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 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 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 In this work, we investigate the time evolution of the pseudo-(Rényi) entropy after
local primary operator quenches in 2D CFTs with\(T\overline {T}/J\overline {T}\)-deformation …

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 …

We compute the partition function of 2D Jackiw-Teitelboim (JT) gravity at finite cutoff in two
ways:(i) via an exact evaluation of the Wheeler-DeWitt wavefunctional in radial quantization …

We study interacting theories of N left-moving and N¯ right-moving Floreanini-Jackiw
bosons in two dimensions. A parametrized family of such theories is shown to enjoy …

A bstract This letter explores a transition in the type of von Neumann algebra for
asymptotically AdS spacetimes from the implementations of the different gravitational …
