The Wess-Zumino-Novikov-Witten spin-chain -model
Roberto Ruiz
The Wess-Zumino-Novikov-Witten model realises bosonic-string theory in with pure Neveu-Schwarz-Neveu-Schwarz flux. We construct an ef…
Quantum corrections to minimal surfaces with mixed three-form flux
Rafael Hernandez, Juan Miguel Nieto, Roberto Ruiz
We obtain the ratio of semiclassical partition functions for the extension under mixed flux of the minimal surfaces subtending a circumference and a line in Euclidean $AdS_{3}\time…
The Wess-Zumino-Witten spin chain sigma model
Rafael Hernandez, Juan Miguel Nieto, Roberto Ruiz
Classical strings propagating in supported with Neveu-Schwarz-Neveu-Schwarz flux are described by a Wess-Zumino-Witten model. In this note, we stu…
Minimal surfaces with mixed three-form flux
Rafael Hernandez, Juan Miguel Nieto, Roberto Ruiz
We study minimal area world sheets ending on two concentric circumferences on the boundary of Euclidean with mixed R-R and NS-NS three-form fluxes. We solve the problem b…
One-loop quantization of rigid spinning strings in with mixed flux
Juan Miguel Nieto, Roberto Ruiz
We compute the one-loop correction to the classical dispersion relation of rigid closed spinning strings with two equal angular momenta in the backgro…
Pulsating strings with mixed three-form flux
Rafael Hernandez, Juan Miguel Nieto, Roberto Ruiz
Circular strings pulsating in with mixed R-R and NS-NS three-form fluxes can be described by an integrable deformation of the one-dimensional Neumann-…
