Aspects of nonrelativistic strings

G Oling, Z Yan - Frontiers in Physics, 2022 - frontiersin.org
We review recent developments on nonrelativistic string theory. In flat spacetime, the theory
is defined by a two-dimensional relativistic quantum field theory with nonrelativistic global …

Carrollian hydrodynamics from symmetries

L Freidel, P Jai-akson - Classical and Quantum Gravity, 2023 - iopscience.iop.org
In this work, we revisit Carrollian hydrodynamics, a type of non-Lorentzian hydrodynamics
which has recently gained increasing attentions due to its underlying connection with …

Strings with non-relativistic conformal symmetry and limits of the AdS/CFT correspondence

T Harmark, J Hartong, L Menculini, NA Obers… - Journal of High Energy …, 2018 - Springer
A bstract We find a Polyakov-type action for strings moving in a torsional Newton-Cartan
geometry. This is obtained by starting with the relativistic Polyakov action and fixing the …

Boosting to BMS

A Bagchi, A Banerjee, H Muraki - Journal of High Energy Physics, 2022 - Springer
A bstract Bondi-Metzner-Sachs (BMS) symmetries, or equivalently Conformal Carroll
symmetries, are intrinsically associated to null manifolds and in two dimensions can be …

Field theories with conformal Carrollian symmetry

A Bagchi, A Mehra, P Nandi - Journal of High Energy Physics, 2019 - Springer

(BMS) groups that arise as the asymptotic symmetries at the null boundary of Minkowski …

Carroll covariant scalar fields in two dimensions

A Bagchi, A Banerjee, S Dutta, KS Kolekar… - Journal of High Energy …, 2023 - Springer
A bstract Conformal Carroll symmetry generically arises on null manifolds and is important
for holography of asymptotically flat spacetimes, generic black hole horizons and …

More on quantum chiral higher spin gravity

E Skvortsov, T Tran, M Tsulaia - Physical Review D, 2020 - APS
Chiral higher spin gravity is unique in being the smallest higher spin extension of gravity and
in having a simple local action both in flat and (anti-) de Sitter spaces. It must be a closed …

Longitudinal Galilean and Carrollian limits of non-relativistic strings

L Bidussi, T Harmark, J Hartong, NA Obers… - Journal of High Energy …, 2023 - Springer
A bstract It is well known that one can take an infinite speed of light limit that gives rise to non-
relativistic strings with a relativistic worldsheet sigma model but with a non-relativistic target …

Map** relativistic to ultra/non-relativistic conformal symmetries in 2D and finite deformations
