Mottness versus unit-cell doubling as the driver of the insulating state in 1T-TaS2

Autor: C. J. Butler, M. Yoshida, T. Hanaguri, Y. Iwasa

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-6 (2020)

In many strongly correlated systems the coupling of electronic and lattice degrees of freedom leads to ambiguity over the mechanism driving electronic phase transitions. Here the authors show that inter-layer effects play an important role in the cha

Direct observation of imploded core heating via fast electrons with super-penetration scheme

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-10 (2019)

Fast ignition is an interesting scheme for nuclear fusion reaction. Here the authors show electron generation using intense short laser pulses and energy transport by coupling the laser energy to the imploded plasma core as in the ICF conditions.

Superconductivity in a chiral nanotube

Autor: F. Qin, W. Shi, T. Ideue, M. Yoshida, A. Zak, R. Tenne, T. Kikitsu, D. Inoue, D. Hashizume, Y. Iwasa

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-6 (2017)

Chirality affects many properties of materials, but how it affects superconductivity remains unclear. Here, Qinet al. report nonreciprocal supercurrent flows in individual nanotubes of WS2via ionic gating, evidencing chiral superconducting transport.

Upper critical field reaches 90 tesla near the Mott transition in fulleride superconductors

Autor: Y. Kasahara, Y. Takeuchi, R. H. Zadik, Y. Takabayashi, R. H. Colman, R. D. McDonald, M. J. Rosseinsky, K. Prassides, Y. Iwasa

Publikováno v: Nature Communications, Vol 8, Iss 1, Pp 1-6 (2017)

Alkali-doped fullerides are superconductors but the impact of dimensionality and electron correlation remains unclear. Here, Kasaharaet al. report an upper critical field about 90 T, suggesting cooperative interplay between molecular electronic struc
