Collective Modes in a Dilute Bose-Fermi Mixture
We here study the collective excitations of a dilute spin-polarized Bose-Fermi mixture at zero temperature, considering in particular the features arising from the interaction between the two species. We show that a propagating zero-sound mode is possible for the fermions even when they do not interact among themselves. PACS numbers: 03.75.Fi, 67.60.-g, 67.55.Jd Recent experimental progress in ...
متن کاملGround state properties of one-dimensional Bose–Fermi mixtures
Bose–Fermi mixtures in one dimension are studied in detail on the basis of an exact solution. Corresponding to three possible choices of the reference state in the quantum inverse scattering method, three sets of Bethe-ansatz equations are derived explicitly. The features of the ground state and low-lying excitations are investigated. The ground state phase diagram caused by the external field ...
متن کامل0 The Ground State Energy of a Dilute Bose Gas ∗
According to a formula that was put forward many decades ago the ground state energy per particle of an interacting, dilute Bose gas at density ρ is 2π~2ρa/m to leading order in ρa3 ≪ 1, where a is the scattering length of the interaction potential and m the particle mass. This result, which is important for the theoretical description of current experiments on Bose-Einstein condensation, has r...

متن کاملDilute Fermi and Bose Gases
We give a unified perspective on the properties of a variety of quantum liquids using the theory of quantum phase transitions. A central role is played by a zero density quantum critical point which is argued to control the properties of the dilute gas. An exact renormalization group analysis of such quantum critical points leads to a computation of the universal properties of the dilute Bose g...
