GPS constellation search for exotic physics messengers coincident with the binary neutron star merger GW170817
Arko P. Sen, Geoffrey Blewitt, Andrey Sarantsev +2
The Global Positioning System (GPS) includes a continuously operating, planet-scale network of atomic clocks that, beyond navigation and time dissemination, enables precision tests…
Tutorial on running median subtraction filter with application to searches for exotic field transients in multi-messenger astronomy
Arko P. Sen, Andrey Sarantsev, Geoffrey Blewitt +1
Running Median Subtraction Filter (RMSF) is a robust statistical tool for removing slowly varying baselines in data streams containing transients (short-duration signals) of intere…
Convergence rate to equilibrium in Wasserstein distance for reflected jump-diffusions
Andrey Sarantsev
Convergence rate to the stationary distribution for continuous-time Markov processes can be studied using Lyapunov functions. Recent work by the author provided explicit rates of c…
Talagrand Concentration Inequalities for Stochastic Partial Differential Equations
Davar Khoshnevisan, Andrey Sarantsev
One way to define the concentration of measure phenomenon is via Talagrand inequalities, also called transportation-information inequalities. That is, a comparison of the Wasserste…
Yet Another Condition for Absence of Collisions for Competing Brownian Particles
Tomoyuki Ichiba, Andrey Sarantsev
Consider a finite system of rank-based competing Brownian particles, where the drift and diffusion of each particle depend only on its current rank relative to other particles. We…
Stationary Gap Distributions for Infinite Systems of Competing Brownian Particles
Andrey Sarantsev, Li-Cheng Tsai
Consider the infinite Atlas model: a semi-infinite collection of particles driven by independent standard Brownian motions with zero drifts, except for the bottom-ranked particle w…
Two-Sided Infinite Systems of Competing Brownian Particles
Andrey Sarantsev
Two-sided infinite systems of Brownian particles with rank-dependent dynamics, indexed by all integers, exhibit different properties from their one-sided infinite counterparts, ind…
Infinite Systems of Competing Brownian Particles
Andrey Sarantsev
Consider a system of infinitely many Brownian particles on the real line. At any moment, these particles can be ranked from the bottom upward. Each particle moves as a Brownian mot…
Triple and Simultaneous Collisions of Competing Brownian Particles
Andrey Sarantsev
Consider a finite system of competing Brownian particles on the real line. Each particle moves as a Brownian motion, with drift and diffusion coefficients depending only on its cur…
Multiple Collisions in Systems of Competing Brownian Particles
Cameron Bruggeman, Andrey Sarantsev
Consider a finite system of competing Brownian particles on the real line. Each particle moves as a Brownian motion, with drift and diffusion coefficients depending only on its cur…
Comparison Techniques for Competing Brownian Particles
Andrey Sarantsev
Consider a finite system of Brownian particles on the real line. Each particle has drift and diffusion coefficients depending on its current rank relative to other particles, as in…
