We review recent developments in Jackiw–Teitelboim gravity. This is a simple solvable
model of quantum gravity in two dimensions (that arises eg from the s-wave sector of higher …

This is a pedagogical review on TT deformation of two dimensional quantum field theories. It
is based on three lectures which the author gave at ITP-CAS in December 2018. This review …

A bstract We obtain microstates accounting for the Gibbons-Hawking entropy in dS 3, along
with a subleading logarithmic correction, from the solvable T\(\overline {T}\)+ Λ 2 deformation …

We develop a generic geometric formalism that incorporates both TT¯-like and root-TT¯-like
deformations in arbitrary dimensions. This framework applies to a wide family of stress …

A bstract The construction of exactly-solvable models has recently been advanced by
considering integrable\(T\overline {T}\) deformations and related Hamiltonian deformations …

A bstract In this paper we argue for a close connection between the non-existence of global
symmetries in quantum gravity and a unitary resolution of the black hole information …

A bstract We consider a one-parameter family of composite fields—bi-linear in the
components of the stress-energy tensor—which generalise the\(\mathrm {T}\overline …

A bstract In this work, we investigate the quantum chaos in various\(T\overline {T}\)-deformed
SYK models with finite N, including the SYK 4, the supersymmetric SYK 4, and the SYK 2 …

The complex Fourier transform of the two-point correlator of the energy spectrum of a
quantum system is known as the spectral form factor (SFF). It constitutes an essential …

A bstract We construct various limits of JT gravity, including Newton-Cartan and Carrollian
versions of dilaton gravity in two dimensions as well as a theory on the three-dimensional …
