Chiral phonons: circularly polarized Raman spectroscopy and calculations in a chiral crystal tellurium
Kyosuke Ishito, Huiling Mao, Kaya Kobayashi +5
Recently, phonons with chirality (chiral phonons) have attracted significant attention. Chiral phonons exhibit angular and pseudo-angular momenta. In circularly polarized Raman spe…
Full superconducting gap in the candidate topological superconductor InPbTe for x = 0.2
M. P. Smylie, Kaya Kobayashi, J. Z. Dans +4
High-pressure synthesis techniques have allowed for the growth of samples on the indium-rich side of (Pb,In)Te, which have increased superconducting transition temperatures compare…
Chirality-Induced Electrical Generation of Magnetism in Nonmagnetic Elemental Tellurium
Tetsuya Furukawa, Yuta Watanabe, Naoki Ogasawara +2
Chiral matter has a structure that lacks inversion, mirror, and rotoreflection symmetry; thus, a given chiral material has either a right- or left-handed structure. In chiral matte…
Magneto-transport properties of tellurium under extreme conditions
Kazuto Akiba, Kaya Kobayashi, Tatsuo C. Kobayashi +5
This study investigates the transport properties of a chiral elemental semiconductor tellurium (Te) under magnetic fields and pressure. Application of hydrostatic pressure reduces…
Optical signatures of phase transitions and structural modulation in elemental tellurium under pressure
Diego Rodriguez, Alexander A. Tsirlin, Tobias Biesner +5
A room-temperature infrared spectroscopy study of elemental tellurium at pressures up to 8.44 GPa in the energy range 0.015-2 eV is reported. Optical signatures of the high-pressur…
Two linear regimes in optical conductivity of a Type-I Weyl semimetal: the case of elemental tellurium
Diego Rodriguez, Alexander A. Tsirlin, Tobias Biesner +5
Employing high-pressure infrared spectroscopy we unveil the Weyl semimetal phase of elemental Te and its topological properties. The linear frequency dependence of the optical cond…
