Many-polaron description of impurities in a Bose-Einstein condensate in the weak coupling regime
W. Casteels, J. Tempere, J. T. Devreese
The weak coupling many-polaron formalism is applied to the case of the polaronic system consisting of impurities in a Bose-Einstein condensate. This allows to investigate the groun…
Vortex core deformation and stepper motor behavior in a superconducting ratchet
J. Van de Vondel, V. N. Gladilin, A. V. Silhanek +4
We investigated experimentally the frequency dependence of a superconducting vortex ratchet effect by means of electrical transport measurements and modeled it theoretically using…
Response of the polaron system consisting of an impurity in a Bose-Einstein condensate to Bragg spectroscopy
W. Casteels, J. Tempere, J. T. Devreese
We expand the existing polaron response theory, expressed within the Mori-Zwanzig projection operator formalism applicable for the transfer of arbitrary energy and zero momentum, t…
