A short, graduate-level synthesis of recent developments in theoretical physics, from a
pioneer in the field Lectures on the Infrared Structure of Gravity and Gauge Theory presents …

A bstract The conformal algebra in 2D (Diff (S 1)⨁ Diff (S 1)) is shown to be preserved under
a nonlinear map that mixes both chiral (holomorphic) generators T and\(\overline {T}\). It …

A bstract The conformal symmetry algebra in 2D (Diff (S 1)⊕ Diff (S 1)) is shown to be
related to its ultra/non-relativistic version (BMS 3≈ GCA 2) through a nonlinear map of the …

We discuss some aspects of soft hairy black holes and a new kind of “soft hairy
cosmologies,” including a detailed derivation of the metric formulation, results on flat space …

A bstract We investigate the supersymmetric versions of Bondi-Metzner-Sachs or,
equivalently, conformal Carroll symmetry in boundary dimensions d> 3, with applications of …

A bstract In this paper we perform the Hamiltonian reduction of the action for three-
dimensional Einstein gravity with vanishing cosmological constant using the Chern-Simons …

We provide the first explicit proposal for all microstates of generic black holes in three
dimensions (of Bañados-Teitelboim-Zanelli type): black hole microstates, termed “horizon …

A bstract We explicitly show how the field dependent 2-cocycle that arises in the current
algebra of 4 dimensional asymptotically flat spacetimes can be used as a central extension …

A bstract The asymptotically flat structure of\(\mathcal {N}=\left (2, 0\right)\) supergravity in
three spacetime dimensions is explored. The asymptotic symmetries are found to be …
