Exponential distance relation (aka Titius-Bode rule) in extra solar planetary systems
Dimitrios Krommydas, Fabio Scardigli
In this paper we present phenomenological evidence for the validity of an exponential distance relation (also known as generalized Titius-Bode law) in the 32 planetary systems (31…
Hydrodynamic Enhancement of -atic Defect Dynamics
Dimitrios Krommydas, Livio Nicola Carenza, Luca Giomi
We investigate numerically and analytically the effects of hydrodynamics on the dynamics of topological defects in atic liquid crystals, i.e. two-dimensional liquid crystals wi…
Epithelia are multiscale active liquid crystals
Josep-Maria Armengol-Collado, Livio Nicola Carenza, Julia Eckert +2
Biological processes such as embryogenesis, wound healing and cancer progression, crucially rely on the ability of epithelial cells to coordinate their mechanical activity over len…
A singularity theorem for evaporating black holes
Eleni-Alexandra Kontou, Ben Freivogel, Dimitrios Krommydas
The classical singularity theorems of General Relativity rely on energy conditions that are easily violated by quantum fields. Here, we provide motivation for an energy condition o…
The Return of the Singularities: Applications of the Smeared Null Energy Condition
Ben Freivogel, Eleni-Alexandra Kontou, Dimitrios Krommydas
The classic singularity theorems of General Relativity rely on energy conditions that can be violated in semiclassical gravity. Here, we provide motivation for an energy condition…
The Smeared Null Energy Condition
Ben Freivogel, Dimitrios Krommydas
We propose a new bound on the average null energy along a finite portion of a null geodesic. We believe our bound is valid on scales small compared to the radius of curvature in an…
Violations of the Null Energy Condition in QFT and their Implications
Dimitrios Krommydas
We study violations of the Null Energy Condition (NEC) in Quantum Field Theory (QFT) and their implications. For the first part of the project, we examine these violations for clas…
