Calculations of the Russian researcher from Moscow Institute of Physics and Technology show that fermionic matter can exist in previously unknown type of the one-dimension liquid.

      According to the scientist, one-dimension liquid is not that type of matter we can observe with a naked eye. The term "liquid" here means models, describing multi-particle systems with interactions between particles. Such models can describe well-known objects like electrons in conductors, as well as unusual ones like nanotubes and graphene sheets.

      To date two models of fermionic matter exist - fermi-liquid, which works in two- and three-dimensional space, and Tomonaga-Luttinger liquid for one-dimension space. New state of fermionic matter resembles both of them, but is different nevertheless.

      Fermionic matter consists of fermions, which are particles with half-integral spin.
