Local manipulation of quantum magnetism in one-dimensional ultracold Fermi gases across narrow resonances
Local manipulation of quantum magnetism in one-dimensional ultracold Fermi gases across narrow resonances
Effective range is a quantity to characterize the energy dependence in two-body scattering strength, and is widely used in cold atomic systems especially across narrow resonances. Here we show that the effective range can significantly modify the magnetic property of one-dimensional (1D) spin-$1/2$ fermions in the strongly repulsive regime. In …
