Eikonal, nonlocality and regular black holes
Mariano Cadoni, Lorenzo Herres, Leonardo Modesto +2
We investigate the leading gravitational eikonal in nonlocal dimensional theories of gravity. We analyze the simplest cases of massless and massive scalar scatt…
BPS-like bound and thermodynamics of the charged BTZ black hole
M. Cadoni, C. Monni
The charged Banados-Teitelboim-Zanelli (BTZ) black hole is plagued by several pathologies: a) Presence of divergent boundary terms in the action, hence of a divergent black hole ma…
Horizons and the Thermal Harmonic Oscillator
M. Cadoni
We show that two-dimensional anti-de Sitter spacetime (AdS_2) can be put in correspondence, holographically, both with the harmonic oscillator and the free particle. When AdS_2 has…
Tachyons in de Sitter space and analytical continuation from dS/CFT to AdS/CFT
M. Cadoni, P. Carta
We discuss analytic continuation from d-dimensional Lorentzian de Sitter (dS) to d-dimensional Lorentzian anti-de Sitter (AdS) spacetime. We show that AdS, with opp…
Two-dimensional dS/CFT correspondence
M. Cadoni, P. Carta, M. Cavaglia' +1
We investigate de Sitter/conformal field theory (dS/CFT) correspondence in two dimensions. We define the conserved mass of de Sitter spacetime and formulate the correspondence alon…
Quantum dilaton gravity as a linear dilaton conformal field theory
M. Cadoni, P. Carta, S. Mignemi
A model of matter-coupled gravity in two dimensions is quantized. The crucial requirement for performing the quantization is the vanishing of the conformal anomaly, which is achiev…
The Cardy-Verlinde formula for 2D gravity
M. Cadoni, P. Carta, S. Mignemi
We discuss the different bounds on entropy in the context of two-dimensional cosmology. We show that in order to obtain well definite bounds one has to use the scale symmetry of th…
Cosmology of the Jackiw-Teitelboim model
M. Cadoni, S. Mignemi
We investigate the cosmology of the two-dimensional Jackiw-Teitelboim model. Since the matter coupling is not defined uniquely, we consider two possible choices. The dilaton field…
Conformal Dynamics of 0-Branes
M. Cadoni, P. Carta, M. Cavaglia' +1
We investigate the dynamics of dilatonic D-dimensional 0-branes in the near-horizon regime. The theory is given in a twofold form: two-dimensional dilaton gravity and nonlinear sig…
The AdS/CFT correspondence in two dimensions
M. Cadoni, P. Carta
We review recent progress in understanding the anti-de Sitter/conformal field theory correspondence in the context of two-dimensional dilaton gravity theory.
Large N limit of Calogero-Moser models and Conformal Field Theories
M. Cadoni, P. Carta, D. Klemm
We discuss the large N limit of Calogero-Moser models for the classical infinite families of simple Lie algebras A_N, B_N, C_N and D_N. We show that the limit defines two different…
Hamiltonians for a general dilaton gravity theory on a spacetime with a non-orthogonal, timelike or spacelike outer boundary
M. Cadoni, P. G. L. Mana
A generalization of two recently proposed general relativity Hamiltonians, to the case of a general (d+1)-dimensional dilaton gravity theory in a manifold with a timelike or spacel…
AdS_2 Gravity as Conformally Invariant Mechanical System
M. Cadoni, P. Carta, D. Klemm +1
We show that two-dimensional (2D) AdS gravity induces on the spacetime boundary a conformally invariant dynamics that can be described in terms of a de Alfaro-Fubini-Furlan model c…
A Realization of the infinite dimensional Symmetries of Conformal Mechanics
M. Cadoni, P. Carta, S. Mignemi
We discuss the possibility of realizing the infinite dimensional symmetries of conformal mechanics as time reparametrizations, generalizing the realization of the SL(2,R) symmetry…
2D Extremal Black Holes as Solitons
M. Cadoni
We discuss the relationship between two-dimensional (2D) dilaton gravity models and sine-Gordon-like field theories. We show that there is a one-to-one correspondence between the s…
Dualities Compositeness and Spacetime Structure of 4d Extreme Stringy Black Holes
M. Cadoni
We study the BPS black hole solutions of the (truncated) action for heterotic string theory compactified on a six-torus. The O(3,Z) duality symmetry of the theory, together with th…
