Nonequilibrium statistical physics

Fluctuation spectra and force generation in non-equilibrium systems
We argue that a general signature of active and driven non-equilibrium systems is a non-trivial fluctuation spectrum. This physical insight allows us to construct a unifying up-down framework that can describe a plethora of seemingly disparate non-equilibrium phenomena.
Kinetics of self-assembling systems
Dissecting the self-assembly kinetics of multimeric pore-forming toxins
Pore-forming toxins are polymeric cytotoxins used by both bacteria and the immune system that kill cells by forming pores on the cell membrane. Experiments that track the formation of a single pore reveal that pore formation is surprising fast, yet partially-formed pores are not seen. In this paper, we developed a model for pore formation that explains those observations. Moreover, our mathematical model provides insights to hindering the action of pore-forming toxins in bacteria.
Sharp interface limits of the Cahn-Hilliard Equation with degenerate mobility
We analysed the Cahn-Hilliard Equation with degenerate mobility using formal matched asymptotics. The analysis showed that the long-time sharp interface limit is not given by the so-called surface diffusion model, as was assumed in all previous literature.
