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…
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…
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…
Flavors of entanglement
Niko Jokela, Jani Kastikainen, José Manuel Penín +1
We employ holography to investigate Liu-Mezei renormalization group monotones in conformal field theories influenced by massive flavor degrees of freedom. We examine the entangleme…
Limitations of entanglement entropy in detecting thermal phase transitions
Niko Jokela, Helime Ruotsalainen, Javier G. Subils
We explore the efficacy of entanglement entropy as a tool for detecting thermal phase transitions in a family of gauge theories described holographically. The rich phase diagram of…
