Kink Collisions in Curved Field Space

Pontus Ahlqvist, Kate Eckerle, Brian Greene

We study bubble universe collisions in the ultrarelativistic limit with the new feature of allowing for nontrivial curvature in field space. We establish a simple geometrical inter…

Holographic Representation of Higher Spin Gauge Fields

Debajyoti Sarkar, Xiao Xiao

Extending the results of \cite{Heem}, \cite{KLRS} on the holographic representation of local gauge field operators in anti de Sitter space, here we construct the bulk operators for…

A non-linear extension of the spin-2 partially massless symmetry

Sebastian Garcia-Saenz, Rachel A. Rosen

We investigate the possibility of extending the "partially massless" symmetry of a spin-2 field in de Sitter to nonlinear order. To do so, we impose a closure condition on the symm…

Holographic Entanglement Entropy from 2d CFT: Heavy States and Local Quenches

Curtis T. Asplund, Alice Bernamonti, Federico Galli +1

We consider the entanglement entropy in 2d conformal field theory in a class of excited states produced by the insertion of a heavy local operator. These include both high-energy e…

Negative modes of Coleman-De Luccia bounces

Hakjoon Lee, Erick J. Weinberg

We investigate the negative modes about Coleman-De Luccia bounces governing vacuum transitions in de Sitter space, with the goal of gaining physical insight into the various anomal…

General coordinate invariance in quantum many-body systems

Tomas Brauner, Solomon Endlich, Alexander Monin +1

We extend the notion of general coordinate invariance to many-body, not necessarily relativistic, systems. As an application, we investigate nonrelativistic general covariance in G…

Holographic p-wave Superconductor with Disorder

Daniel Arean, Arya Farahi, Leopoldo A. Pando Zayas +2

We implement the effects of disorder on a holographic p-wave superconductor by introducing a random chemical potential which defines the local energy of the charge carriers. Since…

(Re-)Inventing the Relativistic Wheel: Gravity, Cosets, and Spinning Objects

Luca V. Delacretaz, Solomon Endlich, Alexander Monin +2

Space-time symmetries are a crucial ingredient of any theoretical model in physics. Unlike internal symmetries, which may or may not be gauged and/or spontaneously broken, space-ti…

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…

Wess-Zumino Terms for Relativistic Fluids, Superfluids, Solids, and Supersolids

Luca V. Delacrétaz, Alberto Nicolis, Riccardo Penco +1

We use the coset construction of low-energy effective actions to systematically derive Wess-Zumino (WZ) terms for fluid and isotropic solid systems in two, three and four spacetime…

Two-dimensional Lorentz invariance of spherically symmetric black holes

Lam Hui, Alberto Nicolis

We show that a static spherically symmetric black hole, in a generic theory of gravity with generic matter fields, has a two-dimensional Lorentz symmetry.

Holographic Representation of Local Operators In De Sitter Space

Xiao Xiao

Assuming the existence of the dS/CFT correspondence, we construct local scalar fields with in de Sitter space by smearing over conformal field th…

The Noether-Lefschetz Problem and Gauge-Group-Resolved Landscapes: F-Theory on K3 x K3 as a Test Case

Andreas P. Braun, Yusuke Kimura, Taizan Watari

Four-form flux in F-theory compactifications not only stabilizes moduli, but gives rise to ensembles of string vacua, providing a scientific basis for a stringy notion of naturalne…
