Quasiparticle interference as a tool to study quantum materials
Luke C. Rhodes, Yuhki Kohsaka, Tetsuo Hanaguri +2
To understand the properties of quantum materials a detailed knowledge of the material's low energy electronic structure is key. Details of the electronic structure drive the groun…
Interlayer interactions reshape charge-density wave through electronic elasticity in 4H-TaS
Carolina A. Marques, Martha Rösler, Berk Zengin +7
Incommensurate charge-density waves (CDWs) in layered quantum materials frequently exhibit widely varying ordering wave vectors, even among nominally identical samples, obscuring t…
How to measure loop currents in scanning tunneling microscopy
Victoire Morisseau, Luke C. Rhodes, Peter Wahl +1
The emergence of loop current phases, where spontaneous loops of orbital currents give rise to a weak local magnetic moments, has been proposed to exist in a number of quantum mate…
Imaging stripe dynamics in trilayer nickelate LaNiO
Uladzislau Mikhailau, Luke Rhodes, Siri A. Berge +5
Since the discovery of high-temperature superconductivity in nickelate superconductors, it is an open question how closely the superconducting state resembles that of cuprate super…
Revealing Hund superdispersion with tunneling spectroscopy
Luke C. Rhodes, Fabian B. Kugler, Olivier Gingras +5
In cuprate superconductors, electron-electron repulsion results in characteristic spectroscopic features known as `waterfalls', where the sharp quasiparticle dispersion transitions…
calcQPI: A versatile tool to simulate quasiparticle interference
Peter Wahl, Luke C. Rhodes, Carolina A. Marques
Quasiparticle interference imaging (QPI) provides a route to characterize electronic structure from real space images acquired using scanning tunneling microscopy. It emerges due t…
