Quantum Engineering of Strongly Correlated Matter with Ultracold Fermi Gases
Abstract
This is the final report on the Young Investigator Program (YIP), which is currently being continued as a Presidential Early Career Award for Science and Education (PECASE). In this program, we aim at realizing model systems of strongly correlated, disordered electrons using ultracold fermionic atoms stored in an optical "crystal". The general theme is to study high-temperature superfluids, Fermi liquids ("metals") and insulators in the presence of disordered impurities whose influence on the fermions can be controlled. In the one-year funding period of the YIP, we have completed and exceeded the goals set for year 1 of the program: We studied spin transport in strongly interacting Fermi gases by watching the motion of impurities, so-called Fermi Polarons, through a Fermi sea of atoms; we have simultaneously immersed two different kinds of fermionic impurities of differing mass in a Bose-Einstein condensate, that provides a phonon background analogous to that in a crystal. Furthermore, we have performed a theoretical study on localized magnetic impurities in a superfluid of paired ultracold fermions.
