Direct High-Magnetic-Field Coupling to Stripe Order in a Cuprate Superconductor
Leonardo Martinelli, Izabela Biało, Jens Oppliger +47
Superconductivity in cuprates emerges out of a complex normal state that hosts density waves, pseudogap physics, and strange metal properties. Here, we access this normal state by…
Four-layer charge density waves and chirality in CsVSb
Fernando de Juan, Mark H. Fischer
The kagome superconductor CsVSb is the only one in the AVSb family (A=K,Rb,Cs) that shows a charge-density-wave (CDW) ground state competing with…
Reduced pair breaking from extended disorder in unconventional superconductors: implications to 4Hb-TaS
Yuval Tsur, Mark H. Fischer, Jonathan Ruhman
Unconventional superconductivity is generally expected to be strongly suppressed by nonmagnetic disorder, as captured by Abrikosov--Gor'kov (AG) theory. However, several materials,…
Switchable half-quantum flux states in a ring of the kagome superconductor CsVSb
Shuo Wang, Ilaria Maccari, Xilin Feng +14
Magnetic flux quantization in units of is a defining feature of superconductivity, rooted in the charge-2e nature of Cooper pairs. In a ring geometry, the flux quantiz…
Spin currents in crystals with spin-orbit coupling: multi-band effects in an effective Hamiltonian formalism
K. V. Samokhin, M. Sigrist, M. H. Fischer
When focusing on a few essential bands in an effective description of a material to calculate observable quantities, the respective operators have to be adjusted accordingly. Ignor…
