Partial molecular orbitals in face-sharing 3 $d$ manganese trimer: Comparative studies on Ba $_{4}$ TaMn $_{3}$ O $_{12}$ and Ba $_{4}$ NbMn $_{3}$ O $_{12}$

Anzar Ali, Heung-Sik Kim, Poonam Yadav +3

We present a molecular orbital candidate Ba $_{4}$ TaMn $_{3}$ O $_{12}$ with a face-sharing octahedra trimer, by comparing it with a related compound Ba $_{4}$ NbMn $_{3}$ O $_{12}$ . The sy…

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…
