From Planar Solitons to Vortex Rings and Lines: Cascade of Solitonic Excitations in a Superfluid Fermi Gas
Mark J. H. Ku, Biswaroop Mukherjee, Tarik Yefsah +1
We follow the time evolution of a superfluid Fermi gas of resonantly interacting Li atoms after a phase imprint. Via tomographic imaging, we observe the formation of a planar d…
Heavy Solitons in a Fermionic Superfluid
Tarik Yefsah, Ariel T. Sommer, Mark J. H. Ku +4
Topological excitations are found throughout nature, in proteins and DNA, as dislocations in crystals, as vortices and solitons in superfluids and superconductors, and generally in…
Collective Modes in a Unitary Fermi Gas across the Superfluid Phase Transition
Meng Khoon Tey, Leonid A. Sidorenkov, Edmundo R. Sánchez Guajardo +6
We provide a joint theoretical and experimental investigation of the temperature dependence of the collective oscillations of first sound nature exhibited by a highly elongated har…
Revealing the Superfluid Lambda Transition in the Universal Thermodynamics of a Unitary Fermi Gas
Mark J. H. Ku, Ariel T. Sommer, Lawrence W. Cheuk +1
We have observed the superfluid phase transition in a strongly interacting Fermi gas via high-precision measurements of the local compressibility, density and pressure down to near…
Feynman diagrams versus Fermi-gas Feynman emulator
K. Van Houcke, F. Werner, E. Kozik +7
Precise understanding of strongly interacting fermions, from electrons in modern materials to nuclear matter, presents a major goal in modern physics. However, the theoretical desc…
Spin Transport in Polaronic and Superfluid Fermi Gases
Ariel Sommer, Mark Ku, Martin W. Zwierlein
We present measurements of spin transport in ultracold gases of fermionic lithium-6 in a mixture of two spin states at a Feshbach resonance. In particular, we study the spin dipole…
