“…This counterintuitive behavior leads to a rich phase diagram that contains, for example, self-bound quantum droplets [5,6] and supersolid states [7][8][9][10]. While many aspects like rotonic excitation spectra [11][12][13][14][15][16][17][18][19], anisotropic superfluidity [20,21], droplet formation [1,6,22], crystallization in 1D [23][24][25][26][27][28], 2D [3,18,19,29,30] and into more exotic patterns [31,32], have been extensively discussed for weakly-dipolar magnetic atoms, systematic studies for molecules, with their much larger and tunable electric dipole moments, have so far remained scarce. Here, we show that Bose-Einstein condensates of ground-state molecules are ideal candidates to further explore the rich phase diagrams of dipolar Bose gases in experiments [33].…”
