Abstract

MASS IMBALANCED MIXTURES OF ULTRACOLD FERMIONIC ATOMS OPEN UNPRECEDENTED POSSIBILITIES TO EXTEND THE RESEARCH FIELD OF ULTRACOLD FERMI GASES.
MICROLIM WILL EXPLOIT A NOVEL MIXTURE OF ULTRACOLD FERMIONIC CHROMIUM AND LITHIUM ATOMS WITH TUNABLE INTERACTIONS TO UNVEIL AND EXPLORE A VARIETY OF NOVEL QUANTUM REGIMES. THE PECULIAR CR-LI MASS RATIO WILL UNIQUELY ENABLE THE EMERGENCE OF NOVEL, COLLISIONALLY STABLE, CLUSTER STATES, BOTH WITH FERMIONIC AND BOSONIC CHARACTER, FEATURING P-WAVE ORBITAL SYMMETRY. OUR MIXTURE WILL ALSO PAVE THE WAY TO A WEALTH OF MANY-BODY SURVEYS: FROM THE STUDY OF THE SO-CALLED BCS-BEC CROSSOVER WITH MASS ASYMMETRY, EXPECTED TO EXHIBIT VERY EXOTIC SUPERFLUID REGIMES, TO A VARIETY OF QUANTUM SYSTEMS CHARACTERIZED BY STRONG P-WAVE FEW-BODY CORRELATIONS. IN PARTICULAR, THE CR-LI SYSTEM IS VERY PROMISING TO DISCLOSE, FOR THE FIRST TIME, P-WAVE SUPERFLUIDITY IN A QUANTUM GAS. FINALLY, THE MAGNETIC NATURE OF CHROMIUM, COMBINED WITH A RICH SPECTRUM OF CR-LI FESHBACH RESONANCES, WILL ALLOW TO REALIZE GROUND STATE MOLECULES FEATURING BOTH MAGNETIC AND ELECTRIC DIPOLE MOMENTS. THIS MAKES CRLI MOLECULES EXCELLENT CANDIDATES FOR STUDIES OF LATTICE-SPIN MODELS AND PRECISION
