NS5-branes on an ellipsis and novel marginal deformations with parafermions
P. Marios Petropoulos, Konstadinos Sfetsos
We consider NS5-branes distributed along the circumference of an ellipsis and explicitly construct the corresponding gravitational background. This provides a continuous line of de…
Renormalization-group flows and charge transmutation in string theory
Domenico Orlando, P. Marios Petropoulos, Konstadinos Sfetsos
We analyze the behaviour of heterotic squashed-Wess-Zumino-Witten backgrounds under renormalization-group flow. The flows we consider are driven by perturbation creating extra gaug…
Three-dimensional black holes from deformed anti-de Sitter
Stephane Detournay, Domenico Orlando, P. Marios Petropoulos +1
We present new exact three-dimensional black-string backgrounds, which contain both NS--NS and electromagnetic fields, and generalize the BTZ black holes and the black string studi…
