Is the Aharonov-Casher phase geometrical or dynamical?

Igor Kuzmenko, Y. B. Band, Yshai Avishai

We consider two two-dimensional (2D) electronic systems in the presence of a perpendicular homogeneous electric field that generates a Rashba spin-orbit interaction (RSOI): a syste…

Proximity Measures for Classes of Phylogenetic Networks

Leo van Iersel, Mark Jones, Esther Julien +2

The paper defines and analyzes proximity measures that quantify how many graph modifications are needed to convert a phylogenetic network into a member of specific network classes…

Bounds on the sequence length sufficient to reconstruct binary level- phylogenetic networks under the CFN model

Martin Frohn, Niels Holtgrefe, Leo van Iersel +2

Phylogenetic trees and networks are graphs used to model evolutionary relationships, with trees representing strictly branching histories and networks allowing for events in which…

Exact and Heuristic Computation of the Scanwidth of Directed Acyclic Graphs

Niels Holtgrefe, Leo van Iersel, Mark Jones

To measure the tree-likeness of a directed acyclic graph (DAG), a new width parameter that considers the directions of the arcs was recently introduced: scanwidth. We present the f…

Characterizing semi-directed phylogenetic networks and their multi-rootable variants

Niels Holtgrefe, Katharina T. Huber, Leo van Iersel +2

In evolutionary biology, phylogenetic networks are graphs that provide a flexible framework for representing complex evolutionary histories that involve reticulate evolutionary eve…

When are quarnets sufficient to reconstruct semi-directed phylogenetic networks?

Katharina T. Huber, Leo van Iersel, Mark Jones +2

Phylogenetic networks are graphs that are used to represent evolutionary relationships between different taxa. They generalize phylogenetic trees since for example, unlike trees, t…
