Driven dynamics of an attractive Bose polaron

Saptarshi Majumdar, Aleksandra Petković

We study the out-of-equilibrium dynamics of an impurity driven by a constant external force through a system of homogeneous weakly-interacting bosons in one spatial dimension. The…

Long-lived oscillations of an attractive polaron in a Bose gas

Saptarshi Majumdar, Aleksandra Petković

We study the out-of-equilibrium dynamics of an attractively interacting impurity suddenly immersed with a nonzero initial velocity into a system of one-dimensional weakly interacti…

Bethe-ansatz study of the Bose-Fermi mixture

Soham Chandak, Aleksandra Petković, Zoran Ristivojevic

We consider a one-dimensional mixture of bosons and spinless fermions with contact interactions. In this system, the elementary excitations at low energies are described by four li…

Bloch oscillations of a mobile impurity in a one-dimensional Bose gas

Saptarshi Majumdar, Aleksandra Petković

We study the motion of an impurity under the action of a constant force through a one-dimensional system of weakly-interacting bosons. The interplay of the impurity-boson interacti…

Local spectral density of an interacting one-dimensional Bose gas with an impurity

Aleksandra Petković

A weakly interacting Bose gas with a single static impurity is studied in one dimension. The local spectral density is evaluated and an analytic expression valid for positive stren…

Fluctuation-induced noise in out-of-equilibrium disordered superconducting films

Aleksandra Petković, Valerii M. Vinokur

We study out-of-equilibrium transport in disordered superconductors close to the superconducting transition. We consider a thin film connected by resistive tunnel interfaces to the…
