Bose polarons in the strongly interacting regime
When an impurity is immersed in a Bose-Einstein condensate, impurity-boson interactions
are expected to dress the impurity into a quasiparticle, the Bose polaron. We superimpose …

One-dimensional quantum liquids: Beyond the Luttinger liquid paradigm
A Imambekov, TL Schmidt, LI Glazman - Reviews of Modern Physics, 2012 - APS
For many years, the Luttinger liquid theory has served as a useful paradigm for the
description of one-dimensional (1D) quantum fluids in the limit of low energies. This theory is …
