BICEP/Keck and cosmological attractors

چکیده
Abstract We discuss implications of the latest BICEP/Keck data release for inflationary models, with special emphasis on cosmological attractors which can describe all presently available inflation-related observational data. These models are compatible any value tensor to scalar ratio r , way down = 0. Some string theory motivated this class predict 10 -3 ? -2 . The upper part range be explored by ongoing observations.

Non-supersymmetric Attractors in Born-Infeld Black Holes with a Cosmological Constant
We investigate the attractor mechanism for spherically symmetric extremal black holes in Einstein-Born-Infeld-dilaton theory of gravity in four-dimensions, in the presence of a cosmological constant. We look for solutions analytic near the horizon by using perturbation method. It is shown that the values of the scalar fields at the horizon are only dependent on the charges carried by the black ...
متن کاملAttractors and neo-attractors for 3D stochastic Navier-Stokes equations
In [14] nonstandard analysis was used to construct a (standard) global attractor for the 3D stochastic Navier–Stokes equations with general multiplicative noise, living on a Loeb space, using Sell’s approach [26]. The attractor had somewhat ad hoc attracting and compactness properties. We strengthen this result by showing that the attractor has stronger properties making it a neo-attractor – a ...
متن کاملBifurcations and Strange Attractors
We reviews the theory of strange attractors and their bifurcations. All known strange attractors may be subdivided into the following three groups: hyperbolic, pseudo-hyperbolic ones and quasi-attractors. For the first ones the description of bifurcations that lead to the appearance of Smale-Williams solenoids and Anosov-type attractors is given. The definition and the description of the attrac...
متن کاملSupersymmetry and attractors.
We find a general principle which allows one to compute the area of the horizon of N=2 extremal black holes as an extremum of the central charge. One considers the ADM mass equal to the central charge as a function of electric and magnetic charges and moduli and extremizes this function in the moduli space (a minimum corresponds to a fixed point of attraction). The extremal value of the square ...
متن کاملAttractors and Arithmetic
We consider attractor varieties arising in the construction of dyonic black holes in CalabiYau compactifications of IIB string theory. We show that the attractor varieties are constructed from products of elliptic curves with complex multiplication for N = 4, 8 compactifications. The heterotic dual theories are related to rational conformal field theories. The emergence of curves with complex m...
