New Paper: Mitigating long queues and waiting times with service resetting
We demonstrate how service resetting can dramatically lower waiting times and improve overall performance of queueing systems (natural and man-made). Random service time fluctuations are notorious for causing major backlogs and delays in such systems. Yet, we show that when these fluctuations are intrinsic to the server—a remarkably simple service resetting protocol can reverse their deleterious effects and significantly cut down queues and waits.

New Paper: Gated Reactions in Discrete Time and Space
A unified, continuous-time, approach to gated reactions on networks was presented in Phys. Rev. Lett. 127, 018301, (2021). We build on this recent advancement to present an analogous discrete-time version of the theory. We show that the discretization of time gives rise to resonances and anti-resonances, which were absent from the continuous-time picture. These features are illustrated using two case studies that are also used to demonstrate how the developed approach greatly simplifies the analysis of gated reactions.

New Paper: The Inspection Paradox in Stochastic Resetting
Passengers arriving at a bus stop at a random time may on average wait longer than the mean time between bus arrivals—a counter-intuitive result, since one expects to wait less when coming some time after the previous bus departed. We review the origins of this phenomenon, a.k.a. the inspection paradox, and use the insight gained to explain why, and under which conditions, stochastic resetting expedites the completion of random processes: from search to chemical reactions.
