Polaron Crossover and Bipolaronic Metal-Insulator Transition in the Holstein model at half-filling
M. Capone, P. Carta, S. Ciuchi
The evolution of the properties of a finite density electronic system as the electron-phonon coupling is increased are investigated in the Holstein model using the Dynamical Mean-F…
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…
Functional Approach to Classical Yang-Mills Theories
P. Carta, D. Mauro
Sometime ago it was shown that the operatorial approach to classical mechanics, pioneered in the 30's by Koopman and von Neumann, can have a functional version. In this talk we wil…
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…
Open Strings, Holography and Stochastic Processes
Mariano Cadoni, Paolo Carta
We use the correspondence between string states and local operators on the world-sheet boundary defined by vertex operators in open string theory to put in correspondence, holograp…
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…
Third Order Renormalization Group applied to the attractive one-dimensional Fermi Gas
Paolo Carta
We consider a Callan-Symanzik and a Wilson Renormalization Group approach to the infrared problem for interacting fermions in one dimension with backscattering. We compute the thir…
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…
