Anomalous Hall effect with plateaus observed in a magnetic Weyl semimetal NdAlGe at low temperatures
Naoki Kikugawa, Shinya Uji, Taichi Terashima
In the Al(Si,Ge) (: lanthanides) family, both spatial inversion and time-reversal symmetries are broken. This may offer opportunities to study Weyl-fermion physics in nontriv…
Fermi surface and light quasi particles in hourglass nodal chain metal \b{eta}-ReO2
Daigorou Hirai, Takahito Anbai, Takako Konoike +8
Quantum oscillations in magnetic torque and electrical resistivity were measured to investigate the electronic structure of \b{eta}-ReO2, a candidate hourglass nodal chain metal (D…
CeFeAl: a Correlated Metal with a Fermi Surface Exhibiting Nonmetallic Conduction
Taichi Terashima, Hishiro T. Hirose, Naoki Kikugawa +3
Metals can be defined as materials with a Fermi surface or as materials exhibiting metallic conduction (i.e., ). Usually, these definitions both hold…
Topological frequency shift of quantum oscillation in CaFeAsF
Taichi Terashima, Shinya Uji, Teng Wang +1
Guo, Alexandradinata, \textit{et al.} have recently proposed that quantum-oscillation frequencies from Dirac/Weyl fermions exhibit a negative shift proportional to because of…
Ferromagnetism out of charge fluctuation of strongly correlated electrons in -(BEDT-TTF)Hg(SCN)Br
Minoru Yamashita, Shiori Sugiura, Akira Ueda +10
We perform magnetic susceptibility and magnetic torque measurements on the organic -(BEDT-TTF)Hg(SCN)Br, which is recently suggested to host an exotic quantum dipole-liq…
Real spin and pseudospin topologies in the noncentrosymmetric topological nodal-line semimetal CaAgAs
Hishiro T. Hirose, Taichi Terashima, Taichi Wada +4
We present the topology of spin-split Fermi surface of CaAgAs as determined by de Haas-van Alphen (dHvA) effect measurements combined with ab initio calculations. We have determine…
The Fermi surface of PtCoO2 from quantum oscillations and electronic structure calculations
F. Arnold, M. Naumann, H. Rosner +9
The delafossite series of layered oxides include some of the highest conductivity metals ever discovered. Of these, PtCoO2, with a room temperature resistivity of 1.8 microOhmcm fo…
Continuous Tensor Network States for Quantum Fields
Antoine Tilloy, J. Ignacio Cirac
We introduce a new class of states for bosonic quantum fields which extend tensor network states to the continuum and generalize continuous matrix product states (cMPS) to spatial…
Split Fermi Surfaces of the Spin-Orbit-Coupled Metal Cd2Re2O7 Probed by de Haas-van Alphen Effect
Yasuhito Matsubayashi, Kaori Sugii, Hishiro T. Hirose +5
The superconducting pyrochlore oxide Cd2Re2O7 shows a structural transition with inversion symmetry breaking (ISB) at Ts1 = 200 K. A recent theory [L. Fu, Phys. Rev. Lett. 115, 026…

Haruyoshi Aoki, Noriaki Kimura, Taichi Terashima
This article describes the Fermi surface properties of CeRuSi and its alloy systems CeRu(SiGe) and CeLaRuSi studied by the de Haas -…
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…
Quasi-Two-Dimensional Fermi Surfaces and Coherent Interlayer Transport in KFeAs
M. Kimata, T. Terashima, N. Kurita +15
We report the results of the angular-dependent magnetoresistance oscillations (AMROs), which can determine the shape of bulk Fermi surfaces in quasi-two-dimensional (Q2D) systems,…
