Compressibility of an ultracold Fermi gas with repulsive interactions

To study the effect of repulsive interactions on the equation of state of a Fermi we have measured the isothermal compressibility of the gas as a function of interaction strength [1].  The strength of repulsive interactions for 6Li atoms can be arbitrarily tuned by varying the magnetic field around a broad Feshbach resonance centered at...

Initialization and readout of spin chains for quantum information transport

In these works we studied theoretically and experimentally the many-body dynamics of spin systems and analyzed conditions that would allow for their use in quantum communication.

Formation of Ultracold Fermionic NaLi Feshbach Molecules

We have produced NaLi Feshbach molecules from an ultracold mixture of bosonic 23Na and fermionic 6Li [1]. Precise magnetic field sweeps across a narrow Feshbach resonance convert 5% of free atoms into weakly bound molecules, corresponding to a molecule number of 5 × 104.   NaLi is only the second fermionic heteronuclear molecule produced at ultracold...

Ultracold Fermionic Feshbach Molecules of 23Na40K

We report on the formation of ultracold fermionic Feshbach molecules of $^{23}$Na$^{40}$K, the first fermionic molecule that is chemically stable in its ground state. The lifetime of the nearly degenerate molecular gas exceeds 100 ms in the vicinity of the Feshbach resonance. The measured dependence of the molecular binding energy on the magnetic field demonstrates...

Spin-Injection Spectroscopy of a Spin-Orbit Coupled Fermi Gas

The coupling of the spin of electrons to their motional state lies at the heart of recently discovered topological phases of matter. Here we create and detect spin-orbit coupling in an atomic Fermi gas, a highly controllable form of quantum degenerate matter. We reveal the spin-orbit gap via spin-injection spectroscopy, which characterizes the energy-momentum dispersion...

Quantum nonlinear optics with single photons enabled by strongly interacting atoms

We have realized a quantum nonlinear medium that transmits one, but absorbs two photons. This is accomplished by coupling slowly traveling photons in an atomic gas to highly excited, strongly interacting Rydberg states. This result opens not only possibilities for single-photon sources, but may also enable deterministic quantum gates between photons.
