Collective Modes of an Ultracold 6Li-40K Mixture in an Optical Lattice

Figure 1

The phase diagrams of a mixture in a square lattice [10]. The interaction strength is . The polarization is defined as , where the total filling is atoms/lattice site. Colors: Sarma states = blue (black), FF = red (dark grey), and normal gas = white.
