  • Interaction-Induced Metallicity in a Two-Dimensional Disordered Non-Fermi Liquid PHYSICAL REVIEW LETTERS Nosov, P. A., Burmistrov, I. S., Raghu, S. 2020; 125 (25): 256604


    The interplay of interactions and disorder in two-dimensional (2D) electron systems has actively been studied for decades. The paradigmatic approach involves starting with a clean Fermi liquid and perturbing the system with both disorder and interactions. Instead, we start with a clean non-Fermi liquid near a 2D ferromagnetic quantum critical point and consider the effects of disorder. In contrast with the disordered Fermi liquid, we find that our model does not suffer from runaway flows to strong coupling and the system has a marginally stable fixed point with perfect conduction.

  • Anomalous Temperature Behavior of the Chiral Spin Helix in CrNb3S6 Thin Lamellae PHYSICAL REVIEW LETTERS Togawa, Y., Kishine, J., Nosov, P. A., Koyama, T., Paterson, G. W., McVitie, S., Kousaka, Y., Akimitsu, J., Ogata, M., Ovchinnikov, A. S. 2019; 122 (1): 017204


    Using Lorentz transmission electron microscopy and small-angle electron scattering techniques, we investigate the temperature-dependent evolution of a magnetic stripe pattern period in thin-film lamellae of the prototype monoaxial chiral helimagnet CrNb_{3}S_{6}. The sinusoidal stripe pattern appears due to formation of a chiral helimagnetic order (CHM) in this material. We found that as the temperature increases, the CHM period is initially independent of temperature and then starts to shrink above the temperature of about 90 K, which is far below the magnetic phase transition temperature for the bulk material T_{c} (123 K). The stripe order disappears at around 140 K, far above T_{c}. We argue that this cascade of transitions reflects a three-stage hierarchical behavior of melting in two dimensions.
