An integrable deformation of the sine(sinh)-Gordon model -- Malcev algebra
Meseret Asrat
In this paper we present an integrable model in two dimensions. It is a deformation of the sine(sinh)-Gordon model. We give its Lax connection. We also obtain its (classical) -m…

Thermal/Black hole phase transition and entanglement entropy in (2 + 1)D
Meseret Asrat
We consider a one parameter family of holographic solutions in classical string theory in three spacetime dimensions. In Euclidean space, the solutions interpolate smoothly without…

Kalb-Ramond field, black holes and black strings in (2 + 1)D
Meseret Asrat
New rotating dilaton black hole and black string solutions in three spacetime dimensions are obtained. The background spacetime interpolates between Anti-de Sitter and a (an asympt…
