Supersymmetry and stationary solutions in dilaton-axion gravity
Gravity is fixed charged Taub - the NUT steel pipe concrete the construction
font style='font-size:12px;'>
2014/12/23
New stationary solutions of four-dimensional dilaton-axion gravity are presented, which correspond to the charged Taub-NUT and Israel-Wilson-Perjés (IWP) solutions of Einstein-Maxwell theory. The char...
Pair creation of dilaton black holes
Theory of gravity time and space dimensions coupling a black hole magnetism
font style='font-size:12px;'>
2014/12/23
We consider dilaton gravity theories in four spacetime dimensions parametrized by a constant a, which controls the dilaton coupling, and construct new exact solutions. We first generalize the C metric...
Equivalence Principle Violations and Couplings of a Light Dilaton
Exchange of light coupling inverse cubic root atoms scalar coupling parameterized
font style='font-size:12px;'>
2014/12/18
We consider possible violations of the equivalence principle through the exchange of a light “dilaton-like” scalar field. Using recent work on the quark-mass dependence of nuclear binding, we find tha...
Solutions of the dilaton field equations with applications to the soliton-black hole correspondence in generalised JT gravity

I construct solutions to the heterotic supergravity BPS-equations on products of Minkowski space with a non-symmetric coset. All of the bosonic fields are homogeneous and non-vanishing, the dilaton be...

2010/12/24
We calculate the free energy, spatial string tension and Polyakov loop of the gluon plasma using the dilaton potential of Ref. arXiv:0911.0627[hep-ph] in the dilaton-gravity theory of AdS/QCD. The fr...

2010/12/24
The implications for the Dilaton stabilization problem are investigated when the effective potential for this field is generated by the existence of a massive fermion. The previously evaluated two lo...

Bogomol'nyi bound Einstein-Maxwell-dilaton gravity
font style='font-size:12px;'>
2010/12/21
It has been shown that the Einstein-Maxwell-dilaton theory allows a Bogomol’nyi-type inequality
for an arbitrary dilaton coupling constant , and that the bound is saturated if and only if the
