Thermal Hall effect in a phonon-glass BaCuSbO
Kaori Sugii, Masaaki Shimozawa, Daiki Watanabe +6
A distinct thermal Hall signal is observed in a quantum spin liquid candidate BaCuSbO. The transverse thermal conduction shows a power-law temperature dependence below…
Emergence of nontrivial magnetic excitations in a spin liquid state of kagome volborthite
Daiki Watanabe, Kaori Sugii, Masaaki Shimozawa +7
When quantum fluctuations destroy underlying long-range ordered states, novel quantum states emerge. Spin-liquid (SL) states of frustrated quantum antiferromagnets, in which highly…
CeCu_2Ge_2: Challenging our Understanding of Quantum Criticality
B. Zeng, Q. R. Zhang, D. Rhodes +6
Here, we unveil evidence for a quantum phase-transition in CeCu_2Ge_2 which displays both an incommensurate spin-density wave (SDW) ground-state, and a strong renormalization of th…
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…
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…
