Interplay between disorder and inversion symmetry: Extreme enhancement of the mobility near the Weyl point in BiTeI
M. Sasaki, Kyoung-Min Kim, A. Ohnishi +5
We show experimental and theoretical evidence that BiTeI hosts a novel disordered metallic state named diffusive helical Fermi liquid (DHFL), characterized by a pair of concentric…

Itinerant-localized dual character of a strongly-correlated superfluid Bose gas in an optical lattice
Y. Ohashi, M. Kitaura, H. Matsumoto
We investigate a strongly-correlated Bose gas in an optical lattice. Extending the standard-basis operator method developed by Haley and Erdos to a boson Hubbard model, we calculat…
