Direct Observation of Channelised Supercurrents in a Kagome Superconductor
Matthijs Rog, Tycho J. Blom, Reinier Q. Regter +9
Superconductors are many-body quantum states in which current flows without dissipation. Theory predicts that supercurrents follow a relatively simple spatial pattern in both conve…
Three-dimensional Foliated Fractional Quantum Hall Phases
Sahana Das, Navketan Batra, Andrea Kouta Dagnino +4
Foliated topological orders in three dimensions are layered systems in which anyons are free to move within a layer but cannot hop between them. A simple model with such a phase is…
Charge density wave in a band insulator
Md Shafayat Hossain, Wenhao Liu, Yuqi Zhang +20
Charge density wave (CDW) implies a periodic modulation of the charge density. Typically observed in metallic systems, CDWs arise from Fermi surface instabilities, resulting in the…
Many-body Euler topology
Axel Fünfhaus, Titus Neupert, Thilo Kopp +1
Integer and fractional Chern insulators exhibit a nonzero quantized anomalous Hall conductivity due to a spontaneous breaking of time reversal symmetry. To identify nontrivial topo…
