Direct observation of lattice symmetry breaking at the hidden-order transition in URu2Si2
S. Tonegawa, S. Kasahara, T. Fukuda +12
Since the 1985 discovery of the phase transition at K in the heavy-fermion metal URuSi, neither symmetry change in the crystal structure nor magnetic orde…
Cyclotron resonance study of quasiparticle mass and scattering rate in the hidden-order and superconducting phases of URu2Si2
S. Tonegawa, K. Hashimoto, K. Ikada +10
The observation of cyclotron resonance in ultra-clean crystals of URu2Si2 [S. Tonegawa et al., PRL 109, 036401 (2012)] provides another route besides quantum oscillations to the de…
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…
Evidence for superconducting gap nodes in the zone-centered hole bands of KFe2As2 from magnetic penetration-depth measurements
K. Hashimoto, A. Serafin, S. Tonegawa +13
Among the iron-based pnictide superconductors the material KFeAs is unusual in that its Fermi surface does not consist of quasi-nested electron and hole pockets. Here we re…
