Scaling limits of a model for selection at two scales [PDF]
Nonlinearity, 2017 Abstract The dynamics of a population undergoing selection is a central topic in evolutionary biology. This question is particularly intriguing in the case where selective forces act in opposing directions at two population scales. For example, a fast-replicating virus strain outcompetes slower-replicating strains

Spectral form factor in the τ-scaling limit
Journal of High Energy Physics, 2023 We study the spectral form factor (SFF) of general topological gravity in the limit of large time and fixed temperature. It has been observed recently that in this limit, called the tau-scaling limit, the genus expansion of the SFF can be summed up and ...

Finite temperature QCD phase transition and its scaling window from Wilson twisted mass fermions [PDF]
EPJ Web of Conferences, 2022 We study the properties of finite temperature QCD using lattice simulations with Nf = 2 + 1 + 1 Wilson twisted mass fermions for pion masses from physical up to heavy quark regime.

Complex Sachdev-Ye-Kitaev model in the double scaling limit
Journal of High Energy Physics, 2021 We solve for the exact energy spectrum, 2-point and 4-point functions of the complex SYK model, in the double scaling limit at all energy scales. This model has a U(1) global symmetry.

Scaling Limits for the Generalized Langevin Equation [PDF]
Journal of Nonlinear Science, 2021 In this paper, we study the diffusive limit of solutions to the generalized Langevin equation (GLE) in a periodic potential. Under the assumption of quasi-Markovianity, we obtain sharp longtime equilibration estimates for the GLE using techniques from the theory of hypocoercivity. We then prove asymptotic results for the effective diffusion coefficient

Entanglement of magnon excitations in spin chains
Journal of High Energy Physics, 2022 We calculate exactly the entanglement content of magnon excited states in the integrable spin-1/2 XXX and XXZ chains in the scaling limit. In particular, we show that as far as the number of excited magnons with respect to the size of the system is small

The limits of fine‐scale mapping [PDF]
Genetic Epidemiology, 2008 AbstractWhen a novel genetic trait arises in a population, it introduces a signal in the haplotype distribution of that population. Through recombination that signal's history becomes differentiated from the DNA distant to it, but remains similar to the DNA close by. Fine‐scale mapping techniques rely on this differentiation to pinpoint trait loci.
