Effects of string cloud on Gauss-Bonnet holographic superconductors Cao H. Nam Institute of Research and Development, Duy Tan University, Da Nang 550000, Vietnam a r t i c l e i n f o a b s t r a c t Article history: The effects of the string cloud on higher-dimensional holographic superconductors in Einstein-Gauss- Received 13 June 2019 Bonnet gravity are investigated in the probe limit. The critical temperature is analytically obtained using Received in revised form 21 July 2019 Sturm-Liouville eigenvalue method. It is observed that the critical temperature only exists in an allowed Accepted 12 August 2019 region of the parameter space. Also, the presence of the string cloud with the sufficiently large density Available online 19 August 2019 should prevent the existence of the critical temperature. As increasing the string cloud dens
