Distinct lattice and charge excitations in AV3Sb5 kagome superconductors
Dongjin Oh, Stefan Enzner, Lennart Klebl +12
The kagome superconductor family AV3Sb5 (A=Cs, Rb, K) provides a rich platform for exploring diverse electronic symmetry breaking phenomena, including superconductivity and various…
Correlations between superconducting and resistive anisotropies
Sayan Banerjee, Harley D. Scammell, Mathias S. Scheurer
There are multiple possible origins of transport anisotropies in metals and superconductors. For instance, rotational symmetry can be spontaneously broken in the normal state as a…
Theory of unconventional magnetism in a Cu-based kagome metal
Anja Wenger, Armando Consiglio, Hendrik Hohmann +6
Kagome metals have established a new arena for correlated electron physics. To date, the predominant experimental evidence centers around unconventional charge order, nematicity, a…
Group theory method for extracting order parameters from scanning tunneling microscopy data
Julian Ingham, Yu-Xiao Jiang, M. Zahid Hasan +1
Scanning tunneling microscopy (STM) is a powerful local probe of correlated electronic states. Here we present a group theoretical framework for the analysis of STM data, filtering…
Spin-orbit crossover and the origin of magnetic torque in kagome metals
Mathias S. Scheurer, Harley D. Scammell
Recent experiments on the kagome metal CsVSb reveal a curious phase transition-like feature: a nematic magnetic torque response that abruptly sets in at K,…
Exciton condensation from level repulsion: application to bilayer graphene
Harley D. Scammell, Oleg P. Sushkov
Exciton condensation in semiconductors and semimetals has long been predicted but remains elusive. In a semiconductor, condensation occurs when the exciton binding energy matches t…
