Lattice models in Florence
At the top of a hill south east of Florence, at the end of a long boulevard climbing up through pine, cypress and oak trees, is the Galileo Galilei Institute for Theoretical Physics. Cats doze by the steps leading up… Read More ›

Mathematics for the fluid Earth
JPhysA are now accepting submissions for a new special issue on mathematics for the fluid Earth. The Earth is a rich system in which to study fluid mechanics, nonequilibrium statistical mechanics, nonlinearities and random processes, so we expect to get a very diverse spread of papers within the scope of the journal.

Fast Track Communications in JPhysA

Image of the week: hidden attractors
These dragonflylike patterns are chaotic and quasiperiodic states in a radiophysical oscillator system. In their recent JPhysA paper, Kuznetsov and colleagues have investigated where these dynamics appear in a system that doesn’t have an equilibrium point, where one wouldn’t naturally expect to find this type of behaviour.

Dorje Brody: quantum mechanics meets mathematical finance

Publisher’s Pick: Rafael Nepomechie
In this Publisher’s Pick article, Rafael Nepomechie explains how preparing a student exercise led to new insights in how to select physical solutions to a particular spin chain, and consequently a paper in JPhysA.

Funniest preprint title this week
Christopher Ferrie and Richard Kueng get a chuckle for naming their preprint Have you been using the wrong estimator? These guys bound average fidelity using this one weird trick von Neumann didn’t want you to know. Sadly, the paper doesn’t contain 31 gifs of quantum states that prove you were a 90s kid.
