Directed Spatial Permutations on Asymmetric Tori

Alan Hammond, Tyler Helmuth

We investigate a model of random spatial permutations on two-dimensional tori, and establish that the joint distribution of large cycles is asymptotically given by the Poisson--Dir…

On the Trail of Lost Pennies: player-funded tug-of-war on the integers

Alan Hammond

We study random-turn resource-allocation games. In the Trail of Lost Pennies, a counter moves on . At each turn, Maxine stakes and Mina $b \in [0,\in…

Stake-governed tug-of-war and the biased infinity Laplacian

Yujie Fu, Alan Hammond, Gábor Pete

In tug-of-war, two players compete by moving a counter along edges of a graph, each winning the right to move at a given turn according to the flip of a possibly biased coin. The g…

Collapse and Diffusion in Harmonic Activation and Transport

Jacob Calvert, Shirshendu Ganguly, Alan Hammond

For an -element subset of , select from according to harmonic measure from infinity, remove from , and start a random walk from . If the walk…

Beyond-mean-field effects in Rabi-coupled two-component Bose-Einstein condensate

L Lavoine, A Hammond, A Recati +2

We theoretically calculate and experimentally measure the beyond-mean-field (BMF) equation of state in a coherently-coupled two-component Bose-Einstein condensate (BEC) in the regi…

Exceptional times when the KPZ fixed point violates Johansson's conjecture on maximizer uniqueness

Ivan Corwin, Alan Hammond, Milind Hegde +1

In 2002, Johansson conjectured that the maximum of the Airy process minus the parabola is almost surely achieved at a unique location. This result was proved a decade lat…
