Elastic study of electric quadrupolar correlation in the paramagnetic state of a frustrated quantum magnet
Y. Nii, Y. Hirokane, S. Nakamura +4
Electric quadrupolar state in a frustrated quantum magnet has been studied by means of ultrasonic and magnetostriction measurements. A single crys…
Gate-controlled BCS-BEC crossover in a two-dimensional superconductor
Yuji Nakagawa, Yuichi Kasahara, Takuya Nomoto +3
The Bardeen-Cooper-Schrieffer (BCS) condensation and the Bose-Einstein condensation (BEC) are the two extreme limits of the ground state of the paired fermion systems. We report cr…
Dynamical vortex phase diagram of 2D superconductivity in gated MoS2
Yu Saito, Yuki M. Itahashi, Tsutomu Nojima +1
Recent discoveries of two-dimensional (2D) superconductors have uncovered various new aspects of physical properties including vortex matter. In this paper, we report transport pro…
Anomalous Hall effect at the spontaneously electron-doped polar surface of PdCoO2 ultrathin films
T. Harada, K. Sugawara, K. Fujiwara +5
We revealed the electrical transport through surface ferromagnetic states of a nonmagnetic metal PdCoO2. Electronic reconstruction at the Pd-terminated surface of PdCoO2 induces St…
Finite-size effect of critical penetration of Pearl vortices in narrow superconducting flat rings
N. Kokubo, S. Okayasu, T. Nojima
We revisit the critical penetration of Pearl vortices in narrow superconducting flat rings cooled in magnetic fields. Scanning superconducting quantum interference device microscop…
Quantum and classical ratchet motions of vortices in a 2D trigonal superconductor
Yuki M. Itahashi, Yu Saito, Toshiya Ideue +2
Dynamical behavior of vortices plays central roles in the quantum phenomena of two-dimensional (2D) superconductors. Quantum metallic state, for example, showing an anomalous tempe…
