Perfect State Transfer on Signed Graphs
J. Brown, C. Godsil, D. Mallory +2
We study perfect state transfer of quantum walks on signed graphs. Our aim is to show that negative edges are useful for perfect state transfer. Specific results we prove include:…
On non-existence of global solutions to a class of stochastic heat equations
Mohammud Foondun, Rana Parshad
We consider nonlinear parabolic SPDEs of the form , where denotes space-time white noise. The functions and are both…
Effects of degree-frequency correlations on network synchronization: universality and full phase-locking
Per Sebastian Skardal, Jie Sun, Dane Taylor +1
We introduce a model to study the effect of degree-frequency correlations on synchronization in networks of coupled oscillators. Analyzing this model, we find several remarkable ch…
Spectral properties of zero temperature dynamics in a model of a compacting granular column
L. S. Schulman, J. M. Luck, Anita Mehta
The compacting of a column of grains has been studied using a one-dimensional Ising model with long range directed interactions in which down and up spins represent orientations of…
