Balls in Boxes (ZRP)

Some forays have also been made into solvable nonequilibrium models such as the ASEP (Asymmmetric Exclusion Process) and ZRP (Zero Range Process) with Richard Blythe at Edinburgh University and Piotr Bialas and Zdzislaw Burda in Krakow. This even spilled over into "econophysics" with the Polish collaborators. Revisited more recently to calculate the Renyi entropy of a balls in boxes model.
