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…
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…
Confined-deconfined interface tension and latent heat in SU(N) gauge theory
Tobias Rindlisbacher, Kari Rummukainen, Ahmed Salami
We present high-precision lattice results for the confined-deconfined interface tension and the latent heat of pure SU() gauge theories up to and investigate their asympt…
Evaluating matrix power series with the Cayley-Hamilton theorem
Tobias Rindlisbacher
The Cayley-Hamilton theorem is used to implement an iterative process for the efficient numerical computation of matrix power series and their differentials. In addition to straigh…
The confined-deconfined surface tension in SU(N) gauge theories at large N
Tobias Rindlisbacher, Kari Rummukainen, Ahmed Salami
We present results from an investigation of the -dependency of the confined-deconfined interface tension and latent heat in pure SU() gauge theory at large . The interface…
