Universal sectors of two-dimensional Carrollian CFTs

Ankit Aggarwal, Arjun Bagchi, Stephane Detournay +3

We revisit modular invariance in two-dimensional Carrollian conformal field theories from a geometric perspective. Focusing on the characters of the induced and highest-weight repr…

Carrollian c-functions and flat space holographic RG flows in BMS3/CCFT2

Daniel Grumiller, Max Riegler

We discuss c-functions and their holographic counterpart for two-dimensional field theories with Carrollian conformal fixed points in the UV and the IR. Specifically, we construct…

BMS modular covariance and structure constants

Arjun Bagchi, Saikat Mondal, Sanchari Pal +1

Two-dimensional (2d) field theories invariant under the Bondi-Metzner-Sachs algebra, or 2d BMSFTs in short, are putative holographic duals of Einstein gravity in 3d asymptotically…

BMS Field Theories with Symmetry

Arjun Bagchi, Ritankar Chatterjee, Rishabh Kaushik +3

We investigate quantum field theories in two dimensions (2d) with an underlying Bondi-van der Burgh-Metzner-Sachs (BMS) symmetry augmented by currents. These fiel…

Non-Lorentzian Chaos and Cosmological Holography

Arjun Bagchi, Shankhadeep Chakrabortty, Daniel Grumiller +3

We study chaos in non-Lorentzian field theories, specifically Galilean and Carrollian conformal field theories in two dimensions. In a large central charge limit, we find that the…

Scalar Fields in 3D Asymptotically Flat Higher-Spin Gravity

Martin Ammon, Michel Pannier, Max Riegler

In this work we construct a novel associative algebra and use it to define a theory of higher-spin gravity in (2+1)-dimensional asymptotically flat spacetimes. Our construction is…
