Giant Kohn anomaly and chiral phonons in the charge density wave phase of 1H-NbSe
Susy Exists, Sougata Mardanya, Robert Markiewicz +6
Despite extensive investigations, many aspects of charge density waves (CDWs) remain elusive, especially the relative roles of electron-phonon coupling and Fermi surface nesting as…
A model for intertwined orders in cuprates
R. S. Markiewicz, M. Matzelle, A. Bansil
We model the intertwined orders in the cuprate pseudogap as a textured antiferromagnet (AFM), where the texture arises from confining competing phases on topological defects, i.e.,…
Strain-Induced Charge Density Waves with Emergent Topological States in Monolayer NbSe2
Wei-Chi Chiu, Sougata Mardanya, Robert Markiewicz +7
Emergence of topological states in strongly correlated systems, particularly two-dimensional (2D) transition-metal dichalcogenides, offers a platform for manipulating electronic pr…
Magnetism-Enhanced Strong Electron-Phonon Coupling in Infinite-Layer Nickelate
Ruiqi Zhang, Yanyong Wang, Manuel Engel +12
Intriguing analogies between the nickelates and the cuprates provide a promising avenue for unraveling the microscopic mechanisms underlying high- superconductivity. While ele…
