The Thermoelectric Effect and Its Natural Heavy Fermion Explanation in Twisted Bilayer and Trilayer Graphene
Dumitru Călugăru, Haoyu Hu, Rafael Luque Merino +3
We study the interacting transport properties of twisted bilayer graphene (TBG) using the topological heavy-fermion (THF) model. In the THF model, TBG comprises localized, correlat…
Cryo-Near-Field Photovoltage Microscopy of Heavy-Fermion Twisted Symmetric Trilayer Graphene
Sergi Batlle-Porro, Dumitru Calugaru, Haoyu Hu +7
Ever since the initial experimental observation of correlated insulators and superconductivity in the flat Dirac bands of magic angle twisted bilayer graphene, a search for the mic…
Evidence of heavy fermion physics in the thermoelectric transport of magic angle twisted bilayer graphene
Rafael Luque Merino, Dumitru Calugaru, Haoyu Hu +7
It has been recently postulated, that the strongly correlated flat bands of magicangle twisted bilayer graphene (MATBG) can host coexisting heavy and light carriers. While transpor…
PbCu(PO4)(OH): Phonon bands, Localized Flat Band Magnetism, Models, and Chemical Analysis
Yi Jiang, Scott B. Lee, Jonah Herzog-Arbeitman +12
In a series of recent reports, doped lead apatite (LK-99) has been proposed as a candidate ambient temperature and pressure superconductor. However, from both an experimental and t…
Thermal spin dynamics of Kitaev magnets scattering continua and magnetic field induced phases within a stochastic semiclassical approach
Oliver Franke, Dumitru Călugăru, Andreas Nunnenkamp +1
The honeycomb magnet RuCl is a prime candidate material for realizing the Kitaev quantum spin liquid (QSL), but it shows long-range magnetic order at low temperature. Never…
