Mapping Strain and Spatial-Modulation Phase from Local Wave Vectors in Scanning Tunneling Microscopy
Xinze Yang, Sandra Sajan, Maria N. Gastiasoro +2
Spatially varying lattice distortions can produce local changes in electronic properties that are obscured by measurements averaging over extended regions. With its atomic-scale sp…
Two-phonon pairing and superconductivity in
Antonio Santacesaria, Cristiano Muzzi, Maria Eleonora Temperini +3
We explore the possibility that the two-phonon pairing mechanism proposed by Ngai can explain superconductivity in doped strontium titanate (STO). The two-phonon deformation potent…
Stacking-tuned superconductivity and competing charge-density-wave states in NbSe
Sandra Sajan, Xinze Yang, Haojie Guo +9
Layer stacking provides a powerful yet underexplored route for reshaping collective quantum order in van der Waals materials. Here we use high-resolution scanning tunneling microsc…
Spin-chiral electron-phonon coupling in metallic strontium titanate
N. Somun, L. Rogić, I. Khayr +12
Electron-phonon coupling (EPC) - the interaction between conduction electrons and quantized atomic vibrations - plays a central role in condensed matter physics and determines some…
Ferroaxial and nematic transitions in the charge density wave phase of 1T-TiSe
Sarah Edwards, Elliott Rosenberg, Ilaria Maccari +9
Charge density waves (CDWs) with multi-component order parameters can break unexpected symmetries through the interplay of nearly degenerate instabilities. In the widely investigat…
Moiré-induced symmetry breaking of charge order in van der Waals heterostructures
Sandra Sajan, Laura Pätzold, Tarushi Agarwal +10
Layered materials that stack different lattice symmetries are rare in nature. Misfit layered chalcogenides, which combine square and hexagonal lattices of rocksalt monochalcogenide…
