Lifting the degeneracy of quantum spin liquid phase by uniaxial pressure
Shams Sohel Islam, Zurab Guguchia, Orion Gerguri +13
We report muon spin relaxation/rotation (SR) measurements of the candidate three-dimensional (3D) quantum spin liquid (QSL) PbCuTeO, hosting moments, under contr…
Direct High-Magnetic-Field Coupling to Stripe Order in a Cuprate Superconductor
Leonardo Martinelli, Izabela BiaÅo, 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…
Unified pressure and field response across distinct charge-order regimes in Ti-doped CsVSb
P. Krà l, S. S. Islam, Andrea N. Capa Salinas +10
Understanding the phase diagram of kagome superconductors from a microscopic perspective is crucial for clarifying the interplay between charge order and superconductivity. Ti-dope…
Correlated charge order intertwined with time-reversal symmetry-breaking nodal superconductivity in the dual flat band kagome superconductor CeRuSi
O. Gerguri, P. Krà l, M. Spitaler +19
Kagome materials provide a powerful platform for exploring how flat electronic bands promote symmetry-breaking quantum states, yet studies have so far focused mainly on kagome-deri…
The stripe state at 1/8 Ba doping hosts optimal superconductivity in La-214 cuprates under low in-plane stress
V. Sazgari, S. S. Islam, M. Lamotte +20
The cuprate system LaBaCuO (LBCO) exhibits a pronounced sensitivity to in-plane uniaxial stress, particularly near the 1/8 doping anomaly, where stripe order st…
Uniaxial stress enhanced anisotropic magnetoresistance and superconductivity in the kagome superconductor LaRuSi
P. Král, V. Sazgari, Yongheng Ge +10
Elucidating the role of the kagome electronic structure in determining the various quantum ground states is of fundamental importance. In this work, we employ in-plane uniaxial str…
