Threshold singularities in onedimensional metals The lowenergy behaviour of generic critical onedimensional quantum systems is usually described within the Luttinger liquid theory. It simplifies the real system by replacing the true energymomentum relation for its particles by a linear one. Precisely because of band curvature effects Luttinger liquid theory  despite its remarkable success for thermodynamic properties  breaks down when we are interested in singularities in dynamical response functions. Recent developments using a mapping to a Luttinger liquid with an additional high frequency mobile impurity permit the description of effects due to the spectral nonlinearity. We give an introduction to the theory of nonlinear Luttinger liquids and present a constructive derivation of a mobile impurity model for spin1/2 fermions.

What Shape and Motion Talk: Physics of Human Diseases Diseases and development are highly complex, stochastic processes in nature. For example, the morphological dynamics of metastatic cancer cells during migration is highly stochastic. The combination of quantitative in vitro models, live cell imaging, and statistical physics gives us a powerful tool to experimentally unravel characteristic spatiotemporal information behind the stochastic noise, which is not accessible with phenomenological observation.
