Query: Microscopic theory of the friction force exerted on a quantum impurity
  in one-dimensional quantum liquids   We study the motion of a slow quantum impurity in one-dimensional
environments focusing on systems of strongly interacting bosons and weakly
interacting fermions. While at zero temperature the impurity motion is
frictionless, at low temperatures finite friction appears. The dominant process
is the scattering of the impurity off two fermionic quasiparticles. We evaluate
the friction force and show that, at low temperatures, it scales either as the
fourth or the sixth power of temperature, depending on the system parameters.
This is a result of the scattering of the impurity off two fermionic
quasiparticles that are situated around different Fermi points. It is the
dominant process at low temperatures. We also evaluate the contribution to the
friction force originating from the scattering of the impurity off two
fermionic quasiparticles that are situated around different Fermi points. It
behaves as the tenth power of temperature.
