Symmetry-allowed phase transitions realized by the two-dimensional fully frustrated XY class
Petter Minnhagen, Beom Jun Kim, Sebastian Bernhardsson +1
A 2D Fully Frustrated XY(FFXY) class of models is shown to contain a new groundstate in addition to the checkerboard groundstates of the standard 2D FFXY model. The spin configurat…
The Blind Watchmaker Network: Scale-freeness and Evolution
Petter Minnhagen, Sebastian Bernhardsson
It is suggested that the degree distribution for networks of the cell-metabolism for simple organisms reflects an ubiquitous randomness. This implies that natural selection has exe…
Phase diagram of generalized fully frustrated XY model in two dimensions
Petter Minnhagen, Beom Jun Kim, Sebastian Bernhardsson +1
It is shown that the phase diagram of the two-dimensional generalized fully-frustrated XY model on a square lattice contains a crossing of the chirality transition and the Kosterli…
Optimization and Scale-freeness for Complex Networks
Petter Minnhagen, Sebastian Bernhardsson
Complex networks are mapped to a model of boxes and balls where the balls are distinguishable. It is shown that the scale-free size distribution of boxes maximizes the information…
One Hub-One Process: A Tool Based View on Regulatory Network Topology
Jacob Bock Axelsen, Sebastian Bernhardsson, Kim Sneppen
The relationship between the regulatory design and the functionality of molecular networks is a key issue in biology. Modules and motifs have been associated to various cellular pr…
