Chiral phonons: circularly polarized Raman spectroscopy and $ab initio$ 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…

Chirality-selected crystal growth and spin polarization over centimeters of transition metal disilicide crystals

Yusuke Kousaka, Taisei Sayo, Satoshi Iwasaki +4

We performed a chirality-controlled crystal growth of transition metal disilicide NbSi $_{2}$ and TaSi $_{2}$ by using a laser-diode-heated floating zone (LDFZ) method. The crystal c…

An emergence of chiral helimagnetism or ferromagnetism governed by Cr intercalation in a dichalcogenide CrNb $_{3}$ S $_{6}$

Y. Kousaka, T. Ogura, J. Jiang +4

A synthesis of single crystals of chiral dichalcogenides $T M_{3} X_{6}$ ( $T$ : 3 $d$ transition metal, $M$ : Nb or Ta, $X$ : S or Se) remains an intriguing issue for the investigation o…
