Uncertainty Quantification for Markov Processes via Variational Principles and Functional Inequalities
Jeremiah Birrell, Luc Rey-Bellet
Information-theory based variational principles have proven effective at providing scalable uncertainty quantification (i.e. robustness) bounds for quantities of interest in the pr…

Langevin equations in the small-mass limit: Higher-order approximations
Jeremiah Birrell, Jan Wehr
We study the small-mass (overdamped) limit of Langevin equations for a particle in a potential and/or magnetic field with matrix-valued and state-dependent drift and diffusion. We…

Temperature Dependence of the Neutron Lifespan
Cheng Tao Yang, Jeremiah Birrell, Johann Rafelski
Current precision big bang nucleosynthesis (BBN) studies motivate us to revisit the neutron lifespan in the plasma medium of the early universe. The mechanism we explore is the Fer…
