Universality in the target arrival statistics of non-conservative search processes
José Giral-Barajas, Samantha Linn, Paul C. Bressloff
Stochastic search processes in which searchers are continuously introduced to and removed from a target search domain are fundamental to a wide class of physical and artificial sys…
Dynamic redundancy and mortality in stochastic search
Samantha Linn, Aanjaneya Kumar
Search processes are a fundamental part of natural and artificial systems. In such settings, the number of searchers is rarely constant: new agents may be recruited while others ca…
Renewal theory for a run-and-tumble particle with stochastic resetting and a sticky boundary
Paul C Bressloff, Samantha Linn
We consider a run-and-tumble particle (RTP) with stochastic resetting confined to the half line with a sticky boundary at . In the bulk the RTP tumbles at a const…
Cover times with stochastic resetting
Samantha Linn, Sean D Lawley
Cover times quantify the speed of exhaustive search. In this work, we compute exactly the mean cover time associated with a one-dimensional Brownian search under exponentially dist…
Hitting probabilities for fast stochastic search
Samantha Linn, Sean D. Lawley
Many physical phenomena are modeled as stochastic searchers looking for targets. In these models, the probability that a searcher finds a particular target, its so-called hitting p…
