Critical velocity of a mobile impurity in one-dimensional quantum liquids
Michael Schecter, Alex Kamenev, Dimitri Gangardt +1
We study the notion of superfluid critical velocity in one spatial dimension. It is shown that for heavy impurities with mass exceeding a critical mass , the disp…

Dynamics and Bloch oscillations of mobile impurities in one-dimensional quantum liquids
Michael Schecter, Dimitri Gangardt, Alex Kamenev
We study dynamics of a mobile impurity moving in a one-dimensional quantum liquid. Such an impurity induces a strong non-linear depletion of the liquid around it. The dispersion re…
