New preprint: memory-gated anomalous transport out of equilibrium

Congratulations to Pranay, Tianchu, and Srijan for their new preprint, “Memory-gated transient anomalous transport of quasiparticles out of equilibrium,” now on arXiv! Using the dispersive Holstein model of small polarons, the paper shows that a single signed bath memory time determines whether carriers far from equilibrium move subdiffusively or superdiffusively, and by how much. Tuning the environment from resonant to off-resonant with the carriers flips transport from subdiffusion to superdiffusion, pointing to a way to control nonequilibrium quasiparticle flow by engineering the environment.
