Hybrid Quantum System of Fermionic Neutral Atoms in a Tunable Optical Lattice

Multivalent optical cycling centers: towards control of polyatomics with multi-electron degrees of freedom

“…4 Tunable spin couplings within multivalent molecules could also have utility in many-body quantum simulation. This can be illustrated via analogy with the structure of AEL atoms, which have been leveraged to simulate high-dimensional SU(N) Hamiltonians through nuclear spin-independence [72][73][74][75][76][77] as well as study multi-orbital physics via orbital Feshbach resonances 207,208 and spin-orbital effects. [208][209][210][211][212][213] Incorporating tunable multi-electron degrees of freedom with the unique benefits of polyatomic molecular structure 8,102 (e.g.…”

“…Individual atoms that possess two (or more) valence cycling electrons, such as AEL atoms, give rise to electronic states with metastable lifetimes, 54,55 ultranarrow optical transitions, [56][57][58] perturbation-free ''magic'' trapping conditions, [59][60][61] efficient autoionization pathways, [62][63][64] and fully tunable couplings to internal spins. 65 Leveraging these features in multi-electron atoms has been a principal factor enabling record-setting optical lattice [66][67][68][69] and tweezer clocks, 70,71 analog many-body simulators of highdimensional and multiorbital Hamiltonians, [72][73][74][75][76][77] advanced atom interferometers, 78 high-fidelity entangling gates, 64,79,80 and telecom-compatible quantum transducers and memories. [81][82][83][84][85] In this paper, we assess the feasibility of using generalized, ''multivalent'' electronic structure for photon cycling and optical control of polyatomic molecules.…”

Universal Kardar-Parisi-Zhang dynamics in integrable quantum systems

“…Experimental proposal.-Recent advances in the control and manipulation of alkaline-earth atoms in optical lattices have opened the door to studying SU(N )symmetric spin models [62][63][64][65][66][67][68][69][70][71]. In particular, at unitfilling in the Mott insulating phase, the lack of hyperfine coupling in the ns 2 1 S 0 electronic ground state naturally leads to SU(N )-symmetric spin-exchange interactions [70,[72][73][74]:…”

Recent progresses of ultracold two-electron atoms

“…Finally, we remark that nearest-neighbor antiferromagnetic spin correlations are measured in a dimerized lattice for tunable SU(N) fermions. Ozawa et al found that the antiferromagnetic correlation is enhanced for larger N due to a Pomeranchuk cooling effect [97].…”
