Dynamic structure factor and drag force in a one-dimensional strongly interacting Bose gas at finite temperature

Guillaume Lang, F. W. J. Hekking, Anna Minguzzi

We study the effect of thermal and quantum fluctuations on the dynamical response of a one-dimensional, strongly interacting Bose gas in a tight atomic waveguide. We combine the Luttinger liquid theory at arbitrary interactions and the exact Bose-Fermi mapping in the Tonks-Girardeau impenetrable-boson limit to obtain the dynamic structure factor of the strongly interacting fluid at finite temperature. Then we determine the drag force felt by a potential barrier moving along the fluid in the experimentally realistic situation of finite barrier width and temperature.

A note on the generalization of Bijl-Feynman spectrum to multi-component systems with an application to double-layer charged Bose gas

B. Tanatar

We consider the generalization of Bijl-Feynman excitation energy formula to multi-component Bose fluids. Identification of these excitation energies with those obtained from the poles of the density-density response function simplifies the calculation of static structure factors Sij(q) . This in turn helps simplify the self-consistent calculations that go beyond the usual random-phase approximation. We illustrate our approach by evaluating the structure factors and local-field corrections in a double-layer charged Bose gas. © Tübi̇tak.
