Description of Interests: 

The Lev Lab is a joint AMO & CM group that explores uncharted regimes of quantum matter by pushing the experimental state-of-the-art. At a billionth of a degree above absolute zero, laser-cooled and trapped gases of neutral atoms are among the coldest objects in the universe. We employ these quantum gases as versatile simulation testbeds and sensors for exploring novel quantum matter and their applications. Our recent projects focus on:

Quantum neural network computing and quantum spin glass using quantum gas multimode cavity QED
    -The first optical lattice with sound has been created, opening up new avenues for quantum simulation
    -We have theoritically descibed how a confocal cavity QED neural network can enhance associative memory recall and storage capacity
    -We realized a versatile set of novel photon-mediated interactions among atoms and dynamical spin-orbit coupling 
    -Read more about the confocal cavity QED neural network and optical lattices with phonon modes in Nature.

1D dipolar quantum gases of the most magnetic atom, dysprosium, to study quantum nonequilibrium physics
    -We discovered novel “quantum many-body scar states” and made a dipolar quantum Newton’s cradle
    -Read more about our quantum many-body scar states in Science and the dipolar quantum Newton’s cradle.

Imaging transport in condensed matter materials with a BEC using our novel Scanning Quantum CRyogentic Atom Microscope (SQCRAMscope)
    -We took the first local images of electron nematic transport in iron-based high-Tc superconductors
    -Read more about the SQCRAMscope and our study of electron nematics.
