THz-induced phonon mode mixing and collective dynamics in a polar nanolattice
Elizabeth Skoropata, Peter M. Derlet, Hiroki Ueda +13
Manipulating phonons through symmetry is a fundamental approach to alter the dynamic responses of materials. Most often new phases are sought through control of the unit-cell (e.g.…
Coherent spin waves in a maximal entropy phase
Arnau Romaguera, Eugenio Paris, Elizabeth Skoropata +24
In solids, disorder is conventionally regarded as detrimental to coherence. It typically localizes and dampens collective excitations, as exemplified by Anderson localization or th…
Observation of mirror-odd and mirror-even spin texture in ultrathin epitaxially strained RuO2 films
Yichen Zhang, Seung Gyo Jeong, Luca Buiarelli +24
Recently, rutile ruthenium dioxide (RuO) has attracted renewed interest due to expectations of prominent altermagnetic spin splitting. However, accumulating experimental eviden…
Common sublattice-pure van Hove singularities in the kagome superconductors VSb ( = K, Rb, Cs)
Yujie Lan, Yuhao Lei, Congcong Le +7
Kagome materials offer a versatile platform for exploring correlated and topological quantum states, where van Hove singularities (VHSs) play a pivotal role in driving electronic i…
Persistence of small polarons into the superconducting phase of BaKBiO
Muntaser Naamneh, Eugenio Paris, Daniel McNally +12
Bipolaronic superconductivity is an exotic pairing mechanism proposed for materials like BaKBiO (BKBO); however, conclusive experimental evidence for a (bi)polaron…
Coexistence of insulator-like paramagnon and metallic spin-orbit exciton modes in SrIrO
Eugenio Paris, Wenliang Zhang, Yi Tseng +13
We probe the spectrum of elementary excitations in SrIrO by using heterostructured [(SrIrO)/(SrTiO)] samples to approach the bulk limit. Our resonant inelastic…
