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…
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…
phonon anomaly driven by Fermi surface instability at intermediate temperature in YBaCuO
Dongjin Oh, Dongjoon Song, Younsik Kim +5
We performed temperature- and doping-dependent high-resolution Raman spectroscopy experiments on YBaCuO to study phonons. The temperature dependence…
Experimental observation of hidden Berry curvature in inversion-symmetric bulk 2H-WSe2
Soohyun Cho, Jin-Hong Park, Jisook Hong +11
We investigate the hidden Berry curvature in bulk 2H-WSe2 by utilizing the surface sensitivity of angle resolved photoemission (ARPES). The symmetry in the electronic structure of…
Giant Rashba-type spin splitting through spin-dependent interatomic-hopping
Jisook Hong, Jun-Won Rhim, Inkyung Song +3
We have performed density functional theory calculation and tight binging analysis in order to investigate the mechanism for the giant Rashba-type spin splitting (RSS) observed in…
Experimental determination of the massive Dirac fermion model parameters for MoS, MoSe, WS, and WSe
Beom Seo Kim, Jun-Won Rhim, Beomyoung Kim +2
Monolayer MX (M = Mo, W; X = S, Se) has drawn much attention recently for its possible application possibilities for optoelectronics, spintronics, and valleytronics. Its exotic…
