Three-body recombination at vanishing scattering lengths in an ultracold Bose gas
Zav Shotan, Olga Machtey, Servaas Kokkelmans +1
We report on measurements of three-body recombination rates in an ultracold gas of Li atoms in the extremely nonuniversal regime where the two-body scattering length vanishes.…
Association of Efimov trimers from a three-atom continuum
Olga Machtey, Zav Shotan, Noam Gross +1
We develop an experimental technique for rf-association of Efimov trimers from three-atoms continuum. We apply it to probe the lowest accessible Efimov energy level in bosonic lith…
Universal Dimer in a Collisionally Opaque Medium: Experimental Observables and Efimov Resonances
Olga Machtey, David A. Kessler, Lev Khaykovich
A universal dimer is subject to secondary collisions with atoms when formed in a cloud of ultracold atoms via three-body recombination. We show that in a collisionally opaque mediu…
Study of Efimov physics in two nuclear-spin sublevels of 7Li
Noam Gross, Zav Shotan, Olga Machtey +2
Efimov physics in two nuclear-spin sublevels of bosonic lithium is studied and it is shown that the positions and widths of recombination minima and Efimov resonances are identical…
Metastable nonconfining states in SU(3) lattice gauge theory with sextet fermions
Olga Machtey, Benjamin Svetitsky
We study the SU(3) lattice gauge theory, with two flavors of sextet Wilson-clover fermions, near its finite-temperature phase transition. We find metastable states that have Wilson…
