Geometric Flow Description of Minimal Surfaces
Dimitrios Katsinis, Ioannis Mitsoulas, Georgios Pastras
We introduce a description of a minimal surface in a space with boundary, as the world-hypersurface that the entangling surface traces. It does so by evolving from the boundary to…
An Inverse Mass Expansion for the Mutual Information in Free Scalar QFT at Finite Temperature
Dimitrios Katsinis, Georgios Pastras
We study the entanglement entropy and the mutual information in coupled harmonic systems at finite temperature. Interestingly, we find that the mutual information does not vanish a…
Area Law Behaviour of Mutual Information at Finite Temperature
Dimitrios Katsinis, Georgios Pastras
Entanglement entropy in free scalar field theory at its ground state is dominated by an area law term. However, when mixed states are considered this property ceases to exist. We s…
Stability Analysis of Classical String Solutions and the Dressing Method
Dimitrios Katsinis, Ioannis Mitsoulas, Georgios Pastras
The dressing method is a technique to construct new solutions in non-linear sigma models under the provision of a seed solution. This is analogous to the use of autoBacklund transf…
Salient Features of Dressed Elliptic String Solutions on S
Dimitrios Katsinis, Ioannis Mitsoulas, Georgios Pastras
We analyse several physical aspects of the dressed elliptic strings propagating on and of their counterparts in the Pohlmeyer reduced theory, i.e.…
