RT Journal Article T1 Minimal surfaces with mixed three-form flux A1 Hernández Redondo, Rafael A1 Nieto García, Juan Miguel A1 Ruiz Gil, Roberto AB We study minimal area world sheets ending on two concentric circumferences on the boundary of Euclidean AdS_3 with mixed Ramond-Ramond and Neveu-Schwarz-Neveu-Schwarz (NS-NS) three-form fluxes. We solve the problem by reducing the system to a one-dimensional integrable model. We find that the NS-NS flux term either brings the surface near to the boundary or separates the circumferences. In the limit of pure NS-NS flux, the solution adheres to the boundary in the former case, and the outer radius diverges in the latter. We further construct the underlying elliptic spectral curve, which allows us to analyze the deformation of other related minimal surfaces. We show that in the regime of pure NS-NS flux the elliptic curve degenerates.
