Differentiated roles of Lifshitz transition on thermodynamics and superconductivity in La2-xSrxCuO4
Yong Zhong, Zhuoyu Chen, Su-Di Chen +7
The effect of Lifshitz transition on thermodynamics and superconductivity in hole-doped cuprates has been heavily debated but remains an open question. In particular, an observed p…
Traces of Electron-Phonon Coupling in One-Dimensional Cuprates
Ta Tang, Brian Moritz, Cheng Peng +2
The appearance of certain spectral features in one-dimensional (1D) cuprate materials has been attributed to a strong, extended attractive coupling between electrons. Here, using t…
A novel superstructure in epitaxially grown 1T-TaTe
Jinwoong Hwang, Yeongrok Jin, Canxun Zhang +13
The spontaneous formation of electronic orders is a crucial element for understanding complex quantum states and engineering heterostructures in two-dimensional materials. We repor…
Evidence for a spinon Kondo effect in cobalt atoms on single-layer 1T-TaSe
Yi Chen, Wen-Yu He, Wei Ruan +13
Quantum spin liquids (QSLs) are highly entangled, disordered magnetic states that arise in frustrated Mott insulators and host exotic fractional excitations such as spinons and cha…
A Broken Translational Symmetry State in an Infinite-Layer Nickelate
Matteo Rossi, Motoki Osada, Jaewon Choi +17
A defining signature of strongly correlated electronic systems is the existence of competing phases with similar ground state energies, resulting in a rich phase diagram. While in…
Expanding the momentum field of view in angle-resolved photoemission systems with hemispherical analyzers
Nicolas Gauthier, Jonathan A. Sobota, Heike Pfau +6
In photoelectron spectroscopy, the measured electron momentum range is intrinsically related to the excitation photon energy. Low photon energies eV are commonly encountered…
