Disturbing the Fermi Sea with Rydberg States May 17, 2021• Physics 14, 74 A method that enables long-range interactions between fermions on a lattice allows atomic quantum simulations of exotic quantum many-body phenomena. 6 Li atoms (red) are prevented by Pauli exclusion from occupying the same ground state, they each occupy a different low-energy state, forming a Fermi sea (green). Exciting the atoms to Rydberg states (inset) allows them to interact, driving fluctuations in the Fermi sea and generating exotic quantum phenomena.When fermionic 6 Li atoms (red) are prevented by Pauli exclusion from occupying the same ground state, they each occupy a different low-energy state, forming a Fermi sea (green).
