“…11 to the resonance positions to obtain the energy shifts ∆U eg ± = U eg ± − U gg . From our measurement we find ∆U eg + /h = 3.53(4) kHz and ∆U eg − /h = 2.32(3) kHz corresponding to s-wave scattering lengths of a eg + = 203(5) a 0 and a eg − = 308(6) a 0 , respectively, in fair agreement with previously measured values [63,80]. We explicitly measure the Rabi frequencies of the two particle transitions at different magnetic fields, shown in Fig.…”

“…The elastic interactions are similar, which we attribute to the high degree of symmetry of the underlying molecular potentials. Together with the data obtained in [17,18,70,71,[80][81][82][83] our measurements could contribute to a more precise understanding of the molecular potential of excited-ground state dimers in Yb. Additionally, the inelastic interactions differ by more than two orders of magnitude, which could prove interesting as a test for future theoretical models.…”

“…We identify the two large peaks as being caused by sites singly occupied with either 171 Yb ↑ or 171 Yb ↓ particles. They are separated by the Zeeman energy ∆E Z = −399.0(1) Hz/G • ∆m F B [80]. In addition, we observe two interisotope interorbital peaks shifted by ∆ 171 173 U eg relative to the 171 Yb ↑ and 171 Yb ↓ states, respectively.…”

“…These peaks can be understood as follows (see also Refs. [63,80]). At vanishing magnetic field the anti-symmetric wave function required for two indistinguishable fermionic particles can be realized in two ways: either by a spin singlet with a symmetric orbital wave function denoted by |eg + = 1/ √ 2(|eg + |ge ) ⊗ |s or a spin triplet with an anti-symmetric orbital wave function denoted by |eg − = 1/ √ 2(|eg − |ge ) ⊗ |t .…”

We characterize inter-and intraisotope interorbital interactions between atoms in the 1 S0 ground state and the 3 P0 metastable state in interacting Fermi-Fermi mixtures of 171 Yb and 173 Yb. We perform high-precision clock spectroscopy to measure interaction-induced energy shifts in a deep 3D optical lattice and determine the corresponding scattering lengths. We find the elastic interaction of the interisotope mixtures 173 Ybe-171 Ybg and 173 Ybg-171 Ybe to be weakly attractive and very similar, while the corresponding two-body loss coefficients differ by more than two orders of magnitude. By comparing different spin mixtures we experimentally demonstrate the SU(2)⊗ SU( 6) symmetry of all elastic and inelastic interactions. Furthermore, we measure the spin-exchange interaction in 171 Yb and confirm its previously observed antiferromagnetic nature.

“…The result of the numerical calculation of the phase shift difference, associated with the transmittance, is consistent with the faster transport dynamics observed in a magnetic field of 135 Gauss than in 45 Gauss (see Suppelmentary Information). We repeat a similar transport measurement using 171 Yb which does not show an orbital Feshbach resonance in the magnetic field range of the present experiment [29]. The result shows much slow decoherence consistent with the expectation.…”

Quantum transport is ubiquitous in physics. So far, quantum transport between terminals has been extensively studied in solid state systems from the fundamental point of views such as the quantized conductance to the applications to quantum devices. Recent works have demonstrated a cold-atom analog of a mesoscopic conductor by engineering a narrow conducting channel with optical potentials, which opens the door for a wealth of research of atomtronics emulating mesoscopic electronic devices and beyond. Here we realize an alternative scheme of the quantum transport experiment with ytterbium atoms in a two-orbital optical lattice system. Our system consists of a multi-component Fermi gas and a localized impurity, where the current can be created in the spin space by introducing the spin-dependent interaction with the impurity. We demonstrate a rich variety of localized-impurity-induced quantum transports, which paves the way for atomtronics exploiting spin degrees of freedom.

Observation of spin-exchange dynamics between itinerant and localized Yb171 atoms

We report on the observation of the spin-exchange dynamics of 171 Yb atoms in the ground state 1 S 0 and in the metastable state 3 P 0 . We implement the mixed-dimensional two-orbital system using near-resonant and magic-wavelength optical lattices, where the 1 S 0 and 3 P 0 atoms are itinerant in a one-dimensional tube and localized in three dimensions, respectively. By exploiting an optical Stern-Gerlach method, we observe the spin depolarization of the 1 S 0 atoms induced by the spin-exchange interaction with the 3 P 0 atom. Our work could pave the way to the quantum simulation of the Kondo effect.
