Disentangling electron-boson interactions on the surface of a familiar ferromagnet
Røst, Håkon; Mazzola, Federico; Bakkelund, Johannes; Åsland, Anna Cecilie; Hu, Jinbang; Cooil, Simon Phillip; Polley, Craig; Wells, Justin William (Journal article; Peer reviewed, 2024)We report energy renormalizations from electron-phonon and electron-magnon interactions in spin minority surface resonances on Ni(111). The different interactions are identified, disentangled, and quantified from the ... -
One-dimensional spin-polarized surface states: A comparison of Bi(112) with other vicinal bismuth surfaces
Åsland, Anna Cecilie; Bakkelund, Johannes; Thingstad, Even; Røst, Håkon; Cooil, Simon Phillip; Hu, Jinbang; Vobornik, Ivana; Fujii, Jun; Sudbø, Asle; Wells, Justin William; Mazzola, Federico (Journal article; Peer reviewed, 2023)Vicinal surfaces of bismuth are unique test beds for investigating one-dimensional (1D) spin-polarized surface states that may one day be used in spintronic devices. In this paper, such states have been observed for the ... -
Phonon-Mediated Quasiparticle Lifetime Renormalizations in Few-Layer Hexagonal Boron Nitride
Røst, Håkon; Cooil, Simon Phillip; Åsland, Anna Cecilie; Hu, Jinbang; Ali, Ayaz; Taniguchi, Takashi; Watanabe, Kenji; Belle, Branson Delano; Holst, Bodil; Sadowski, Jerzy; Mazzola, Federico; Wells, Justin William (Journal article; Peer reviewed, 2023)Understanding the collective behavior of the quasiparticles in solid-state systems underpins the field of non-volatile electronics, including the opportunity to control many-body effects for well-desired physical phenomena ...
