The orbit method solution for the deformed three coupled scalar fields
In this work, we present a deformed solutions starting from systems of three
coupled scalar fields with super-potential by orbit
method. First, we deform the corresponding super-potential and obtain defect
solutions. It is shown that how to construct new models altogether with its
defect solutions in terms of the non-deformed model. Therefore, we draw the
graph of super-potential and different fields in terms of So we observe
that the graphs for deformed and non - deformed cases are changed by the scale.Comment: 9 pages, 5 figure
Thermodynamics of string black hole with hyperscaling violation
In this paper, we start with black brane and construct specific space-time
which violates hyperscaling. In order to obtain the string solution we apply
Null-Melvin-Twist and -reduction. By using the difference action method we
study thermodynamics of system to obtain Hawking-Page phase transition. In
order to have hyperscaling violation we need to consider
In that case the free energy is always negative and our solution is thermal
radiation without a black hole. Therefore we find that there is not any
Hawking-Page transition. Also, we discuss the stability of system and all
thermodynamical quantities.Comment: 12 pages. Accepted for publication in EPJ
