Enhancement of superconductivity by disorder in Remeika-type quasiskutterudites
Andrzej Ålebarski, Maciej M. MaÅka
Atomic-scale disorder is conventionally regarded as detrimental to superconductivity; however, under specific conditions, it can enhance superconducting properties. Here, we invest…
Probing frustrated spin systems with impurities
Maksymilian Kliczkowski, Jakub Grabowski, Maciej M. MaÅka
We investigate the effective interaction between two localized spin impurities embedded in a frustrated spin-1/2 Heisenberg chain. Treating the impurity spins as clas…
Griffiths phases in structurally disordered CeRhSn: Experimental evidence and theoretical modeling
Andrzej Ålebarski, Maciej M. MaÅka
Our report paves the way for insight into a structural disorder and its impact on the physical properties of strongly correlated electron systems (SCESs). In a critical regime, eac…
High Harmonic Tracking of Ultrafast Electron Dynamics across the Mott to Charge Density Wave Phase Transition
Marlena Dziurawiec, Jessica O. de Almeida, Mohit Lal Bera +6
Different insulator phases compete with each other in strongly correlated materials with simultaneous local and non-local interactions. It is known that the homogeneous Mott insula…
