SR study of time-reversal symmetry constraints and bulk superfluid response in LiFeAs
Rustem Khasanov, Hubertus Luetkens, Nikolai D. Zhigadlo
We report zero-field (ZF) and transverse-field (TF) muon-spin rotation/relaxation (SR) measurements on superconducting LiFeAs ( K) grown by a high…
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…
Thermodynamic evidence for a pressure-driven crossover from strong- to weak-coupling superconductivity in Pb
Rustem Khasanov
The thermodynamic critical field provides direct access to the superconducting condensation energy, yet its pressure dependence has been studied much less extensively t…
Pressure-Invariant Isotope Effect as Evidence for Electronically Driven Intertwined Order in PrNiO
Rustem Khasanov, Thomas J. Hicken, Igor Plokhikh +5
We report muon-spin rotation measurements of the pressure dependence of the oxygen-isotope (O/O) effect on the spin-density wave (SDW) transition in the trilayer Rudd…
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…
