Quantum impurities: from mobile Josephson junctions to depletons
Michael Schecter, Dimitri M. Gangardt, Alex Kamenev
We overview the main features of mobile impurities moving in one-dimensional superfluid backgrounds by modeling it as a mobile Josephson junction, which leads naturally to the peri…
Comment on "Kinetic theory for a mobile impurity in a degenerate Tonks-Girardeau gas"
Michael Schecter, Alex Kamenev, Dimitri M. Gangardt
In a recent paper, arxiv:1402.6362, Gamayun, Lychkovskiy, and Cheianov studied the dynamics of a mobile impurity embedded into a one-dimensional Tonks-Girardeau gas of strongly int…
Phonon-mediated Casimir interaction between mobile impurities in one-dimensional quantum liquids
Michael Schecter, Alex Kamenev
Virtual phonons of a quantum liquid scatter off impurities and mediate a long-range interaction, analogous to the Casimir effect. In one dimension the effect is universal and the i…
Forming doublons by a quantum quench
Michael Schecter, Alex Kamenev
Repulsive interactions between particles on a lattice may lead to bound states, so called doublons. Such states may be created by dynamically tuning the interaction strength, e.g.…
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…
