“…The black hole solutions found possess hair [6] outside the horizon as anticipated from general and perturbative in α ′ considerations [7] [8]. The existence of black holes with non-trivial hair has been demonstrated in the Einstein-Maxwell-Dilaton system [9] [10] and the Einstein-Yang Mills(-Dilaton-Axion) system [11]. In the present article we shall extend the analysis of reference [4] by including an SU(2) Yang Mills field.…”

We consider the combined Yang Mills-Dilaton-Gravity system in the presence of a Gauss-Bonnet term as it appears in the 4D Effective Superstring Action. We give analytical arguments and demonstrate numerically the existence of black hole solutions with non-trivial dilaton and Yang Mills hair for the particular case of SU(2) gauge fields. The thermodynamical properties of the solutions are also discussed.

“…At the tree level, the electric and magnetic solutions are related by the transformation φ → −φ (Figure 2, b = 0 case) what makes it possible to concentrate only on the pure electric or pure magnetic 'dilatonic' solutions. Tree-level dyonic solutions with non-trivial axion of the complex dilaton field S can be found by the SL(2, R) Sduality transformations as in [34] [35]. Since the dilatonic S-duality is, however, broken by both perturbative and non-perturbative string corrections discused in this paper, one can no longer relate the electric and magnetic 'dilatonic' solutions (see Figure 2, b = 0 case).…”

We find charged, abelian, spherically symmetric solutions (in flat space-time) corresponding to the effective action of D = 4 heterotic string theory with the scale dependent dilaton φ and modulus ϕ fields. We take into account perturbative (genus-one), moduli-dependent 'threshold' corrections to the coupling function f (φ, ϕ) in the gauge field kinetic term f (φ, ϕ)F 2 µν , as well as non-perturbative scalar potential V (φ, ϕ), e.g., induced by gaugino condensation in the hidden gauge sector. Stable, finite energy, electric solutions (corresponding to on abelian subgroup of a non-abelian gauge group) have the small scale region as the weak coupling region (φ → −∞) with the modulus ϕ slowly varying towards smaller values. Stable, finite energy, abelian magnetic solutions exist only for a specific range of threshold correction parameters. At small scales they correspond to the strong coupling region (φ → ∞) and the compactification region (ϕ → 0). The non-perturbative potential V plays a crucial role at large scales, where it fixes the asymptotic values of φ and ϕ to be at the minimum of V .

We generalize the boundary value problem with a mixed boundary condition that involves the gauge and scalar fields in the context of Einstein-Maxwell-Dilaton theories. In particular, the expectation value of the dual scalar operator can be a function of the expectation value of the current operator. The properties are prevalent in a fixed charge ensemble because the conserved charge is shared by both fields through the dilaton coupling, which is also responsible for non-Fermi liquid properties. We study the on-shell action and the stress energy tensor to note practical importances of the boundary value problem. In the presence of the scalar fields, physical quantities are not fully fixed due to the finite boundary terms that manifest in the massless scalar or the scalar with mass saturating the Breitenlohner-Freedman bound.
