  • Rydberg atomic gases have proven a fertile playground for exploring exotic phases of condensed matter systems. Here, Li and Das Sarma study Rydberg-dressed atomic fermions in a 3D optical lattice and find a series of mixed topological density wave phases having no analogue in conventional materials.

  • Ultracold atoms in optical lattices exhibit many exotic phenomena. Using interacting spinor Bose gases as a model, Li et al.show how spin-valley degeneracy arising in a multivalley band is broken by quantum fluctuations, resulting in a counterintuitive chiral spin order and a spontaneous spin Hall effect.

  • In spite of recent advances in surgical and medical therapies, the prognosis for patients diagnosed with the high-grade glioma glioblastoma multiforme remains poor. In this Review, Das et al. present evidence that the resistance of these tumors to current therapies is attributable to a small subpopulation of cancer stem cells, and they consider potential new therapeutic strategies that specifically target this cell population.
