Holographic surface defect RG flows without supersymmetry
José Manuel Penín, James Ratcliffe, Ronnie Rodgers +1
We consider supersymmetric Yang--Mills theory with gauge group SU, which admits families of conformal surface defects defined by singular boundary conditions f…
Holomorphic D-brane embeddings in D-brane backgrounds
James Ratcliffe, Ronnie Rodgers, Sangsoo Ryu
We describe families of probe D-brane embeddings in the extremal black D-brane backgrounds of type IIA and type IIB supergravity, specified by an arbitrary holomorphic functi…
Entanglement C-functions of defects and interfaces in supersymmetric Yang-Mills theory
Niko Jokela, Jani Kastikainen, José Manuel Penín +2
We consider planar codimension-one defects and interfaces in supersymmetric Yang-Mills (SYM) theory, realized by the D3/D5-brane intersection. Working in the probe…
Entanglement and Excitations in Gauge/Gravity Duality
Ronnie Rodgers
In this thesis, we study a variety of phenomena in strongly coupled quantum field theories by performing calculations in their gravitational duals. We compute entanglement entropy…
