Strings near black holes are Carrollian. Part II Open
A bstract We study classical closed bosonic strings probing the near-horizon region of a non-extremal black hole and show that this corresponds to understanding string theory in the Carroll regime. This is done by first performing a Carrol…

Strings near black holes are Carrollian Open
We demonstrate that strings near the horizon of a Schwarzschild black hole, when viewed by a stationary observer at infinity, probe a string Carroll geometry, where the effective light speed is given by the distance from the horizon. We ex…

Non-relativistic expansion of open strings and D-branes Open
A bstract We expand the relativistic open bosonic string in powers of 1 /c 2 where c is the speed of light. We perform this expansion to next-to-leading order in 1 /c 2 and relate our results to known descriptions of non-relativistic open …

Massive carrollian fields at timelike infinity Open
A bstract Motivated by flat space holography, we demonstrate that massive spin- s fields in Minkowski space near timelike infinity are massive carrollian fields on the carrollian counterpart of anti-de Sitter space called Ti. Its isometrie…

Carrollian Fluids and Spontaneous Breaking of Boost Symmetry Open
In the hydrodynamic regime, field theories typically have their boost symmetry spontaneously broken due to the presence of a thermal rest frame although the associated Goldstone field does not acquire independent dynamics. We show that thi…

A coupling prescription for post-Newtonian corrections in quantum mechanics Open
The interplay between quantum theory and general relativity remains one of the main challenges of modern physics. A renewed interest in the low-energy limit is driven by the prospect of new experiments that could probe this interface. Here…

Motivated by flat space holography, we demonstrate that massive spin-$s$ fields in Minkowski space near timelike infinity are massive carrollian fields on the carrollian counterpart of anti-de Sitter space called $\mathsf{Ti}$. Its isometr…

We investigate the thermodynamics of equilibrium thermal states and their near-equilibrium dynamics in systems with fractonic symmetries in arbitrary curved space. By explicitly gauging the fracton algebra we obtain the geometry and gauge …

We develop a novel approach to non-relativistic closed bosonic string theory that is based on a string $1/c^2$ expansion of the relativistic string, where $c$ is the speed of light. This approach has the benefit that one does not need to t…
