First-passage resetting gas
Marco Biroli, Satya N. Majumdar, Grégory Schehr
Europhysics Letters 153, 31002
A gas of Brownian particles whose collective reset is triggered by a first-passage event — the first one to reach a threshold drags the others back. Correlations, stationary density, and extreme-value statistics in this first-passage-coupled setting.
2026
Dynamically emergent correlations in Brownian particles subject to simultaneous non-Poissonian resetting protocols
Gabriele de Mauro, Marco Biroli, Satya N. Majumdar, Grégory Schehr
Physical Review E 113, 014120
Generalizes the correlated Brownian gas to non-Poissonian resetting protocols — deterministic, power-law, heavy-tailed. The shape of the inter-reset distribution reshapes the correlation structure.
2025
Experimental evidence for strong emergent correlations between particles in a switching trap
Marco Biroli, Sergio Ciliberto, Manas Kulkarni, Satya N. Majumdar, Artyom Petrosyan, Grégory Schehr
arXiv preprint
An optical-tweezers experiment that directly measures the emergent correlations predicted for particles in a stochastically switching trap — the first experimental realization of the mechanism.
2025
Resetting Dyson Brownian motion
Marco Biroli, Satya N. Majumdar, Grégory Schehr
Physical Review E 112, 014101
Dyson Brownian motion of N eigenvalues, reset simultaneously. Stationary density, extreme-eigenvalue statistics, and the crossover between resetting-dominated and repulsion-dominated regimes.
2025
Strongly correlated stochastic systems
Marco Biroli
arXiv preprint (PhD thesis / review)
A unified review of the strongly-correlated stochastic systems that motivated the papers above: resetting as a correlation-generating mechanism, exactly solvable gas models, extreme and order statistics in the correlated regime.
2024
Exact extreme, order, and sum statistics in a class of strongly correlated systems
Marco Biroli, Hernán Larralde, Satya N. Majumdar, Grégory Schehr
Physical Review E 109, 014101
A class of strongly correlated systems where the joint distribution factorizes after conditioning on a single random variable — enabling closed-form extreme, order, and sum statistics.
2024
Resetting by rescaling: exact results for a diffusing particle in one dimension
Marco Biroli, Yannick Feld, Alexander K. Hartmann, Satya N. Majumdar, Grégory Schehr
Physical Review E 110, 044142
A diffusing particle whose position is rescaled (rather than reset to the origin) at Poisson events. Exact stationary distribution and large-deviation tails, with numerical checks.
2024
Dynamically emergent correlations between particles in a switching harmonic trap
Marco Biroli, Manas Kulkarni, Satya N. Majumdar, Grégory Schehr
Physical Review E 109, L032106
Non-interacting particles in a harmonic trap whose stiffness switches stochastically develop non-trivial correlations purely from the shared environmental noise.
2023
Critical number of walkers for diffusive search processes with resetting
Marco Biroli, Satya N. Majumdar, Grégory Schehr
Physical Review E 107, 064141
For N searchers independently diffusing with resetting, the mean first-passage time to a target has a non-monotonic dependence on N — we characterize the critical number of walkers below which a single fast walker beats the crowd.
2023
Extreme statistics and spacing distribution in a Brownian gas correlated by resetting
Marco Biroli, Hernán Larralde, Satya N. Majumdar, Grégory Schehr
Physical Review Letters 130, 207101
N Brownian particles on a line, each simultaneously reset to the origin at rate r. The shared resetting event alone correlates otherwise-independent particles; we derive the resulting order-statistics and spacing distributions in closed form.
2022
Number of distinct sites visited by a resetting random walker
Marco Biroli, Francesco Mori, Satya N. Majumdar
Journal of Physics A 55, 244001
Exact results for the mean and full distribution of the number of distinct sites visited by a lattice random walker subject to stochastic resetting.
2022
Time, privacy, robustness, accuracy: trade-offs for the open vote network protocol
Fatima-Ezzahra El Orche, Rémi Géraud-Stewart, Peter B. Rønne, Gergei Bana, David Naccache, Peter YA Ryan, Marco Biroli, Megi Dervishi, Hugo Waltsburger
E-Vote-ID 2022 (LNCS 13553)
A cryptography / e-voting paper from an earlier collaboration: analysis of the open vote network protocol along the axes of time, privacy, robustness, and accuracy.
