CANONICAL APPROACH TO 2D INDUCED GRAVITY [PDF]
Modern Physics Letters A, 2001 Using canonical method the Liouville theory has been obtained as a gravitational Wess–Zumino action of the Polyakov string. From this approach it is clear that the form of the Liouville action is the consequence of the bosonic representation of the Virasoro algebra, and that the coefficient in front of the action is proportional to the central charge ...

Gravitational perturbations as TT¯-deformations in 2D dilaton gravity systems [PDF]
, 2020 We consider gravitational perturbations of 2D dilaton gravity systems and show that these can be recast into -deformations (at least) under certain conditions, where T means the energy-momentum tensor of the matter field coupled to a dilaton gravity.

New perspective on matter coupling in 2D quantum gravity
, 1999 We provide compelling evidence that a previously introduced model of nonperturbative 2D Lorentzian quantum gravity exhibits (two-dimensional) flat-space behavior when coupled to Ising spins.

Scientific Reports, 2021 Due to the independence of the gradiometer instrument’s orientation in space, the second invariant $$I_2$$ I 2 of gravity gradients in combination with individual gravity gradients are demonstrated to be valid for gravity field determination.

Matrix integrals & finite holography
Journal of High Energy Physics, 2021 We explore the conjectured duality between a class of large N matrix integrals, known as multicritical matrix integrals (MMI), and the series (2m − 1, 2) of non-unitary minimal models on a fluctuating background.

Poisson-sigma model for 2D gravity with non-metricity
, 2007 We present a Poisson-sigma model describing general 2D dilaton gravity with non-metricity, torsion and curvature. It involves three arbitrary functions of the dilaton field, two of which are well known from metric compatible theories, while the third one

Grey-body factors, irreversibility and multiple island saddles
Journal of High Energy Physics, 2022 We consider the effect of grey-body factors on the entanglement island prescription for computing the entropy of an arbitrary subset of the Hawking radiation of an evaporating black hole.

Bulk Correlation Functions in 2d Quantum Gravity [PDF]
Theoretical and Mathematical Physics, 2006 We compute bulk 3- and 4-point tachyon correlators in the 2d Liouville gravity with non-rational matter central charge c<1, following and comparing two approaches. The continuous CFT approach exploits the action on the tachyons of the ground ring generators deformed by Liouville and matter ``screening charges''.
