Trion gas on the surface of a failed excitonic insulator
Yuval Nitzav, Abigail Dishi, Himanshu Lohani +15
Trions, three-body bound states composed of an exciton and an additional charge, are typically fragile and require external excitation to form. Here, we report the spontaneous emer…
Magnetic Excitations of a Half-Filled Tl-based Cuprate
I. BiaÅo, Q. Wang, J. Küspert +21
Strong electron correlations drive Mott insulator transitions. Yet, there exists no framework to classify Mott insulators by their degree of correlation. Cuprate superconductors, w…
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…
Fermi surface and pseudogap in highly doped SrIrO
Y. Alexanian, A. de la Torre, S. McKweon Walker +18
The fate of the Fermi surface in bulk electron-doped SrIrO remains elusive, as does the origin and extension of its pseudogap phase. Here, we use high-resolution angle-…
Insulator-to-Metal Transition via Magnetic Reconstruction at Oxide Interfaces
Zengxing Lu, Jiatai Feng, Xuan Zheng +6
Ultrathin two-dimensional (2D) electronic systems at the interfaces of layered materials are highly desirable platforms for exploring of novel quantum phenomena and developing adva…
