Novel Pauli-paramagnetic quantum phase in a Mott insulator
D. Watanabe, M. Yamashita, S. Tonegawa +9
In Mott insulators, the strong electron-electron Coulomb repulsion prevents metallicity and charge excitations are gapped. In dimensions greater than one, their spins are usually o…
Cyclotron Resonance in the Hidden-Order Phase of URu2Si2
S. Tonegawa, K. Hashimoto, K. Ikada +9
We report the first observation of cyclotron resonance in the hidden-order phase of ultra-clean URuSi crystals, which allows the full determination of angle-dependent elect…
Nematic and meta-nematic transitions in the iron pnictides
S. Kasahara, H. J. Shi, K. Hashimoto +8
Strongly interacting electrons can exhibit novel collective phases, among which the electronic nematic phases are perhaps the most surprising as they spontaneously break rotational…
Microwave Surface-Impedance Measurements of the Magnetic Penetration Depth in Single Crystal Ba1-xKxFe2As2 Superconductors: Evidence for a Disorder-Dependent Superfluid Density
K. Hashimoto, T. Shibauchi, S. Kasahara +10
We report high-sensitivity microwave measurements of the in-plane penetration depth and quasiparticle scattering rate in several single crystals of hole-doped Fe-bas…
