Superfluid Fermi liquid in a unitary regime

Abstract

A short popular review of theoretical and experimental results about properties of ultracold Fermi gases in vicinity of the Feshbach resonance is presented. The paper is based on the authors talk on the meeting of the Physical Department of the Russian Academy of Sciences dedicated to 100th anniversary of the birth of L. D. Landau (Moscow, January 22, 2008). A version of this article has been published in Physics - Uspekhi v. 51 p. 603 (2008).

8 pages, 6 figures. The paper is based on the authors talk on the meeting of the Physical Department of the Russian Academy of Sciences dedicated to the 100th anniversary of the birth of L. D. Landau (Moscow, January 22, 2008)
