Entanglement C-functions of defects and interfaces in supersymmetric Yang-Mills theory
Niko Jokela, Jani Kastikainen, José Manuel PenÃn +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…

Covariant unification of holographic c-functions
Niko Jokela, Jani Kastikainen, Carlos Nunez +2
We propose a covariant holographic c-function, defined directly in a top-down background and constructed from the extrinsic curvature of codimension-two slices of the bulk geometry…

On entanglement c-functions in confining gauge field theories
Niko Jokela, Jani Kastikainen, Carlos Nunez +3
Entanglement entropy has proven to be a powerful tool for probing renormalization group (RG) flows in quantum field theories, with c-functions derived from it serving as candidate…
