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…
Flat Band Generation through Interlayer Geometric Frustration in Intercalated Transition Metal Dichalcogenides
Yawen Peng, Ren He, Peng Li +6
Electronic flat bands can lead to rich many-body quantum phases by quenching the electron's kinetic energy and enhancing many-body correlation. The reduced bandwidth can be realize…
Atomically-sharp magnetic soliton in the square-net lattice EuRhAlSi
Kevin Allen, Juba Bouaziz, Yichen Zhang +17
Topological spin textures are hallmark manifestations of competing interactions in magnetic matter. Their effective description by nonlinear field theories reflects an energetic fr…
Selective electron-phonon coupling strength from nonequilibrium optical spectroscopy: The case of MgB
S. Mor, F. Boschini, E. Razzoli +9
The coupling between quasiparticles and bosonic excitations rules the energy transfer pathways in condensed matter systems. The possibility of inferring the strength of specific co…
Robust spin splitting and fermiology in a layered altermagnet
Alessandro De Vita, Chiara Bigi, Davide Romanin +42
Altermagnetism defies conventional classifications of collinear magnetic phases, standing apart from ferromagnetism and antiferromagnetism with its unique combination of spin-depen…
Quantum oscillations and anisotropic magnetoresistance in the quasi-two-dimensional Dirac nodal line superconductor
Yuxiang Gao, Kevin Allen, Rose Albu Mustaf +8
Recent interest in quantum materials has focused on systems exhibiting both superconductivity and non-trivial band topology as material candidates to realize topological or unconve…
