Magnetic field control over the axialness of Higgs modes in charge-density wave compounds
Dirk Wulferding, Jongho Park, Takami Tohyama +2
Understanding how symmetry-breaking processes generate order out of disorder is among the most fundamental problems of nature. The scalar Higgs mode - a massive (quasi-) particle -…
Linear scaling relationship of Néel temperature and dominant magnons in pyrochlore ruthenates
Jae Hyuck Lee, Dirk Wulferding, Junkyoung Kim +3
We present a systematic Raman spectroscopy study on a series of pyrochlore ruthenates, a system which is not yet clearly settled on its magnetic origin and structure. Apart from th…
Tetrahedral triple-Q magnetic ordering and large spontaneous Hall conductivity in the metallic triangular antiferromagnet Co1/3TaS2
Pyeongjae Park, Woonghee Cho, Chaebin Kim +14
The triangular lattice antiferromagnet (TLAF) has been the standard paradigm of frustrated magnetism for several decades. The most common magnetic ordering in insulating TLAFs is t…
Significant thermal Hall effect in the 3 cobalt Kitaev system
Heejun Yang, Chaebin Kim, Ysun Choi +9
Kitaev physics has recently attracted attention in condensed matter for its anticipated novel quantum spin liquid state. The thermal transport measurement is crucial for probing th…
Collective magnetic Higgs excitation in a pyrochlore ruthenate
Dirk Wulferding, Junkyeong Kim, Mi Kyung Kim +13
The emergence of scalar Higgs-type amplitude modes in systems where symmetry is spontaneously broken has been a highly successful, paradigmatic description of phase transitions, wi…
Field-tunable toroidal moment and anomalous Hall effect in noncollinear antiferromagnetic Weyl semimetal Co1/3TaS2
Pyeongjae Park, Yoon-Gu Kang, Junghyun Kim +4
Combining magnetism with band topology provides various novel phases that are otherwise impossible. Among several cases, noncollinear metallic antiferromagnets can reveal particula…
