Fermi surface and topology of multiband superconductor BeAu
Riccardo Vocaturo, Klaus Koepernik, Dániel Varjas +3
The chiral material BeAu was recently identified as a multiband type-I superconductor with a critical temperature of 3.2 K. As a member of the B20 crystal family (space group $P2_1…
Charge order in the Pr substituted YBaCuO from high-field Hall effect measurements
C. M. Duffy, M. Altangerel, S. Badoux +8
The mechanism of doping in the composite PrYBaCuO (Pr-YBCO) system is distinct from that of pure YBCO, offering a means to explore the requirements for…
Quantifying Twist Angles in Cuprate Heterostructures with Anisotropic Raman Signatures
Flavia Lo Sardo, Marina Esposito, Tommaso Confalone +9
Artificially engineered twisted van der Waals (vdW) heterostructures have unlocked new pathways for exploring emergent quantum phenomena and strongly correlated electronic states.…
Soft Mode Origin of Charge Ordering in Superconducting Kagome CsVSb
Philippa Helen McGuinness, Fabian Henssler, Manex Alkorta +12
Charge-density-wave (CDW) order and superconductivity coexist in the kagome metals AVSb (A=K, Cs, Rb), raising fundamental questions about the mechanisms driving their inte…
Orbital-Selective Band Structure Evolution in BaFeMAs (M = Cr, Co, Cu, Ru and Mn) Probed by Polarization-Dependent ARPES
K. R. Pakuszewski, M. R. Cantarino, I. Romanenko +7
We present a systematic study of the evolution of the band structure in the Fe-based superconductor family BaFeMAs (M = Cr, Co, Cu, Ru and Mn) using polarization-de…
Disorder-induced damping of spin excitations in Cr-doped BaFeAs
Marli R. Cantarino, Rafael M. P. Teixeira, R. Pakuszewski +9
In doped Hund's metals, such as the iron-based superconductors, effects like charge doping and chemical pressure are often considered the dominant factors. Partial chemical substit…
