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…
Emergent Surface Kondo Flat Band Driven by Competing Interactions in a Topological Ferromagnet
Nazar Zaremba, Susmita Changdar, Haojie Guo +28
A central goal of modern condensed matter physics is to uncover new quantum states of matter arising from the intertwined effects of strong electron correlations, magnetism, and ba…
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…
One-dimensional conduction channels in the correlated Mott NiS2 arising from obstructed Wannier charges
Mikel Iraola, Haojie Guo, Fabio Orlandi +9
NiS2, a compound characterized by its pyrite structure, uniquely bridges the realms of strong correlation physics and topology. While bulk NiS2 is known to be a Mott or charge-tran…
Ising domain wall networks from intertwined charge density waves in single-layer TiSe2
Wen Wan, Maria N. Gastiasoro, Daniel Muñoz-Segovia +3
When the period of an incommensurate charge density wave (ICDW) approaches an integer multiple of a lattice vector, the energy gain obtained from locking the period to the lattice…
Evidence for ground state coherence in a two-dimensional Kondo lattice
Wen Wan, Rishav Harsh, Antonella Meninno +6
Kondo lattices are ideal testbeds for the exploration of heavy-fermion quantum phases of matter. While our understanding of Kondo lattices has traditionally relied on complex bulk…
