Determination of thermodynamics from entanglement entropy in the finite-density O(N) model
Niko Jokela, Aatu Rajala, Tobias Rindlisbacher
We nonperturbatively compute Rényi entropies for strip-shaped subregions in the three-dimensional O(4) model at finite density on the lattice. By using a dual variable representat…
Lattice studies of entanglement entropy in models at finite densities
Aatu Rajala, Niko Jokela, Tobias Rindlisbacher
As a characteristic property of all quantum systems, entanglement participates in many important quantum phenomena. In this proceeding, we employ it in the study of quantum field t…
Testing the effective action approach to bubble nucleation in holography
Oscar Henriksson, Niko Jokela, Xin Li
The nucleation of bubbles during a first-order phase transition has recently been explored using holographic duality, which can provide an important complement to standard perturba…
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…
Thermal and chemical response from entanglement entropy
Niko Jokela, Aatu Rajala, Tobias Rindlisbacher
We study entanglement entropy (EE) in interacting quantum field theories (QFTs) at finite density. We argue that, in the limit of large subregions, the derivative of EE with respec…
