, Eduardo Teste, Gonzalo Torroba
We use strong sub-additivity of entanglement entropy, Lorentz invariance, and the Markov property of the vacuum state of a conformal field theory to give a new proof of the irrever…
Modular Hamiltonians on the null plane and the Markov property of the vacuum state
Horacio Casini, Eduardo Teste, Gonzalo Torroba
We compute the modular Hamiltonians of regions having the future horizon lying on a null plane. For a CFT this is equivalent to regions with boundary of arbitrary shape lying on th…
Relative entropy and the RG flow
Horacio Casini, Eduardo Teste, Gonzalo Torroba
We consider the relative entropy between vacuum states of two different theories: a conformal field theory (CFT), and the CFT perturbed by a relevant operator. By restricting both…
Nonsupersymmetric dualities from mirror symmetry
Shamit Kachru, Michael Mulligan, Gonzalo Torroba +1
We study supersymmetry breaking perturbations of the simplest dual pair of 2+1-dimensional N = 2 supersymmetric field theories -- the free chiral multiplet and N = 2 super-QED with…
Bosonization and Mirror Symmetry
Shamit Kachru, Michael Mulligan, Gonzalo Torroba +1
We study bosonization in 2+1 dimensions using mirror symmetry, a duality that relates pairs of supersymmetric theories. Upon breaking supersymmetry in a controlled way, we dynamica…

Horacio Casini, Ignacio Salazar Landea, Gonzalo Torroba
We study boundary renormalization group flows between boundary conformal field theories in dimensions using methods of quantum information theory. We define an entropic -f…
Holographic RG flows, entanglement entropy and the sum rule
Horacio Casini, Eduardo Teste, Gonzalo Torroba
We calculate the two-point function of the trace of the stress tensor in holographic renormalization group flows between pairs of conformal field theories. We show that the term pr…
Exploring eternal stability with the simple harmonic universe
Peter W. Graham, Bart Horn, Surjeet Rajendran +1
We construct nonsingular cyclic cosmologies that respect the null energy condition, have a large hierarchy between the minimum and maximum size of the universe, and are stable unde…
Emergent Fermi surfaces, fractionalization and duality in supersymmetric QED
Anson Hook, Shamit Kachru, Gonzalo Torroba +1
We study the physics of 3d supersymmetric abelian gauge theories (with small supersymmetry breaking perturbations) at finite density. Using mirror symmetry, which provides a natura…

We study supersymmetric field theories in three space-time dimensions doped by various configurations of electric charges or magnetic fluxes. These are supersymmetric avatars of im…
Topological resolution of gauge theory singularities
Fabio Saracco, Alessandro Tomasiello, Gonzalo Torroba
Some gauge theories with Coulomb branches exhibit singularities in perturbation theory, which are usually resolved by nonperturbative physics. In string theory this corresponds to…
Black branes in flux compactifications
Gonzalo Torroba, Huajia Wang
We construct charged black branes in type IIA flux compactifications that are dual to (2+1)-dimensional field theories at finite density. The internal space is a general Calabi-Yau…
