Collective Magnetic Excitations in a Photo-excited Electron-doped Cuprate Superconductor
Daniel Jost, Jiarui Li, Jordyn Hales +21
Elucidating the microscopic behavior of cuprates under ultrafast photoexcitation offers critical insights into their highly correlated out-of-equilibrium states. Although quasipart…
Ultrafast decoupling of polarization and strain in ferroelectric BaTiO
Le Phuong Hoang, David Pesquera, Gerard N. Hinsley +20
A fundamental understanding of the interplay between lattice structure, polarization and electrons is pivotal to the optical control of ferroelectrics. The interaction between ligh…
Spin-orbital excitations encoding the magnetic phase transition in the van der Waals antiferromagnet FePS
Yuan Wei, Yi Tseng, Hebatalla Elnaggar +13
In the rich phases of van der Waals (vdW) materials featuring intertwined electronic order and collective phenomena, characterizing elementary dynamics that entail the low-energy H…
Unraveling the Mn -edge RIXS spectrum of lightly manganese doped SrRuO
Wei-Yang Chen, Shih-Wen Huang, Yi Tseng +10
Resonant inelastic x-ray scattering (RIXS) experiment was performed at the Mn edge. A 10 Mn-doped SrRuO compound, where the Mn ions are in the 3…
Emergence of interfacial magnetism in strongly-correlated nickelate-titanate superlattices
Teguh Citra Asmara, Robert J. Green, Andreas Suter +21
Strongly-correlated transition-metal oxides are widely known for their various exotic phenomena. This is exemplified by rare-earth nickelates such as LaNiO, which possess int…
Nematic charge-density-wave correlations in FeSeS
Ruixian Liu, Wenliang Zhang, Yuan Wei +5
The occurrence of charge-density-wave (CDW) order is a common thread in the phase diagram of cuprate high-transition-temperature () superconductors. In iron-based superconduct…
Nematic spin correlations pervading the phase diagram of FeSeS
Ruixian Liu, Wenliang Zhang, Yuan Wei +8
We use resonant inelastic X-ray scattering (RIXS) at the Fe-L edge to study the spin excitations of uniaxial-strained and unstrained FeSeS () sam…
Spin waves and orbital contribution to ferromagnetism in a topological metal
Wenliang Zhang, Teguh Citra Asmara, Yi Tseng +11
Special arrangements of atoms with more than one atom per unit cell, including honeycomb or kagome (woven bamboo mat) lattices, can host propagating excitations with non-trivial to…
Unravelling the Nature of Spin Excitations Disentangled from Charge Contributions in a Doped Cuprate Superconductor
Wenliang Zhang, Cliò Efthimia Agrapidis, Yi Tseng +7
The nature of the spin excitations in superconducting cuprates is a key question toward a unified understanding of the cuprate physics from long-range antiferromagnetism to superco…
Crossover of the high-energy spin fluctuations from collective triplons to localized magnetic excitations in doped Sr14-xCaxCu24O41 cuprate ladders
Y. Tseng, J. Thomas, W. Zhang +13
We studied the magnetic excitations in the quasi-one-dimensional (q-1D) ladder subsystem of Sr_(14-x) Ca_x Cu_24 O_41(SCCO) using Cu L_3-edge resonant inelastic X-ray scattering (R…
Dispersionless orbital excitations in (Li,Fe)OHFeSe superconductors
Qian Xiao, Wenliang Zhang, Teguh Citra Asmara +9
The superconducting critical temperature of intercalated iron-selenide superconductor (Li,Fe)OHFeSe (FeSe11111) can be increased to 42 K from 8 K of bulk FeSe. It…
Novel Cu-based dz2 order at a YBa2Cu3O7/ manganite interface
Roxana Gaina, Christopher W. Nicholson, Maxime Rumo +12
The interplay of nearly degenerate orders in quantum materials can lead to a myriad of emergent phases. A prominent case is that of the high-Tc cuprates for which the relationship…
