On large deviations for the range of a two-dimensional random walk
Serguei Popov, Quirin Vogel
In this note, we compute the probability that a two-dimensional symmetric random walk visits more vertices than expected, for deviations on scales between the mean behavior and lin…

1+O(1) asymptotics for loop percolation in five and higher dimensions
Quirin Vogel
We calculate the one-arm probability and the two-point function for loop percolation in dimensions five and higher on the lattice up to first order. This answers a question posed b…

Phase Transitions in a Particle Model for the Self-Adaptive Response to Cancer Dynamics
Christian Kuehn, Quirin Vogel
In this paper, we present a probabilistic analysis of a dynamical particle model for the self-adaptive immune response to cancer, as proposed by the first author in a previous work…
