    Research Statement

     

    Randall Hulet investigates atoms at temperatures as low as a few nano-Kelvin. At these low temperatures the quantum mechanical wavelengths of the atoms can be as large as 1 micron, greatly altering normal atomic behavior. Hulet and his group have used laser cooling and atom trapping techniques to explore this exotic regime of matter, investigating ultracold atom collisions and quantum statistical effects, such as Bose-Einstein condensation. Collisions between ultracold atoms can reveal the subtle nature of their mutual interaction. Hulet and group use laser spectroscopy to probe these interactions. By this technique they discovered that two 7Li atoms weakly attract each other at very low temperature. Theorists believed that this fact would prevent lithium from undergoing a Bose-Einstein condensation, the paradigm of all quantum statistical phase transitions. In 1995, however, Hulet and his group succeeded in coaxing a gas of magnetically confined 7Li atoms to Bose condense. Subsequent investigation of this novel system has lead to the direct observation of condensate growth and collapse.


    Hulet and group later produced the first quantum degenerate Bose/Fermi (7Li / 6Li) mixture of ultracold gases. The size of the fermion atom cloud was stabilized by Fermi pressure, in analogy to a white dwarf or neutron star. More recent investigations have focused on superfluidity of atomic Fermi gases, using Cooper paired 6Li atoms. These pairs are a close analogy to those resulting in superconductivity of some solids. This goal of this work is to better understand the nature of high-temperature superconductors and other strongly correlated materials.


     

     
    Research Interests 30-JAN-2019
     

    The focus of my research program is the study of quantum gases of ultracold atoms. My current activities employ the isotopes of lithium, the fermion 6Li and the boson 7Li, to model complex condensed matter phenomena and materials. Ultracold atomic gases are highly controllable and well-characterized making them ideal systems to test fundamental models of important materials, such as high-temperature superconductors.


    In one experiment, Bose-Einstein condensates are used to create bright matter-wave solitons, while in another, the fermion counterparts are used to investigate fermionic superfluidity in the strongly-interacting regime.  The role of dimensionality is explored using optical lattices, while we also study the effect of spin-polarization on the superfluid transition.


    The pairing of fermions to form composite bosons underlies two of the most remarkable phenomena in physics: superconductivity and superfluidity. Below a certain critical temperature the electrons in a superconductor pair up, one with its spin up and the other with its spin down, forming the supercurrent-carrying Cooper. Although the conventional BCS theory of superconductivity requires an equal number of spin-up and spin-down particles, physicists have long speculated on what happens if this condition is not met. At Rice, we have shown that a mixture of lithium-6 atoms, the fermions, can pair up even when there are unequal numbers of spin-up and spin-down atoms. With equal numbers and at low enough temperature, about 30 nK, the lithium-6 atoms phase separate into a superfluid core surrounded by a normal shell of the majority spin-up atoms. The interface between the superfluid and normal phases is sharp, indicative of a first order phase boundary, and surface tension at this boundary causes a deformation of the superfluid. The confinement potential creates an elongated cigar-like distribution that we observe to become progressively less elongated with increasing number mismatch, as the superfluid is driven to minimize the ratio of the surface area to volume. Phase separation was just one of the scenarios predicted by theorists prior to our experiment. More exotic phases, including one with pairs having non-zero center of mass momentum, have also been predicted. Our current efforts are focused on finding this so-called FFLO phase (after its originators), especially in one dimension where this new phase of matter is predicted to be especially robust. Research with strongly interacting Fermi gases bear on diverse phenomena ranging from high-temperature superconductivity to the dense quark matter predicted to reside in the cores of neutron stars.


    In our previous work we have obtained evidence for the FFLO phase in one-dimension.  However, the smoking gun for FFLO pairing are pairs with non-zero center of mass momentum or periodic domain boundaries that contain the excess unpaired atoms.  Theory points to the crossover between 1D and 3D as perhaps the most fruitful region of dimensional space to search for the signature of the FFLO state.
