Hallmark Signatures of Electronic Pairing in Two-Photon Two-Electron Coincidence Angle-Resolved Photoemission Spectroscopy
Janez Bonca, Alberto Nocera, Andrea Damascelli +1
Understanding strongly correlated quantum materials remains a central challenge in condensed matter physics and materials science. While angle-resolved photoemission spectroscopy (…
Fingerprints of preformed pairs in two-electron angle-resolved photoemission spectroscopy
Janez BonÄa, Andrea Damascelli, Mona Berciu
We use variational exact diagonalization (VED) to calculate the two-electron removal spectral weight for the Hubbard-Holstein model, starting from the ground-state with two electro…
Direct Fabrication of a Superconducting Two-Dimensional Electron Gas on KTaO3(111) via Mg-Induced Surface Reduction
Chun Sum Brian Pang, Bruce A. Davidson, Fengmiao Li +16
Two-dimensional electron gases (2DEGs) at the surfaces of KTaO3 have become an exciting platform for exploring strong spin-orbit coupling, Rashba physics, and low-carrier-density s…
Percolative Pathway to Stripe Order in KTaO3-Based Superconductivity
Zhihao Chen, Chun Sum Brian Pang, Meng Yang +8
The sensitivity of low dimensional superconductors to fluctuations gives rise to emergent behaviors beyond the conventional Bardeen Cooper Schrieffer framework. Anisotropy is one s…
Critical Role of Disorder for Superconductivity in the Series of Epitaxial Ti(O,N) Films
Fengmiao Li, Oliver Dicks, Myung-Geun Han +14
Realizing experimental control of superconductivity is of paramount importance to advancing both basic research and technological applications. Disorder, generally existing in most…
