Emergence of a Fluctuating Ground State in Y-kapellasite under Pressure

Dipranjan Chatterjee, Petr DoleÅ¾al, Federico Abbruciati +17

Y-kapellasite (Y $_{3}$ Cu $_{9}$ (OH) $_{19}$ Cl $_{8}$ ), which hosts an original anisotropic kagome sublattice, is a promising candidate for studying elusive and complex correlated physics. I…

Anatomy of anomalous Hall effect due to magnetic fluctuations

Ola Kenji Forslund, Xiaoxiong Liu, Soohyeon Shin +16

The anomalous Hall {\color{black} e}ffect (AHE) has emerged as a key indicator of time-reversal symmetry breaking (TRSB) and topological features in electronic band structures. Abs…
